memcached是一個以key-value的形式緩存數據的緩存系統。經過將數據緩存到內存中，從而提升數據的獲取速度。
memcached以key-value的形式來保存數據，你能夠爲你每一段數據關聯一個key，而後之後能夠經過這個key獲取
這段數據。 html

memcached是一個庫仍是什麼？memcached實際上是一個單獨的網絡服務器程序。它的網絡底層基於libevent，你能夠
將其運行在網絡中的一臺服務器上，經過網絡，在遵循memcached的協議的基礎上與memcached服務器進行通訊。git

1、安裝Memcached服務
1. copy to c:\
2. start -> run -> cmd
3.
C:\memcached -d install -m 500
C:\memcached -d startgithub

2、引用Enyim.Caching.dll緩存

3、配置Config文件服務器

 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>
