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：

则使用该通用类即可，组件自动调用web.config里面的配置。

using System;using System.Collections.Generic;using System.Linq;using System.Web;using Enyim.Caching;using Enyim.Caching.Configuration;using Enyim.Caching.Memcached;/// 
/// MemberHelper 的摘要说明/// 
public abstract class MemberHelper{    public MemberHelper()    {        //        // TODO: 在此处添加构造函数逻辑        //    }    #region 添加缓存    /// 
    /// 添加缓存(键不存在则添加，存在则替换)    ///

          public static bool AddCache(string key, object value)    {        using (MemcachedClient mc = new MemcachedClient())        {            return mc.Store(StoreMode.Set, key, value);        }    }    #endregion    #region 添加缓存    /// 
    /// 添加缓存(键不存在则添加，存在则替换)    /// 
    /// 键    /// 值    /// 缓存时间(分钟)    /// 
          public static bool AddCache(string key, object value, int minutes)    {         using (MemcachedClient mc = new MemcachedClient())        {            return mc.Store(StoreMode.Set, key, value, DateTime.Now.AddMinutes(minutes));        }    }    #endregion    #region 获取缓存    /// 
    /// 获取缓存    ///

       返回缓存，没有找到则返回null
          public static object GetCache(string key)    {        using (MemcachedClient mc = new MemcachedClient())        {            return mc.Get(key);        }    }    #endregion    #region 是否存在该缓存    /// 
    /// 是否存在该缓存    /// 
    /// 键    /// 
          public static bool IsExists(string key)    {        using (MemcachedClient mc = new MemcachedClient())        {            return mc.Get(key) != null;        }    }    #endregion    #region 删除缓存(如果键不存在，则返回false)    /// 
    /// 删除缓存(如果键不存在，则返回false)    /// 
    /// 键    /// 
      
       成功:true失败:false
          public static bool DelCache(string key)    {        using (MemcachedClient mc = new MemcachedClient())        {            return mc.Remove(key);        }    }    #endregion    #region 清空缓存    /// 
    /// 清空缓存    /// 
    public static void FlushCache()    {        using (MemcachedClient mc = new MemcachedClient())        {            mc.FlushAll();        }    }    #endregion}

二.如果不想在web.config配置，那就使用下面的通用类。
