c# - 客户端配置文件错误

Question

我正在尝试创建一个 AppFabric 缓存客户端，它是一个控制台应用程序。但是在创建 DataCacheFactory 的新实例时收到错误客户端配置文件错误。
连接设置在 App.Config 文件中提供，如 msdn 中所述。 .
代码

static void Main(string[] args)
{
  try
  {
    DataCacheFactory dFact = new DataCacheFactory();
    DataCache myCache = dFact.GetCache("default");

    myCache.Remove("pValue");
    myCache.Add("pValue", "Test Cache Value");
    Console.WriteLine(string.Format("{0}", "Added to cache. Press any key to read...."));
    Console.ReadLine();
    Console.WriteLine(string.Format("{0}", myCache.Get("pValue").ToString()));
    Console.ReadLine();
  }
  catch (Exception Ex)
  {
    throw new System.Exception(Ex.ToString());
  }

}

}
App.Config 文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>

<configSections>
<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>
 <dataCacheClient>
 <hosts>
  <host  name="localhost" cachePort="22233"/>
 </hosts>
 </dataCacheClient>
</configuration>

异常

知道为什么会发生这个错误....谢谢。

您需要将 configSections 元素紧跟在配置元素之后。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!-- Put config sections here -->
  <configSections>
    <!-- Put dataCache client section first -->
    <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" />
    <!-- Then other sections... -->
  </configSections>
