一、下载redis安装文件redis-2.4.6-setup-32-bit.exe。这里一个32位的，本人现在用的XP系统，貌似影响不是很大。详情附件。
安装好之后在服务里面启动
二、用vs新建一个小程序，引用4个redis需要的dll文件，详情附件。
三、建一个RedisHelper类,引用4个dll。
public class RedisHelper : IDisposable
{
private static string strRedis = System.Configuration.ConfigurationManager.AppSettings["RedisPath"].ToString();//web.config中配置我本机的一个IP
public RedisClient Redis = new RedisClient(strRedis, 6379);
//缓存池
PooledRedisClientManager prcm = new PooledRedisClientManager();
//默认缓存过期时间单位秒
public int secondsTimeOut = 30 * 60;
/// <summary>
/// 缓冲池
/// </summary>
/// <param name="readWriteHosts"></param>
/// <param name="readOnlyHosts"></param>
/// <returns></returns>
public static PooledRedisClientManager CreateManager(
string[] readWriteHosts, string[] readOnlyHosts)
{
return new PooledRedisClientManager(readWriteHosts, readOnlyHosts,
new RedisClientManagerConfig
{
MaxWritePoolSize = readWriteHosts.Length * 5,
MaxReadPoolSize = readOnlyHosts.Length * 5,
AutoStart = true,
});
}
/// <summary>
/// 构造函数
/// </summary>
/// <param name="OpenPooledRedis">是否开启缓冲池</param>
public RedisHelper(bool OpenPooledRedis = false)
{
if (OpenPooledRedis)
{
prcm = CreateManager(new string[] { strRedis + ":6379" }, new string[] { strRedis + ":6379" });
Redis = prcm.GetClient() as RedisClient;
}
}
#region Key/Value存储
/// <summary>
/// 设置缓存
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="key">缓存建</param>
/// <param name="t">缓存值</param>
/// <param name="timeout">过期时间，单位秒,-1：不过期，0：默认过期时间</param>
/// <returns></returns>
public bool Set<T>(string key, T t, int timeout = 0)
{
if (timeout >= 0)
{
if (timeout > 0)
{
secondsTimeOut = timeout;
}
Redis.Expire(key, secondsTimeOut);
}
return Redis.Add<T>(key, t);
}
/// <summary>

/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="key"></param>
/// <returns></returns>
public T Get<T>(string key)
{
return Redis.Get<T>(key);
}
/// <summary>
/// 移除整个类型的key
/// </summary>
/// <param name="key"></param>
/// <returns></returns>
public bool Remove(string key)
{
return Redis.Remove(key);
}
/// <summary>
/// key是否存在(0:不存在；1;存在)
/// </summary>
/// <param name="key"></param>
/// <returns></returns>
public int IsExists(string key)
{
return Convert.ToInt32(Redis.Exists(key));
}
public bool Add<T>(string key, T t, int timeout)
{
if (timeout >= 0)
{
if (timeout > 0)
{
secondsTimeOut = timeout;
}
Redis.Expire(key, secondsTimeOut);
}
return Redis.Add<T>(key, t);
}
#endregion
/// <summary>
/// 释放资源
/// </summary>
public void Dispose()
{
if (Redis != null)
{
Redis.Dispose();
Redis = null;
}
GC.Collect();
}
#region Hash的方法
/// <summary>
/// 判断某个数据是否已经被缓存
/// </summary>
public bool Exist<T>(string hashId, string key)
{
return Redis.HashContainsEntry(hashId, key);
}
/// <summary>
/// 存储数据到hash表
/// </summary>
public bool Set1<T>(string hashId, string key, string value)
{
return Redis.SetEntryInHash(hashId, key, value);
}
/// <summary>
/// 移除hash中的某值
/// </summary>
public bool Remove(string hashId, string key)
{
return Redis.RemoveEntryFromHash(hashId, key);
}
/// <summary>

/// </summary>
public string Get1<T>(string hashId, string key)
{
return Redis.GetValueFromHash(hashId, key);
}
/// <summary>
/// 获取整个hash的数据
/// </summary>
public string GetAll1(string hashId)
{
string result = "";
var list = Redis.GetHashValues(hashId);
if (list != null && list.Count > 0)
{
for (int i = 0; i < list.Count; i++)
{
var aa = list[i];
result += aa + ",";
}
result = result.Trim(',');
}
return result;
}
/// <summary>
/// 设置缓存过期
/// </summary>
public void SetExpire(string key, DateTime datetime)
{
Redis.ExpireEntryAt(key, datetime);
}
#endregion
}四、再建一个ashx一般处理程序。
public class UserTest
{
public int userId { get; set; }
public string userName { get; set; }
public string userPwd { get; set; }
public int userAge { get; set; }
}
public class RedisSelectTset1 : IHttpHandler
{
public void Proce***equest(HttpContext context)
{
context.Response.ContentType = "text/plain";
RedisHelper redis = new RedisHelper(true);
UserTest user = null;
for (int i = 0; i < 10; i++)
{
user = new UserTest() { userId = i, userName = "admin" + i, userPwd = "123456", userAge = 20 + i };
var value = JsonSerializer.SerializeToString<UserTest>(user);//序列化json格式
redis.Set1<byte>("userHash", "user_Id" + i, value);//第一插入返回Ture，覆盖重复的返回Flash
}
string getAll = redis.GetAll1("userHash");//获得所有的数据
DateTime dateTime = Convert.ToDateTime("2099-12-31 00:00:00");//设置缓存过期时间
redis.SetExpire("userHash", dateTime);
context.Response.Write(getAll);
}
public bool IsReusable
{
get
{
return false;
}
}
}运行页面之后如何显示：
之后可以在cmd中打开客户端链接：hgetall userHash 根据key取出所有的value
就能在你的内存中看到你刚刚运行的页面保存的数据
根据redis的命令，可以去除单条数据，如何下图：
关于redis跟多有趣的东西，楼主也在尝试。
