Memcached 之 .NET（C#）实例分析

一：Memcached的安装

step1. 下载memcache(http://jehiah.cz/projects/memcached-win32)的windows稳定版（这里我下载了memcached 1.2.1 for Win32 binaries (Dec 23, 2006) 这个版本），解压放某个盘下面，比如在c:\memcached
step2. 在终端（也即cmd命令界面）下输入 ‘c:\memcached\memcached.exe -d install’ 安装
step3. 再输入： ‘c:\memcached\memcached.exe -d start’ 启动。

          PS: 以后memcached将作为windows的一个服务每次开机时自动启动。这样服务器端已经安装完毕了。

 

二： .NET memcached client library
       下载文件：https://sourceforge.net/projects/memcacheddotnet/ 

       将Commons.dll，ICSharpCode.SharpZipLib.dll，log4net.dll，Memcached.ClientLibrary.dll 等放到bin目录

       引用Memcached.ClientLibrary.dll
