WCF - 遠程服務器返回了意外的響應：（400）錯誤的請求

我在將byte []傳遞給WCF時出現此錯誤。有人可以解決這個錯誤？WCF - 遠程服務器返回了意外的響應：（400）錯誤的請求

配置在提供服務（web.config中）在WPF應用程序（app.config）中

<configuration> 
    <system.web>

如果您發佈代碼，XML或數據樣本， **請**在文本編輯器中突出顯示這些行，然後單擊編輯器工具欄上的「代碼示例」按鈕（{}），以便對其進行精確格式化和語法突出顯示！ – 2011-02-15 08:03:28

不知道您的服務合同和所需的所有細節 - 我只能猜測。

令我震驚的是，您的服務器端配置不包含<service>的任何配置。

的規則是這樣的：

在服務器端，你需要一個<services>標籤在你的配置，其中包含任意數量的<service>標籤，它定義了服務器上的每個服務。每個<service>標籤又可以包含任意數量的<endpoint>標籤來定義客戶上的一個或多個服務端點
，您有一個或多個<client>條目，每個條目中都包含一個<endpoint>，它定義了服務地址您的客戶端連接到

所以，你的服務器端的配置應該是這個樣子：

<system.serviceModel> 
    <bindings> 
     <basicHttpBinding> 
      <binding name="NewBinding0" ....... /> 
     </basicHttpBinding> 
     ..... 
    </bindings> 
    <services> 
     <service name="YourNamespace.YourService" 
       behaviorConfiguration="Default" > 
      <endpoint name="BasicEndpoint" 
       address="http://localhost:5757/Services" 
       binding="basicHttpBinding" 
       bindingConfiguration="NewBinding0" 
       contract="YourNamespace.IYourServiceContract" /> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior name="Default"> 
      <serviceMetadata httpGetEnabled="true"/> 
      <serviceDebug includeExceptionDetailInFaults="false"/> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    ...... 
</system.serviceModel>

您的客戶端配置看起來很好 - 除了當然，您必須將您的服務器的服務所在的地址放入address=屬性 - 通常不是localhost
