WCF异常处理错误

请说明确切的问题是什么 my

GlobalErrorHandlerBehaviurattribute

类

using System;
using System.Collections.Generic;
using System.Linq;`enter code here`
using System.Text;
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
namespace HelloService

{
  public class GlobalErrorHandlerBehavoiurAttribute:Attribute,IServiceBehavior
    {
      private readonly Type errorhanderType;
      public GlobalErrorHandlerBehavoiurAttribute(Type errorhanderType)
      {
          this.errorhanderType = errorhanderType;
      }
        public void AddBindingParameters(ServiceDescription serviceDescription, 

System.ServiceModel.ServiceHostBase serviceHostBase, 
System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, 
System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
        {

        }
        public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
        {
            IErrorHandler handler = (IErrorHandler)Activator.CreateInstance(this.errorhanderType);
            foreach (ChannelDispatcherBase ChannelDispatcherBase in serviceHostBase.ChannelDispatchers)
            {
                ChannelDispatcher channeldispatcher = ChannelDispatcherBase as ChannelDispatcher;
                if (channeldispatcher != null)
                {
                    channeldispatcher.ErrorHandlers.Add(handler);
                }                                         
            }
        }

        public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
        {

        }
    }
}

我的服务实现代码

public int Divide(int num,int dem)
    {
        //if (dem == 0)
        //{
        //    throw new FaultException("Dem can not be zero", new FaultCode("DivideByZero"));
        //}
        //try
        //{
            return num / dem;

    enter code here
        //}
        //catch (DivideByZeroException ex)
        //{
        //    DivideByZeroFault dividebyzero = new DivideByZeroFault();
        //    dividebyzero.Error = ex.Message;
        //    dividebyzero.Details = "Deno can not be greater than zero";
        //    throw new FaultException<DivideByZeroFault>(dividebyzero);
        //}
    }

当我们通过10/0时，它将显示

GlobalErrorHandler

类的“发生一般错误”消息。但它并没有显示出来。我已经在

GlobalErrorHandler

类中放置了braekpoints，但它不会在

GlobalErrorHandler

类中运行。

启用在抛出异常时中断。关掉“只是我的代码”，有点混乱。请告诉我具体要做什么。菜单->调试->异常。。。选中此框可在引发异常时中断。菜单->工具->选项。。。在LHS上选择“调试”，在RHS上找到“仅启用我的代码”并取消检查。我也打开了服务和应用程序的异常抛出。但问题仍然存在。当然它仍然存在！但是现在你可以看到它抛出的点了。

    {
        //if (dem == 0)
        //{

        //}
        //try
        //{
            return num / dem;

    enter code here
