安装

Memcached服务器端的安装 (此处将其作为系统服务安装)

  下载文件:​​memcached 1.2.1 for Win32 binaries (Dec 23, 2006)​​ 

   1 解压缩文件到c:\memcached

   2 命令行输入 'c:\memcached\memcached.exe -d install' 

   3 命令行输入 'c:\memcached\memcached.exe -d start' ,该命令启动 Memcached ,默认监听端口为 11211

  通过 memcached.exe -h 可以查看其帮助


系统中会添加下面的服务


二   .NET memcached client library

   下载文件:​​https://sourceforge.net/projects/memcacheddotnet/​

里面有.net1.1 和 .net2.0的两种版本 还有一个不错的例子。

版本更新很慢,在.Net 的开发技术中十分少用,首微软的开发解决方案上面不赞成此种共享内存方式。
