如何克服System.ServiceModel.FaultException

Question

在更新我的WCF客戶端的服務引用時（只需單擊Visual Studio 2008中的“更新服務引用”），發生以下錯誤： System.ServiceModel.FaultException ：消息...

我創建了ErrorServiceBehaviour類。 由於為錯誤處理創建了此類行為，因此必須將IErrorHandler實現應用於每個ChannelDispatcher。

public class ErrorServiceBehaviour : Attribute, IServiceBehavior
{
   ...
   public Type FaultType
   {
      get { return _faultType; }
      set { _faultType = value; }
   }

   public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
   {
       foreach (ChannelDispatcher dispatcher in serviceHostBase.ChannelDispatchers)
       {
           dispatcher.ErrorHandlers.Add(new ErrorHandler(_faultType));
       }
   }
}

public class ErrorHandler : IErrorHandler
{
     public ErrorHandler(Type faultType)
     {
        _faultType = faultType;         
     }
     ...
}

后來，我通過將ErrorServiceBehavior屬性應用於我的服務類來使用該行為：

[ErrorServiceBehavior（FaultType = typeof（MyServiceFault））]

public class MyService : IMyService
{
   ...
}

問題是，當我在ApplyDispatchBehavior方法中注釋掉foreach循環時，我根本沒有得到任何錯誤，但這不是出路（因為我希望我的錯誤得到處理）。

下面是我的服務配置：

<system.serviceModel>
    <services>
        <service behaviorConfiguration="DefaultBehavior" name="MyService">
            <endpoint address="" binding="wsHttpBinding" contract="IMyService" bindingConfiguration="NoSecurityBinding"/>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="DefaultBehavior">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <bindings>
        <wsHttpBinding>
            <binding name="NoSecurityBinding" >
                <security mode="None">
                    <transport clientCredentialType="None"/>
                    <message establishSecurityContext="false"/>
                </security>
            </binding>
            <binding name="DefaultBinding" />
        </wsHttpBinding>
    </bindings>
</system.serviceModel>

替換您的代碼並嘗試：

<bindings>
        <wsHttpBinding>
            <binding name="NoSecurityBinding" >
                <security mode="None">
                    <transport clientCredentialType="None"/>
                    <message clientCredentialType="None"/>
                </security>
            </binding>
            <binding name="DefaultBinding" />
        </wsHttpBinding>
    </bindings>
