在C# MVC框架中,业务流程管理通常涉及到以下几个方面:
Order
的模型类,其中包含订单相关的属性和方法。public class Order
{
public int Id { get; set; }
public string CustomerName { get; set; }
public DateTime OrderDate { get; set; }
public decimal TotalAmount { get; set; }
public OrderStatus Status { get; set; }
public void PlaceOrder()
{
// 业务逻辑:验证库存、创建订单记录等
}
public void UpdateStatus(OrderStatus newStatus)
{
// 业务逻辑:更新订单状态
}
}
<!-- Views/Order/Index.cshtml -->
@model List<Order>
<h1>订单列表</h1>
@foreach (var order in Model)
{
<div>
<h2>@order.CustomerName</h2>
<p>订单日期:@order.OrderDate</p>
<p>总金额:@order.TotalAmount</p>
<p>状态:@order.Status</p>
<button asp-action="Edit" asp-route-id="@order.Id">编辑</button>
<button asp-action="Delete" asp-route-id="@order.Id">删除</button>
</div>
}
public class OrderController : Controller
{
private readonly IOrderService _orderService;
public OrderController(IOrderService orderService)
{
_orderService = orderService;
}
public IActionResult Index()
{
var orders = _orderService.GetOrders();
return View(orders);
}
public IActionResult Edit(int id)
{
var order = _orderService.GetOrderById(id);
return View(order);
}
[HttpPost]
public IActionResult Edit(Order order)
{
if (ModelState.IsValid)
{
_orderService.UpdateOrder(order);
return RedirectToAction("Index");
}
return View(order);
}
public IActionResult Delete(int id)
{
_orderService.DeleteOrder(id);
return RedirectToAction("Index");
}
}
public interface IOrderService
{
List<Order> GetOrders();
Order GetOrderById(int id);
void UpdateOrder(Order order);
void DeleteOrder(int id);
}
public class OrderService : IOrderService
{
private readonly IOrderRepository _orderRepository;
public OrderService(IOrderRepository orderRepository)
{
_orderRepository = orderRepository;
}
public List<Order> GetOrders()
{
return _orderRepository.GetOrders();
}
public Order GetOrderById(int id)
{
return _orderRepository.GetOrderById(id);
}
public void UpdateOrder(Order order)
{
_orderRepository.UpdateOrder(order);
}
public void DeleteOrder(int id)
{
_orderRepository.DeleteOrder(id);
}
}
public interface IOrderRepository
{
List<Order> GetOrders();
Order GetOrderById(int id);
void UpdateOrder(Order order);
void DeleteOrder(int id);
}
public class OrderRepository : IOrderRepository
{
private readonly ApplicationDbContext _context;
public OrderRepository(ApplicationDbContext context)
{
_context = context;
}
public List<Order> GetOrders()
{
return _context.Orders.ToList();
}
public Order GetOrderById(int id)
{
return _context.Orders.Find(id);
}
public void UpdateOrder(Order order)
{
_context.Orders.Update(order);
_context.SaveChanges();
}
public void DeleteOrder(int id)
{
var order = _context.Orders.Find(id);
_context.Orders.Remove(order);
_context.SaveChanges();
}
}
通过以上步骤,你可以在C# MVC框架中实现业务流程管理。在实际应用中,你可能还需要考虑其他因素,如异常处理、日志记录、安全性等。
