今天就跟大家聊聊有关ASP.NET MVC5网站开发中如何实现用户添加和浏览，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。
一、数据存储层
1、查找分页列表
在写用户列表时遇到了问题，考虑到用户可能会较多的情况需要分页，在数据存储层写的方法是public IQueryable<T> FindPageList<TKey>(int pageSize, int pageIndex, out int totalNumber, Expression<Func<T, bool>> where, Expression<Func<T, TKey>> order, bool asc)。
主要问题就在红色的order这儿，这个参数不好传递，比如：如果是已ID来排序哪TKey类型是int，如果以注册时间来排序哪TKey类型就是datetime。如果我在业务逻辑层写一个函数可以支持选择排序类型，那么我没有办法声明一个变量既可以存储TKey为int的值，又可以存储datetime的值,那么排序就要写成下面这个样子，感觉不舒服。
//排序
switch(order)
{
case 0://ID升序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.UserID, true).ToList();
break;
case 1://ID降序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.UserID, false).ToList();
break;
case 2://注册时间降序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.RegTime, true).ToList();
break;
case 3://注册时间升序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.RegTime, false).ToList();
break;
case 4://最后登录时间升序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.LastLoginTime, true).ToList();
break;
case 5://最后登录时间降序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.LastLoginTime, false).ToList();
break;
default://ID降序
_users.Items = Repository.FindPageList((int)pageSize, (int)pageIndex, out _users.TotalNumber, _where, u => u.UserID, false).ToList();
break;
}后来将TKey设为dynamic类型，不论Expression<Func<T, dynamic>> order = u => u.UserID 或者u => u.RegTime都可以编译通过，但是一运行就会出错。
前几天没写博客一直在考虑这个问题，后来还是换成用字符串的方式来动态排序。 步骤如下：
Ninesky.DataLibrary[右键]->添加->类，输入类名OrderParam
namespace Ninesky.DataLibrary
{
/// <summary>
/// 排序参数
/// </summary>
public class OrderParam
{
/// <summary>
/// 属性名
/// </summary>
public string PropertyName { get; set; }
/// <summary>
/// 排序方式
/// </summary>
public OrderMethod Method { get; set; }
}
/// <summary>
/// 排序方式
/// </summary>
public enum OrderMethod
{
/// <summary>
/// 正序
/// </summary>
ASC,
/// <summary>
/// 倒序
/// </summary>
DESC
}
}打开Ninesky.DataLibrary/Repository.cs,将方法public IQueryable<T> FindPageList<TKey>(int pageSize, int pageIndex, out int totalNumber, Expression<Func<T, bool>> where, Expression<Func<T, TKey>> order, bool asc)的代码修改为
/// <summary>
/// 查找分页列表
/// </summary>
/// <param name="pageSize">每页记录数。必须大于1</param>
/// <param name="pageIndex">页码。首页从1开始，页码必须大于1</param>
/// <param name="totalNumber">总记录数</param>
/// <param name="where">查询表达式</param>
/// <param name="orderParams">排序【null-不设置】</param>
public IQueryable<T> FindPageList(int pageSize, int pageIndex, out int totalNumber, Expression<Func<T, bool>> where, OrderParam[] orderParams)
{
if (pageIndex < 1) pageIndex = 1;
if (pageSize < 1) pageSize = 10;
IQueryable<T> _list = DbContext.Set<T>().Where(where);
var _orderParames = Expression.Parameter(typeof(T), "o");
if (orderParams != null && orderParams.Length > 0)
{
for (int i = 0; i < orderParams.Length; i++)
{
//根据属性名获取属性
var _property = typeof(T).GetProperty(orderParams[i].PropertyName);
//创建一个访问属性的表达式
var _propertyAccess = Expression.MakeMemberAccess(_orderParames, _property);
var _orderByExp = Expression.Lambda(_propertyAccess, _orderParames);
string _orderName = orderParams[i].Method == OrderMethod.ASC ? "OrderBy" : "OrderByDescending";
MethodCallExpression resultExp = Expression.Call(typeof(Queryable), _orderName, new Type[] { typeof(T), _property.PropertyType }, _list.Expression, Expression.Quote(_orderByExp));
_list = _list.Provider.CreateQuery<T>(resultExp);
}
}
totalNumber = _list.Count();
return _list.Skip((pageIndex - 1) * pageIndex).Take(pageSize);
}方法中排序参数（OrderParam[]） 使用数组，是考虑到多级排序的情况。对FindPageList重载代码进行修改，修改完的代码如下：
//查找实体分页列表
#region FindPageList
/// <summary>
/// 查找分页列表
/// </summary>
/// <param name="pageSize">每页记录数。必须大于1</param>
/// <param name="pageIndex">页码。首页从1开始，页码必须大于1</param>

public IQueryable<T> FindPageList(int pageSize, int pageIndex, out int totalNumber)
{
OrderParam _orderParam = null;
return FindPageList(pageSize, pageIndex, out totalNumber, _orderParam);
}
/// <summary>

/// <returns></returns>
public IQueryable<T> FindPageList(int pageSize, int pageIndex, out int totalNumber, OrderParam orderParam)
{
return FindPageList(pageSize, pageIndex, out totalNumber, (T)=> true, orderParam);
}
/// <summary>

{

if (orderParam != null) _orderParams = new OrderParam[] { orderParam };
return FindPageList(pageSize, pageIndex, out totalNumber, where, _orderParams);
}

{
if (pageIndex < 1) pageIndex = 1;
if (pageSize < 1) pageSize = 10;
IQueryable<T> _list = DbContext.Set<T>().Where(where);
var _orderParames = Expression.Parameter(typeof(T), "o");
if (orderParams != null && orderParams.Length > 0)
{
for (int i = 0; i < orderParams.Length; i++)
{

var _property = typeof(T).GetProperty(orderParams[i].PropertyName);
//创建一个访问属性的表达式
var _propertyAccess = Expression.MakeMemberAccess(_orderParames, _property);
var _orderByExp = Expression.Lambda(_propertyAccess, _orderParames);
string _orderName = orderParams[i].Method == OrderMethod.ASC ? "OrderBy" : "OrderByDescending";
MethodCallExpression resultExp = Expression.Call(typeof(Queryable), _orderName, new Type[] { typeof(T), _property.PropertyType }, _list.Expression, Expression.Quote(_orderByExp));
_list = _list.Provider.CreateQuery<T>(resultExp);
}
}
totalNumber = _list.Count();
return _list.Skip((pageIndex - 1) * pageIndex).Take(pageSize);
}
#endregion2、查找列表
基于分页列表同样的原因，对FindList方法也进行修改。
//查找实体列表
#region FindList
/// <summary>
/// 查找实体列表
/// </summary>
/// <returns></returns>
public IQueryable<T> FindList()
{
return DbContext.Set<T>();
}

return DbContext.Set<T>().Where(where).Take(number);
}
/// <summary>

/// </summary>
/// <param name="where">查询Lambda表达式</param>
/// <param name="orderParam">排序参数</param>
/// <returns></returns>
public IQueryable<T> FindList(Expression<Func<T, bool>> where, OrderParam orderParam)

{
OrderParam[] _orderParams = null;
if (orderParam != null) _orderParams = new OrderParam[] { orderParam };
return FindList(where, _orderParams, number);
}
/// <summary>

public IQueryable<T> FindList(Expression<Func<T, bool>> where, OrderParam[] orderParams, int number)
{
var _list = DbContext.Set<T>().Where(where);
var _orderParames = Expression.Parameter(typeof(T), "o");
if (orderParams != null && orderParams.Length > 0)
{
for (int i = 0; i < orderParams.Length; i++)
{
//根据属性名获取属性
var _property = typeof(T).GetProperty(orderParams[i].PropertyName);
//创建一个访问属性的表达式
var _propertyAccess = Expression.MakeMemberAccess(_orderParames, _property);
var _orderByExp = Expression.Lambda(_propertyAccess, _orderParames);
string _orderName = orderParams[i].Method == OrderMethod.ASC ? "OrderBy" : "OrderByDescending";
MethodCallExpression resultExp = Expression.Call(typeof(Queryable), _orderName, new Type[] { typeof(T), _property.PropertyType }, _list.Expression, Expression.Quote(_orderByExp));
_list = _list.Provider.CreateQuery<T>(resultExp);
}
}
if (number > 0) _list = _list.Take(number);
return _list;
}
#endregion二、业务逻辑层
1、用户模型
Ninesky.Core【右键】->添加->类，输入类名User。
引用System.ComponentModel.DataAnnotations命名空间
using System;
using System.ComponentModel.DataAnnotations;
namespace Ninesky.Core
{
/// <summary>
/// 用户模型
/// </summary>
public class User
{
[Key]
public int UserID { get; set; }
/// <summary>
/// 角色ID
/// </summary>
[Required(ErrorMessage = "必须输入{0}")]
[Display(Name = "角色ID")]
public int RoleID { get; set; }
/// <summary>
/// 用户名
/// </summary>
[StringLength(50, MinimumLength = 4, ErrorMessage = "{0}长度为{2}-{1}个字符")]
[Display(Name = "用户名")]
public string Username { get; set; }
/// <summary>
/// 名称【可做昵称、真实姓名等】
/// </summary>
[StringLength(20, ErrorMessage = "{0}必须少于{1}个字符")]
[Display(Name = "名称")]
public string Name { get; set; }
/// <summary>
/// 性别【0-女，1-男，2-保密】
/// </summary>
[Required(ErrorMessage = "必须输入{0}")]
[Range(0,2,ErrorMessage ="{0}范围{1}-{2}")]
[Display(Name = "性别")]
public int Sex { get; set; }
/// <summary>
/// 密码
/// </summary>
[DataType(DataType.Password)]
[StringLength(256, ErrorMessage = "{0}长度少于{1}个字符")]
[Display(Name = "密码")]
public string Password { get; set; }
/// <summary>
/// Email
/// </summary>
[DataType(DataType.EmailAddress)]
[StringLength(50, MinimumLength = 4, ErrorMessage = "{0}长度为{2}-{1}个字符")]
[Display(Name = "Email")]
public string Email { get; set; }
/// <summary>
/// 最后登录时间
/// </summary>
[DataType(DataType.DateTime)]
[Display(Name = "最后登录时间")]
public Nullable<DateTime> LastLoginTime { get; set; }
/// <summary>
/// 最后登录IP
/// </summary>
[Display(Name = "最后登录IP")]
public string LastLoginIP { get; set; }
/// <summary>
/// 注册时间
/// </summary>
[Required(ErrorMessage = "必须输入{0}")]
[Display(Name = "注册时间")]
public DateTime RegTime { get; set; }
/// <summary>
/// 角色
/// </summary>
public virtual Role Role { get; set; }
}
}用户名、密码和Email未设置成必填是考虑到，以后可以扩展QQ账号、微博账号等Owin方式登录等功能，用Owin登录的账号不会有这几个参数。对于用户添加和注册，可以写一个视图模型进行验证。
2、添加表映射
打开Ninesky.Core/NineskyContext.cs，添加Users表映射（红框部分）
3、更新数据表
在【工具栏】->【工具】->NuGet包管理器->程序包管理器控制台，运行命令Update-Database。
4、用户管理类
Ninesky.Core【右键】->添加->类，输入类名UserManager，类继承自BaseManager<User>
引用命名空间：using Ninesky.Core.Types; using Ninesky.DataLibrary;
因一般网站用户的数量肯能要较多，在显示用户列表的时候要分页显示，在数据存储层（Ninesky.DataLibrary）的Repository类中 public IQueryable<T> FindPageList<TKey>(int pageSize, int pageIndex, out int totalNumber, Expression<Func<T, bool>> where, Expression<Func<T, TKey>> order, bool asc)等分页方法，方法参数where为Lambda表达式树，在UserManager类的方法中我希望动态构造表达式树，这里需要借助一个小工具LINQKit。
Ninesky.Core->引用【右键】->管理NuGet程序包。
在NuGet包管理器中搜索linqkit，安装LinqKit最新版本。
在UserController中引用命名空间using LinqKit;
4.1 分页列表
添加FindPageList方法，代码如下：
/// <summary>
/// 分页列表
/// </summary>
/// <param name="pagingUser">分页数据</param>
/// <param name="roleID">角色ID</param>
/// <param name="username">用户名</param>
/// <param name="name">名称</param>
/// <param name="sex">性别</param>
/// <param name="email">Email</param>
/// <param name="order">排序【null（默认）-ID降序，0-ID升序，1-ID降序，2-注册时间降序，3-注册时间升序，4-最后登录时间升序，5-最后登录时间降序】</param>
/// <returns></returns>
public Paging<User> FindPageList(Paging<User> pagingUser, int? roleID, string username, string name, int? sex, string email, int? order)
{
//查询表达式
var _where = PredicateBuilder.True<User>();
if (roleID != null && roleID > 0) _where = _where.And(u => u.RoleID == roleID);
if (!string.IsNullOrEmpty(username)) _where = _where.And(u => u.Username.Contains(username));
if (!string.IsNullOrEmpty(name)) _where = _where.And(u => u.Name.Contains(name));
if (sex != null && sex >= 0 && sex <= 2) _where = _where.And(u => u.Sex == sex);
if (!string.IsNullOrEmpty(email)) _where = _where.And(u => u.Email.Contains(email));
//排序
OrderParam _orderParam;
switch(order)
{
case 0://ID升序
_orderParam = new OrderParam() { PropertyName = "UserID", Method = OrderMethod.ASC };
break;
case 1://ID降序
_orderParam = new OrderParam() { PropertyName = "UserID", Method = OrderMethod.DESC };
break;
case 2://注册时间降序
_orderParam = new OrderParam() { PropertyName = "RegTime", Method = OrderMethod.ASC };
break;
case 3://注册时间升序
_orderParam = new OrderParam() { PropertyName = "RegTime", Method = OrderMethod.DESC };
break;
case 4://最后登录时间升序
_orderParam = new OrderParam() { PropertyName = "LastLoginTime", Method = OrderMethod.ASC };
break;
case 5://最后登录时间降序
_orderParam = new OrderParam() { PropertyName = "LastLoginTime", Method = OrderMethod.DESC };
break;
default://ID降序
_orderParam = new OrderParam() { PropertyName = "UserID", Method = OrderMethod.DESC };
break;
}
pagingUser.Items = Repository.FindPageList(pagingUser.PageSize,pagingUser.PageIndex, out pagingUser.TotalNumber, _where.Expand(),_orderParam).ToList();
return pagingUser;
}4.2 判断用户名是否存在
添加HasUsername方法，代码如下
/// <summary>
/// 用户名是否存在
/// </summary>
/// <param name="accounts">用户名[不区分大小写]</param>
/// <returns></returns>
public bool HasUsername(string username)
{
return base.Repository.IsContains(u => u.Username.ToUpper() == username.ToUpper());
}4.3判断Email是否存在
添加HasEmail方法，代码如下
/// <summary>
/// Email是否存在
/// </summary>
/// <param name="email">Email[不区分大小写]</param>
/// <returns></returns>
public bool HasEmail(string email)
{
return base.Repository.IsContains(u => u.Email.ToUpper() == email.ToUpper());
}4.4 添加用户
因添加用户时，账号和Email不能重复所以添加前先判断一下用户名和密码是否存在。这里用户名为空时不进行判断是因为考虑有可能以后使用可能用QQ等其他方式登录。
/// <summary>
/// 添加【返回值Response.Code:0-失败，1-成功，2-账号已存在，3-Email已存在】
/// </summary>
/// <param name="user">用户</param>
/// <returns></returns>
public override Response Add(User user)
{
Response _resp = new Response();
//账号是否存在
if (!string.IsNullOrEmpty(user.Username) && HasUsername(user.Username))
{
_resp.Code = 2;
_resp.Message = "用户名已存在";
}
//Email是否存在
if (!string.IsNullOrEmpty(user.Email) && HasUsername(user.Email))
{
_resp.Code = 3;
_resp.Message = "Email已存在";
}
if(_resp.Code == 0) _resp = base.Add(user);
return _resp;
}三、展示层
Ninesky.Web/Areas/Control/Controllers【右键】->添加->控制器。选择 MVC5 控制器 – 空, 输入控制器名称UserController。
在控制器中引入命名空间Ninesky.Core;（1）
为控制器添加身份验证[AdminAuthorize]（2）
添加变量private RoleManager roleManager = new RoleManager();（3）
1、用户浏览
1.1、分页列表方法
在UserController中添加方法PageListJson，返回Json格式的分页数据。
/// <summary>
/// 分页列表【json】
/// </summary>
/// <param name="roleID">角色ID</param>
/// <param name="username">用户名</param>
/// <param name="name">名称</param>
/// <param name="sex">性别</param>
/// <param name="email">Email</param>
/// <param name="pageIndex">页码</param>
/// <param name="pageSize">每页记录数</param>
/// <param name="order">排序</param>
/// <returns>Json</returns>
public ActionResult PageListJson(int? roleID, string username,string name,int? sex,string email,int? pageNumber, int? pageSize,int? order)
{
Paging<User> _pagingUser = new Paging<Core.User>();
if (pageNumber != null && pageNumber > 0) _pagingUser.PageIndex = (int)pageNumber;
if (pageSize != null && pageSize > 0) _pagingUser.PageSize = (int)pageSize;
var _paging = userManager.FindPageList(_pagingUser, roleID, username, name, sex, email, null);
return Json(new { total = _paging.TotalNumber, rows = _paging.Items });
}1.2、默认页视图
在UserController中添加Index方法
/// <summary>
/// 默认页
/// </summary>
/// <returns></returns>
public ActionResult Index()
{
return View();
}在Index 方法上点右键 –>添加->视图
@{
ViewBag.Title = "用户管理";
}
@section SideNav{@Html.Partial("SideNavPartialView")}
<ol class="breadcrumb">
<li><span class="glyphicon glyphicon-home"></span> @Html.ActionLink("首页", "Index", "Home")</li>
<li class="active">@Html.ActionLink("用户管理", "Index", "User")</li>
</ol>
<table id="usergrid"></table>
@section style{
@Styles.Render("~/Content/bootstrapplugincss")
}
@section scripts{
@Scripts.Render("~/bundles/jqueryval")
@Scripts.Render("~/bundles/bootstrapplugin")
<script type="text/javascript">
$(document).ready(function () {
//表格
var $table = $('#usergrid');
$table.bootstrapTable({
showRefresh: true,
showColumns: true,
pagination: true,
sidePagination: "server",
pageList:"[5, 10, 20, 50, 100]",
method: "post",
url: "@Url.Action("PageListJson")",
columns: [
{ title: "ID", field: "UserID" },
{ title: "角色", field: "RoleID" },
{ title: "用户名", field: "Username" },
{ title: "名称", field: "Name", formatter: function (value, row, index) { return "<a href='@Url.Action("Modify", "User")/" + row.UserID + "'>" + value + "</a>" } },
{ title: "性别", field: "Sex" },
{ title: "Email", field: "Email", visible:false },
{ title: "最后登录时间", field: "LastLoginTime" },
{ title: "最后登录IP", field: "LastLoginIP", visible:false },
{ title: "注册时间", field: "RegTime",visible:false },
{ title: "操作", field: "UserID", formatter: function (value) { return "<a class='btn btn-sm btn-danger' data-operation='deleteuser' data-value='" + value + "'>删除</a>" } }
],
onLoadSuccess: function () {
//删除按钮
//删除按钮结束
}
});
//表格结束
});
</script>
}1.3侧导航局部视图
Ninesky.Web/Areas/Control/Views/User【右键】->添加->视图，输入视图名称
<div class="panel panel-default">
<div class="panel-heading">
<div class="panel-title"><span class="glyphicon glyphicon-user"></span> 用户管理</div>
</div>
<div class="panel-body">
<div class="list-group">
<div class="list-group-item"><span class="glyphicon glyphicon-plus"></span> @Html.ActionLink("添加用户", "Add", "User")</div>
<div class="list-group-item"><span class="glyphicon glyphicon-list"></span> @Html.ActionLink("用户管理", "Index", "User")</div>
</div>
</div>
</div>2、添加用户
2.1 添加用户视图模型
Ninesky.Web/Areas/Control/Models【右键】->添加->“AddUserViewModel”
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;
namespace Ninesky.Web.Areas.Control.Models
{
/// <summary>
/// 添加用户视图模型类
/// </summary>
public class AddUserViewModel
{
/// <summary>
/// 角色ID
/// </summary>
[Required(ErrorMessage = "必须选择{0}")]
[Display(Name = "角色ID")]
public int RoleID { get; set; }
/// <summary>
/// 用户名
/// </summary>
[Remote("CanUsername","User",HttpMethod = "Post", ErrorMessage ="用户名已存在")]
[StringLength(50, MinimumLength = 4, ErrorMessage = "{0}长度为{2}-{1}个字符")]
[Required(ErrorMessage = "必须输入{0}")]
[Display(Name = "用户名")]
public string Username { get; set; }
/// <summary>
/// 姓名【可做昵称、真实姓名等】
/// </summary>
[StringLength(20, ErrorMessage = "{0}必须少于{1}个字符")]
[Display(Name = "姓名")]
public string Name { get; set; }
/// <summary>
/// 性别【0-女，1-男，2-保密】
/// </summary>
[Required(ErrorMessage = "必须选择{0}")]
[Range(0, 2, ErrorMessage = "{0}范围{1}-{2}")]
[Display(Name = "性别")]
public int Sex { get; set; }
/// <summary>
/// 密码
/// </summary>
[Required(ErrorMessage = "必须输入{0}")]
[DataType(DataType.Password)]
[StringLength(256, ErrorMessage = "{0}长度少于{1}个字符")]
[Display(Name = "密码")]
public string Password { get; set; }
/// <summary>
/// 确认密码
/// </summary>
[System.ComponentModel.DataAnnotations.Compare("Password",ErrorMessage ="两次输入的密码不一致")]
[DataType(DataType.Password)]
[Display(Name = "确认密码")]
public string ConfirmPassword { get; set; }
/// <summary>
/// Email
/// </summary>
[Required(ErrorMessage = "必须输入{0}")]
[DataType(DataType.EmailAddress)]
[Remote("CanEmail", "User",HttpMethod = "Post", ErrorMessage = "Email已存在")]
[StringLength(50, MinimumLength = 4, ErrorMessage = "{0}长度为{2}-{1}个字符")]
[Display(Name = "Email")]
public string Email { get; set; }
}
}模型中使用到了远程验证（Remote）、属性比较（Compare）等验证方式。
2.2用户名和Email远程验证方法
在UserController中添加CanUsername和CanEmail方法
/// <summary>
/// 用户名是否可用
/// </summary>
/// <param name="UserName">用户名</param>
/// <returns></returns>
[HttpPost]
public JsonResult CanUsername(string UserName)
{
return Json(!userManager.HasUsername(UserName));
}
/// <summary>
/// Email是否存可用
/// </summary>
/// <param name="Email">Email</param>
/// <returns></returns>
[HttpPost]
public JsonResult CanEmail(string Email)
{
return Json(!userManager.HasEmail(Email));
}2.3 添加用户页面
在UserController中添加Add方法
/// <summary>
/// 添加用户
/// </summary>
/// <returns></returns>
public ActionResult Add()
{
//角色列表
var _roles = new RoleManager().FindList();
List<SelectListItem> _listItems = new List<SelectListItem>(_roles.Count());
foreach(var _role in _roles)
{
_listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() });
}
ViewBag.Roles = _listItems;
//角色列表结束
return View();
}方法中向视图传递角色列表ViewBag.Roles
右键添加视图
代码如下：
@model Ninesky.Web.Areas.Control.Models.AddUserViewModel
@{

@Scripts.Render("~/bundles/jqueryval")2.4添加处理方法
UserController中添加Add(AddUserViewModel userViewModel)方法
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Add(AddUserViewModel userViewModel)
{
if (userManager.HasUsername(userViewModel.Username)) ModelState.AddModelError("Username","用户名已存在");
if (userManager.HasEmail(userViewModel.Email)) ModelState.AddModelError("Email", "Email已存在");
if (ModelState.IsValid)
{
Core.User _user = new Core.User();
_user.RoleID = userViewModel.RoleID;
_user.Username = userViewModel.Username;
_user.Name = userViewModel.Name;
_user.Sex = userViewModel.Sex;
_user.Password = Core.General.Security.SHA256(userViewModel.Password);
_user.Email = userViewModel.Email;
_user.RegTime = System.DateTime.Now;
var _response = userManager.Add(_user);
if (_response.Code == 1) return View("Prompt",new Prompt() { Title="添加用户成功",
Message="您已成功添加了用户【"+ _response.Data.Username+ "（"+ _response.Data.Name + "）】",
Buttons= new List<string> {"<a href=\"" + Url.Action("Index", "User") + "\" class=\"btn btn-default\">用户管理</a>",
"<a href=\"" + Url.Action("Details", "User",new { id= _response.Data.UserID }) + "\" class=\"btn btn-default\">查看用户</a>",
"<a href=\"" + Url.Action("Add", "User") + "\" class=\"btn btn-default\">继续添加</a>"} });
else ModelState.AddModelError("", _response.Message);
}
//角色列表
var _roles = new RoleManager().FindList();
List<SelectListItem> _listItems = new List<SelectListItem>(_roles.Count());
foreach (var _role in _roles)
{
_listItems.Add(new SelectListItem() { Text = _role.Name, Value = _role.RoleID.ToString() });
}
ViewBag.Roles = _listItems;
//角色列表结束
return View(userViewModel);
}2.5添加成功提示
UserController中[右键]添加视图－Prompt
@model Ninesky.Web.Models.Prompt
@{
ViewBag.Title = "提示";
}
@section SideNav{@Html.Partial("SideNavPartialView")}
<ol class="breadcrumb">
<li><span class="glyphicon glyphicon-home"></span> @Html.ActionLink("首页", "Index", "Home")</li>
<li class="active"> @Html.ActionLink("用户管理", "Index", "User")</li>
</ol>
@Html.Partial("PromptPartialView", Model)2.6 添加提示消息局部视图
Ninesky.Web/Areas/Control/Views/Shared【右键】->添加->视图。视图名为PromptPartialView。
代码如下：
@model Ninesky.Web.Models.Prompt
<div class="panel panel-default">
<div class="panel-heading"><div class="panel-title">@Model.Title</div></div>
<div class="panel-body">
<p>@Html.Raw(Model.Message)</p>
@if (Model.Buttons != null && Model.Buttons.Count > 0)
{
<p>
@foreach (var item in Model.Buttons)
{
@Html.Raw(item + " ")
}
</p>
}
</div>
</div>运行效果
