下载文件 memcached
1.解压缩文件到e:memcached
2.命令行输入 e:memcachedmemcached.exe -d install'
3.命令行输入 e:memcachedmemcached.exe -d start ，该命令启动 Memcached ，默认监听端口为 11211
通过 memcached.exe -h 可以查看其帮助，查看memcache状态，telnet 192.168.0.98 11211。输入stats查询状态
二.NET memcached client library(memcached的.NET客户端类库)
下载memcached的.NET客户端类库，
下载地址：https://sourceforge.net/projects/memcacheddotnet/里面有.net1.1 和 .net2.0的两种版本，
三.应用
1.新建ASP.NET站点，将Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll添加到web引用。
2.新建文件如下
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Memcached.ClientLibrary;
using System.Globalization;
public partial class _Default : System.Web.UI.Page
{
public static string UserName;
public static SockIOPool pool;
public static string PName;
protected void Page_Load(object sender, EventArgs e)
{
//在应用程序启动时运行的代码
char[] separator = { ',' };
string[] serverlist = ConfigurationManager.AppSettings["Memcached.ServerList"].Split(separator);
// initialize the pool for memcache servers
try
{
//pool = SockIOPool.GetInstance();
pool = SockIOPool.GetInstance();
pool.SetServers(serverlist);
pool.InitConnections = 3;
pool.MinConnections = 3;
pool.MaxConnections = 50;
pool.SocketConnectTimeout = 1000;
pool.SocketTimeout = 3000;
pool.MaintenanceSleep = 30;
pool.Failover = true;
pool.Nagle = false;
pool.Initialize();
}
catch (Exception err)
{
throw new Exception(err.Message);
//Response.End();
//这里就可以用Log4Net记录Error啦！
}
//实例化一个客户端
MemcachedClient mc = new MemcachedClient();
mc.EnableCompression = false;
string key = "user_info";//key值
object obj = new object();
if (mc.KeyExists(key)) //测试缓存中是否存在key的值
{
obj = mc.Get(key);
string user2 = obj.ToString();
Response.Write(user2);
mc.Delete(key); //移除缓存中key为test的项目
}
else
{
string userid = "whf";
string NowDate = DateTime.Now.ToShortTimeString();
mc.Add(key, userid+NowDate);
//mc.Set(key, userid); //存储数据到缓存服务器，这里将user这个对象缓存，key 是"user_info1"
Response.Write("没有缓存数据");
}
}
}
或者
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Memcached.ClientLibrary;
using System.Globalization;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//实例化一个客户端
MemcachedClient mc = new MemcachedClient();
mc.EnableCompression = false;
string key = "user_info";//key值
Response.Write(Global.UserName); //Global.asax 设置的变量值
object obj = new object();
if (mc.KeyExists(key)) //测试缓存中是否存在key的值
{
obj = mc.Get(key);
string user2 = obj.ToString();
Response.Write("XX");
}
else
{
string userid = "hf";
mc.Set(key, userid, System.DateTime.Now.AddMinutes(2)); //存储数据到缓存服务器，这里将user这个对象缓存，key 是"user_info1"
Response.Write("没有缓存数据");
}
}
}
