Question

更新我的WCF客户端的服务引用时（只需单击Visual Studio 2008中的“更新服务引用”），就会出现以下错误： System.ServiceModel.FaultException ：消息...

我创建了ErrorServiceBehaviour类。因为为错误处理创建了这样的行为，所以必须将IErrorHandler实现应用于每个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;         
     }
     ...
}

稍后，我通过将ErrorServiceBehavior属性应用于我的服务类来使用该行为：

[ErrorServiceBehavior（FaultType = typeof（MyServiceFault））]

public class MyService : IMyService
{
   ...
}

问题是，当我在ApplyDispatchBehavior方法中注释掉foreach循环时，我根本没有得到任何错误，但这不是出路（因为我希望我的错误得到处理）。

下面是我的服务配置：

<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>

替换您的代码并尝试：

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