分享下自己编写的Memcached通用类。欢迎大家帮忙指点下哈~
使用的是.NET memcached client library 客户端+Memcached Providers
using System;using System.Collections;using System.Collections.Generic;using System.Text;using Memcached.ClientLibrary;namespace KOC.Common.DataAccess{    /// <summary>    /// Memcache通用类    /// </summary>    public abstract class MemberHelper    {        #region 创建Memcache服务        /// <summary>        /// 创建Memcache服务        /// </summary>        /// <param name="serverlist">IP端口列表</param>        /// <param name="poolName">Socket连接池名称</param>        /// <returns>Memcache客户端代理类</returns>        private static MemcachedClient CreateServer(ArrayList serverlist, string poolName)        {            //初始化memcache服务器池            SockIOPool pool = SockIOPool.GetInstance(poolName);            //设置Memcache池连接点服务器端。            pool.SetServers(serverlist);            pool.Initialize();            //其他参数根据需要进行配置             //创建了一个Memcache客户端的代理类。            MemcachedClient mc = new MemcachedClient();            mc.PoolName = poolName;            mc.EnableCompression = false;//是否压缩             return mc;        }        #endregion        #region 缓存是否存在        /// <summary>        /// 缓存是否存在        /// </summary>        /// <param name="serverlist">IP端口列表</param>        /// <param name="key">键</param>        /// <returns></returns>        public static bool CacheIsExists(ArrayList serverlist, string poolName, string key)        {            MemcachedClient mc = CreateServer(serverlist, poolName);
