.Net Memcached缓存用法
memcached是一个以key-value的形式缓存数据的缓存系统。通过将数据缓存到内存中，从而提高数据的获取速度。memcached以key-value的形式来保存数据，你可以为你每一段数据关联一个key，然后以后可以通过这个key获取
这段数据。
memcached是一个库还是什么？memcached其实是一个单独的网络服务器程序。它的网络底层基于libevent，你可以
将其运行在网络中的一台服务器上，通过网络，在遵循memcached的协议的基础上与memcached服务器进行通信。
一、安装Memcached服务
1. copy to c:\
2. start -> run -> cmd
3.
C:\memcached -d install -m 500
C:\memcached -d start
二、引用Enyim.Caching.dll
三、配置Config文件
1 <?xml version="1.0" encoding="utf-8" ?>
2 <configuration>
3 <configSections>
4 <sectionGroup name="enyim.com">
5 <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
6 </sectionGroup>
7 <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching"/>
8 </configSections>
9
10 <enyim.com>
11 <memcached configSource="ConfigFiles\enyim.com.config"/>
12 </enyim.com>
13 <memcached configSource="ConfigFiles\memcached.config"/>
14
15 <startup>
16 <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
17 </startup>
18 </configuration>
