客戶端配置文件中的錯誤

Question

我想創建一個AppFabric緩存客戶端，它是一個控制檯應用程序。但在創建DataCacheFactory的新實例時收到錯誤客戶端配置文件中的錯誤。
連接設置在0123.中描述的App.Config文件中提供。
代碼

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> 

異常

任何I DEA爲什麼發生這種錯誤....謝謝。

您需要將configSections元素立即放置在配置元素之後。

<?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>
