首先下载windows平台下的memcached，然后安装。安装完之后就是启动memcached服务了，你可以在cmd下用dos命令输入，也可以在计算机管理->服务->memcached->启动.来开启服务.
随后就是在项目中引入相关dll：
Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll
在项目的引用中引入Memcached.ClientLibrary.dll
随后就是编写程序了，在这里创建一个MVC程序:
在Models文件夹中创建一个类:
|
1

6
7
8
9
10
11
12
13

[Serializable]public class VIP
{public string UserName { get; set; }
public int? Vip { get; set; }
public DateTime? VipEndDate { get; set; }
public string Mail { get; set; }
public string QQ { get; set; }
} |
若没有标注为可序列化，则后续运行程序将会报错。
随后创建一个MemcachedHelper类来辅助编程.

public class MemcachedHelper
{public static MemcachedClient mclient;
static MemcachedHelper()
{string[] serverlist = new string[] { "127.0.0.1:11211" };
SockIOPool pool = SockIOPool.GetInstance("First");
pool.SetServers(serverlist);pool.Initialize();mclient = new MemcachedClient();
mclient.PoolName = "First";
mclient.EnableCompression = false;
}public static bool set(string key, object value, DateTime expiry)
{return mclient.Set(key, value, expiry);
}public static object Get(string key)
{return mclient.Get(key);
}} |
最后就是Controller里面的具体实现:

看看实现:
然后退出来，重新点击”实现memcached缓存”
