微软高性能缓存AppFabric（二）使用

原文链接：http://www.cnblogs.com/Qbit/p/6102614.html

从AppFabric 的安装目录中选择两个dll添加到项目中，

默认安装位置：C:\Program Files\用于 Windows Server 的 AppFabric 1.1\

方法一: 使用代码指定配置：

创建缓存对象,在最后 指定的缓存名称处参考：

《微软高性能缓存AppFabric (一) 安装》文章里PowerShell 创建的缓存名称

"使用 New-Cache 命令创建所有必要的命名缓存。"

private DataCache GetCurrentCache()

{

DataCache dCache;

DataCacheServerEndpoint[] servers = new DataCacheServerEndpoint[1];

servers[0] = new DataCacheServerEndpoint

(this.txtAppFabricServerHost.Text,//主机名或IP地址

(int)this.numAppFabricPortNumber.Value);//端口号默认：22233 这里总让我想到网易的表情。。#23 !..
DataCacheFactoryConfiguration factoryConfig = new DataCacheFactoryConfiguration();

factoryConfig.Servers = servers;

var factory = new DataCacheFactory(factoryConfig);

dCache = factory.GetCache(this.txtAppFabricCacheName.Text);//指定缓存名称这里参考

return dCache;

}

方法二：使用配置文件配置缓存

这种配置方法十分灵活，而且程序代码也比较简洁，只需要在配置文件中添加相应的配置即可。

private DataCache GetDefaultCache()

{

    var factory = new DataCacheFactory();

    var dCache = factory.GetCache(this.txtAppFabricCacheName.Text);//缓存名称 

    return dCache;

}

Config文件：

首先需要在configuration 添加一个Section,用来识别我们的配置

   <configSections>
      <!-- required to read the <dataCacheClient> element -->
      <section name="dataCacheClient"
         type="Microsoft.ApplicationServer.Caching.DataCacheClientSection,
            Microsoft.ApplicationServer.Caching.Core, Version=1.0.0.0,
            Culture=neutral, PublicKeyToken=31bf3856ad364e35"
         allowLocation="true"
         allowDefinition="Everywhere"/>
   </configSections>

然后添加缓存配置:

    <dataCacheClient>
      <hosts>
         <host
            name="127.0.0.1"
            cachePort="22233"/>
         <!--<host
            name="CacheServer2"
            cachePort="22233"/>-->
      </hosts>
   </dataCacheClient>

使用AppFabric 进行操作缓存：

//参考文档：https://msdn.microsoft.com/zh-cn/library/ee790846.aspx

// Declare array for cache host(s).

DataCacheServerEndpoint[] servers = new DataCacheServerEndpoint[1];

servers[0] = new DataCacheServerEndpoint("127.0.0.1", 22233);

// Setup the DataCacheFactory configuration.

DataCacheFactoryConfiguration factoryConfig = new DataCacheFactoryConfiguration();

factoryConfig.Servers = servers;

// Create a configured DataCacheFactory object.

DataCacheFactory mycacheFactory = new DataCacheFactory(factoryConfig);

// Get a cache client for the cache "NamedCache1".

DataCache myCache = mycacheFactory.GetCache("NamedCache1");

//add string object to cache with key "Key0"

#region 添加或更新

try

{

myCache.Add("Key0", "object added with Key0");

}

catch (Exception ex)

{

throw;

}

//add or replace string object in cache using key "Key0"

myCache.Put("Key0", "object replaced or added using Key0");

//add or replace object in cache using array notation

myCache["Key0"] = "object replaced or added using Key0";

#endregion

#region 获取

//get string from cache using key "Key0"

string myString1 = (string)myCache.Get("Key0");

//get string from cache using array notation

string myString2 = (string)myCache["Key0"];

#endregion

#region 删除

//remove object in cache using key "Key0"

myCache.Remove("Key0");

//remove object in cache using array notation

myCache["Key0"] = null;

#endregion

return View();
