一.如果用官方提供的方法，在web.config里面配置好了各个参数和服务器IP。如下图：
<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="enyim.com">
<section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<enyim.com>
<memcached protocol="Text">
<servers>
<add address="127.0.0.1" port="11211" />
<add address="127.0.0.1" port="11212" />
<add address="127.0.0.1" port="11213" />
<add address="127.0.0.1" port="11214" />
</servers>
<socketPool minPoolSize="10" maxPoolSize="100" connectionTimeout="00:00:05" deadTimeout="00:02:00" />
</memcached>
</enyim.com>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
</configuration>
则使用该通用类即可，组件自动调用web.config里面的配置。

二.如果不想在web.config配置，那就使用下面的通用类。

using System.Linq;
using System.Net;
using System.Web;

} #region 创建Memcache客户端
/// <summary>
/// 创建Memcache客户端
/// </summary>
/// <param name="serverList">服务列表</param>
/// <returns></returns>
private static MemcachedClient CreateServer(List<IPEndPoint> serverList)
{
MemcachedClientConfiguration config = new MemcachedClientConfiguration();//创建配置参数
for (int i = 0; i < serverList.Count; i++)
{
config.Servers.Add(new System.Net.IPEndPoint(IPAddress.Parse(serverList[i].Address.ToString()), serverList[i].Port));//增加服务节点
}
config.Protocol = MemcachedProtocol.Text;
config.Authentication.Type = typeof(PlainTextAuthenticator);//设置验证模式
config.Authentication.Parameters["userName"] = "uid";//用户名参数
config.Authentication.Parameters["password"] = "pwd";//密码参数
MemcachedClient mac = new MemcachedClient(config);//创建客户端
return mac;
}
