.NET（C#）下操作Memcahed

一：Memcached的安装

**step1**. 下载memcache([http://www.runoob.com/memcached/window-install-memcached.html][http_www.runoob.com_memcached_window-install-memcached.html])的windows稳定版，解压放某个盘下面，比如在c:\\memcached  
**step2**. 在终端（也即cmd命令界面）下输入 ‘c:\\memcached\\memcached.exe -d install’ 安装  
**step3**. 再输入： ‘c:\\memcached\\memcached.exe -d start’ 启动。

PS: 以后memcached将作为windows的一个服务每次开机时自动启动。这样服务器端已经安装完毕了。

二： .NET memcached client library  
下载文件：[https://sourceforge.net/projects/memcacheddotnet/][https_sourceforge.net_projects_memcacheddotnet]

将Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll 等放到bin目录
       引用Memcached.ClientLibrary.dll

程序

using System;
 using System.Collections;
 using Memcached.ClientLibrary;
 using System.Text;
 
 namespace Memcache
 {
 public partial class _Default : System.Web.UI.Page
 {
 protected void Page_Load(object sender, EventArgs e)
 {
 if (!IsPostBack)
 {
 if (Request["action"] == "clear")
 this.clear();
 else
 this.test();
 }
 }
 
 public void clear()
 {
 string[] servers = { "192.168.1.113:11211", "192.168.202.128:11211" };
 
 //初始化池
 SockIOPool pool = SockIOPool.GetInstance();
 pool.SetServers(servers);
 pool.InitConnections = 3;
 pool.MinConnections = 3;
 pool.MaxConnections = 5;
 pool.SocketConnectTimeout = 1000;
 pool.SocketTimeout = 3000;
 pool.MaintenanceSleep = 30;
 pool.Failover = true;
 pool.Nagle = false;
 pool.Initialize();
 MemcachedClient mc = new Memcached.ClientLibrary.MemcachedClient();
 mc.EnableCompression = false;
 mc.Delete("cache");
 mc.Delete("endCache");
 Response.Write("清空缓存成功");
 }
 
 
 public void test()
 {
 //分布Memcachedf服务IP 端口
 string[] servers = { "192.168.1.113:11211", "192.168.202.128:11211" };
 
 //初始化池
 SockIOPool pool = SockIOPool.GetInstance();
 pool.SetServers(servers);
 pool.InitConnections = 3;
 pool.MinConnections = 3;
 pool.MaxConnections = 5;
 pool.SocketConnectTimeout = 1000;
 pool.SocketTimeout = 3000;
 pool.MaintenanceSleep = 30;
 pool.Failover = true;
 pool.Nagle = false;
 pool.Initialize();
 //客户端实例
 MemcachedClient mc = new Memcached.ClientLibrary.MemcachedClient();
 mc.EnableCompression = false;
 StringBuilder sb = new StringBuilder();
 //写入缓存
 sb.AppendLine("写入缓存测试：");
 sb.AppendLine(" _______________________________________ ");
 if (mc.KeyExists("cache"))
 {
 sb.AppendLine("缓存cache已存在");
 }
 else
 {
 mc.Set("cache", "写入缓存时间：" +DateTime.Now.ToString());
 sb.AppendLine("缓存已成功写入到cache");
 }
 sb.AppendLine(" _______________________________________ ");
 sb.AppendLine("读取缓存内容如下： ");
 sb.AppendLine(mc.Get("cache").ToString());
 
 //测试缓存过期
 sb.AppendLine(" _______________________________________ ");
 if (mc.KeyExists("endCache"))
 {
 sb.AppendLine("缓存endCache已存在，过期时间为：" + mc.Get("endCache").ToString());
 }
 else
 {
 mc.Set("endCache", DateTime.Now.AddMinutes(1).ToString(), DateTime.Now.AddMinutes(1));
 sb.AppendLine("缓存已更新写入到endCache，写入时间：" + DateTime.Now.ToString() +" 过期时间：" + DateTime.Now.AddMinutes(1).ToString());
 }
 
 //分析缓存状态
 Hashtable ht = mc.Stats();
 sb.AppendLine(" _______________________________________ ");
 sb.AppendLine("Memcached Stats:");
 sb.AppendLine(" _______________________________________ ");
 foreach (DictionaryEntry de in ht)
 {
 Hashtable info = (Hashtable)de.Value;
 foreach (DictionaryEntry de2 in info)
 {
 sb.AppendLine(de2.Key.ToString() + ":    " + de2.Value.ToString() + " ");
 }
 }
 Response.Write(sb.ToString());
 }
 }
 }
