.NET平台上的Memcached客户端介绍

.NET平台上的Memcached客户端介绍

上Memcached的官网找.NET的客户端。最后在Codeplex上找到了一个叫Memcached Providers的客户端程序，很小，218K，里面就3个DLL,一个是Memcached Providers本身的DLL，还有一个是Enyim.Caching，Enyim.Caching也是一个.NET平台上的Memcached客户端，最后就是著名的log4net。

Memcached Providers的配置很方便，首先就是在.NET项目中引用上述提到的3个DLL文件，然后就需要修改项目的配置文件，如果是桌面程序，就修改APP.CONFIG，如果是WEB程序，就修改WEB.CONFIG。
首先在configSections节点下增加如下配置

<section name="cacheProvider" type="MemcachedProviders.Cache.CacheProviderSection, MemcachedProviders"
        allowDefinition="MachineToApplication" restartOnExternalChanges="true"/>
<sectionGroup name="enyim.com">
    <section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientSection, Enyim.Caching" />
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>

接着在configuration节点下增加Enyim的配置节点

<enyim.com>
    <memcached>
        <servers>
            <!-- put your own server(s) here-->
            <add address="10.60.0.105" port="19191" />
        </servers>
        <socketPool minPoolSize="10" maxPoolSize="100" connectionTimeout="00:00:10" deadTimeout="00:02:00" />
    </memcached>
</enyim.com>

在configuration节点下增加Memcached Providers的配置节点

<cacheProvider defaultProvider="MemcachedCacheProvider">
    <providers>
        <add name="MemcachedCacheProvider" type="MemcachedProviders.Cache.MemcachedCacheProvider, MemcachedProviders"
                keySuffix="_MySuffix_" defaultExpireTime="2000"/>
    </providers>
</cacheProvider>

最后就是在configuration节点下增加Log4net的配置节点

<log4net>
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}]- %message%newline" />
        </layout>
    </appender>
    <root>
        <priority value="WARN"/>
        <appender-ref ref="ConsoleAppender">
            <filter type="log4net.Filter.LevelRangeFilter">
                <levelMin value="WARN"/>
                <levelMax value="FATAL"/>
            </filter>
        </appender-ref>
    </root>
</log4net>
