我有一个成功工作的WCF正在被.net 4中的web客户端使用,但是当尝试将IErrorhandler作为全局错误记录器设置为捕获所有我的所有服务方法时,事情都快速失败 – 主要是与web.config部分！请帮忙.

这三个服务是：IReport,IServiceCustomer,IServiceUser

在一个名为MyErrorClass.cs的单独类中实现了IErrorHandler,如下所示：

namespace CustomerWcfService
{
public class WcfErrorHandler : IErrorHandler
{
   /// <summary>
    /// Enables the creation of a custom <see cref="T:System.ServiceModel.FaultException`1"/> that is returned from an exception in the course of a service method.
    /// </summary>
    /// <param name="error">The <see cref="T:System.Exception"/> object thrown in the course of the service operation.</param><param name="version">The SOAP version of the message.</param><param name="fault">The <see cref="T:System.ServiceModel.Channels.Message"/> object that is returned to the client,or service,in the duplex case.</param>
    public void ProvideFault(Exception error,MessageVersion version,ref Message fault)
    {
        // can create custom error messages here
    }

    /// <summary>
    /// Enables error-related processing and returns a value that indicates whether the dispatcher aborts the session and the instance context in certain cases. 
    /// </summary>
    /// <returns>
    /// true if  should not abort the session (if there is one) and instance context if the instance context is not <see cref="F:System.ServiceModel.InstanceContextMode.Single"/>; otherwise,false. The default is false.
    /// </returns>
    /// <param name="error">The exception thrown during processing.</param>
    public bool HandleError(Exception error)
    {
        // log error to database using legacy error handler
        ErrorHandler.LogError(error);

        // Let the other ErrorHandler do their jobs
        return true;
    }
}

public class WcfErrorServiceBehavIoUr : IServiceBehavior
{
    /// <summary>
    /// Provides the ability to inspect the service host and the service description to confirm that the service can run successfully.
    /// </summary>
    /// <param name="serviceDescription">The service description.</param><param name="serviceHostBase">The service host that is currently being constructed.</param>
    public void Validate(ServiceDescription serviceDescription,ServiceHostBase serviceHostBase)
    {   }

    /// <summary>
    /// Provides the ability to pass custom data to binding elements to support the contract implementation.
    /// </summary>
    /// <param name="serviceDescription">The service description of the service.</param><param name="serviceHostBase">The host of the service.</param><param name="endpoints">The service endpoints.</param><param name="bindingParameters">Custom objects to which binding elements have access.</param>
    public void AddBindingParameters(ServiceDescription serviceDescription,ServiceHostBase serviceHostBase,Collection<ServiceEndpoint> endpoints,BindingParameterCollection bindingParameters)
    {   }

    /// <summary>
    /// Provides the ability to change run-time property values or insert custom extension objects such as error handlers,message or parameter interceptors,security extensions,and other custom extension objects.
    /// </summary>
    /// <param name="serviceDescription">The service description.</param><param name="serviceHostBase">The host that is currently being built.</param>
    public void ApplyDispatchBehavior(ServiceDescription serviceDescription,ServiceHostBase serviceHostBase)
    {
        var handler = new WcfErrorHandler();
        foreach (ChannelDispatcher dispatcher in serviceHostBase.ChannelDispatchers)
        {
            dispatcher.ErrorHandlers.Add(handler);
        }
    }
}

public class WcfErrorHandlerBehavIoUr : BehaviorExtensionElement
{
    /// <summary>
    /// Creates a behavior extension based on the current configuration settings.
    /// </summary>
    /// <returns>
    /// The behavior extension.
    /// </returns>
    protected override object CreateBehavior()  {   return new WcfErrorServiceBehavIoUr();  }

    /// <summary>
    /// Gets the type of behavior.
    /// </summary>
    /// <returns>
    /// A <see cref="T:System.Type"/>.
    /// </returns>
    public override Type BehaviorType   {   get { return typeof (WcfErrorServiceBehavIoUr); }   }
}
}

web.config应该是什么样的,因为我已经尝试了来自各种教程和网络上的答案的百万组合,但不能使其工作！这是当我不涉及IErrorHandler时,web.config的原始工作提取是如何看的

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing @R_403_338@data information,set the value below to false and remove the @R_403_338@data endpoint above before deployment -->
          <service@R_403_338@data httpGetEnabled="true" />
          <!-- To receive exception details in faults for debugging purposes,set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer>

请允许有人发送这个WCF noob修正的web.config请求,因为我一直在删除,再次尝试,得到没有在哪里(我已经失去了这么多天):(
