1、下载安装号memcached.exe

2、下载memcacheddotnet_clientlib,并将Commons.dll、ICSharpCode.SharpZipLib.dll、log4net.dll、Memcached.ClientLibrary.dll几个文件引用到项目中；

3、完成配置文件，在<configuration>节点下添加节点<configSections>,在<configSection>外添加log4net配置，完整如下：

<configuration>
<!--<appSettings>
<add key="ServerIP" value="http://www.mamicode.com/127.0.0.1"/>
<add key="ServerPort" value="http://www.mamicode.com/11011"/>
</appSettings>-->
<!--<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>-->
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="http://www.mamicode.com/LogFiles/"/>
<param name="AppendToFile" value="http://www.mamicode.com/true"/>
<param name="MaxSizeRollBackups" value="http://www.mamicode.com/10"/>
<param name="StaticLogFileName" value="http://www.mamicode.com/false"/>
<param name="DatePattern" value="http://www.mamicode.com/yyyy-MM-dd".txt""/>
<param name="RollingStyle" value="http://www.mamicode.com/Date"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="http://www.mamicode.com/%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger %ndc - %message%newline"/>
</layout>
</appender>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="http://www.mamicode.com/%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger %ndc - %message%newline" />
</layout>
</appender>
<root>
<level value="http://www.mamicode.com/ALL" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="ConsoleAppender" />
</root>
<logger name="Memcached.ClientLibrary">
<level value="http://www.mamicode.com/WARN" />

</logger>
</log4net>
</configuration>

4、实现代码：

using Memcached.ClientLibrary;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Memcached
{
public static class MemcachedHelper
{
private static MemcachedClient mc;

static MemcachedHelper()
{
try
{
string[] serverList = new string[] { "127.0.0.1:11211" };
SockIOPool sock = SockIOPool.GetInstance();
sock.SetServers(serverList);//添加服务器列表
sock.InitConnections = 3;//设置连接池初始数目
sock.MinConnections = 3;//设置最小连接数目
sock.MaxConnections = 5;//设置最大连接数目
sock.SocketConnectTimeout = 1000;//设置连接的套接字超时。
sock.SocketTimeout = 3000;//设置套接字超时读取
sock.MaintenanceSleep = 30;//设置维护线程运行的睡眠时间。如果设置为0，那么维护线程将不会启动;
sock.Failover = true; //如果为false，对所有创建的套接字关闭Nagle的算法。
sock.Nagle = false;
sock.Initialize();

mc = new MemcachedClient();
}
catch (Exception ex)
{
var exception = ex.Message + ex.StackTrace;
}
}

public static bool SetValue(string key, object value, DateTime expiry)
{
bool isSuccess=false;
try
{
isSuccess = mc.Set(key, value, expiry);

}
catch (Exception ex)
{
var excepion = ex.Message + ex.StackTrace;
}

return isSuccess;
}

public static object GetValue(string key)
{
var result = mc.Get(key);
return result;
}
}
}

代码中实际运用memcached——mycode
