Memcached帮助类

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

"1.0"?>

     
     "enyim.com">
      
"memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
    
    
"log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> 
  
  
    "Text">
       
        "127.0.0.1" port="11211" />
        "127.0.0.1" port="11212" />
        "127.0.0.1" port="11213" />
        "127.0.0.1" port="11214" />
      
      "10" maxPoolSize="100" connectionTimeout="00:00:05" deadTimeout="00:02:00" />
    
   
  
    "true" targetFramework="4.0"/>
  

则使用该通用类即可，组件自动调用web.config里面的配置。

    }

        {
            return mc.Get(key);
        }
    }
    #endregion

    }

        using (MemcachedClient mc = new MemcachedClient())
        {
            return mc.Remove(key);
        }
    }
    #endregion
    #region 清空缓存
    /// 

    /// 清空缓存
    ///

    {
        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。

        //
    }
    #region 创建Memcache客户端
    /// 

    /// 创建Memcache客户端
    /// 
    /// 服务列表
    /// 
    private static MemcachedClient CreateServer(List 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;
    }
