Redis 是一个开源的使用ANSI C 语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value 数据库。Redis的出现，很大程度补偿了memcached这类key/value存储的不足，在部 分场合可以对关系数据库起到很好的补充作用。

本文主要讲述的是如何使用C#语言来进行Redis分布式缓存的程序编写。首先，需要从github下载最新的32/64位安装，解压后根据自己机器的实际情况选择32位或者64位，例如：我机器是64位win7，于是将64bit下所有文件拷贝到D盘根目录下新建文件夹redis中,或者直接下载Redis服务(可以将此服务设置为windows系统服务，下载Redis服务安装软件，安装即可。)，我个人比较喜欢这个。
