首先具备的条件就是你能够使用Memcached：
1，你有一台缓存服务器能够配置linux+Memcached。
2，你需要保存的数据量不是很大单机配置windows版的Memcached。点击下载
其次你要找一个.net调用Memcached的api类：
Memcached的主站有推荐，我现在用的是Memcached.ClientLibrary.dll。点击下载
然后你找篇配置文件配起来就可以测试使用了。
如果想使用我的类，具体方法参照我以前一篇文章，不过我已经将MyCache类扩展可以使用Memcached。
配置文件需要增加几个参数
<add key="default_buffminutes" value="45"/>
<add key="Memcached" value="true"/>
<add key="MemServer" value="192.168.1.160:11211"/>
MyCache.cs是操作类，DelegateLists是委托方法函数，跟你需要的函数来定义。
