C# Net.tcp服务方法和异常处理-WCF

我有一个带有服务方法的WCF服务，它是在自定义代理的帮助下使用net.tcp公开的。我能够使用自定义代理访问我的服务方法，没有任何问题。 但是，在我的一个服务方法中添加异常处理后，代理无法与服务建立连接

工作代码和非工作代码之间的唯一区别在于，非工作代码对a服务方法有适当的异常处理；其中工作版本没有异常处理

到目前为止我做了什么

public void Use(UseServiceDelegate<T> codeBlock, string wcfEndPoint)
        {
            try
            {
                this.proxy = GetChannelFactory(wcfEndPoint).CreateChannel() as IClientChannel;
                if (this.proxy != null)
                {
                    this.proxy.Open(); // Here it fails when I have the exception handling. 
                    codeBlock((T)this.proxy);
                    this.proxy.Close();
                }
            }
            catch (CommunicationException commEx)
            {
                if (this.proxy != null)
                    this.proxy.Abort();

                throw commEx;
            }

        }

 ChannelFactory<T> GetChannelFactory(string wcfEndPoint)
        {
            ChannelFactory<T> channelFactory = null;

            if (!channelPool.TryGetValue(wcfEndPoint, out channelFactory))
            {
                NetTcpBinding binding = new NetTcpBinding();
                binding.MaxReceivedMessageSize = 20000000;
                binding.ReaderQuotas.MaxStringContentLength = 20000000;
                binding.ReaderQuotas.MaxBytesPerRead = 20000000;

                binding.Security.Mode = SecurityMode.None; // I did check it from None to Message/TCP but no luck
                binding.Security.Transport.ClientCredentialType = cpClientCredentialType.Windows;
                binding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
                binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;


                EndpointIdentity epIdentity = EndpointIdentity.CreateUpnIdentity("email@email.come");
                EndpointAddress epAddress = new EndpointAddress(new Uri(wcfEndPoint), epIdentity, new AddressHeaderCollection());

                channelFactory = new ChannelFactory<T>(binding, epAddress);
                channelPool.Add(wcfEndPoint, channelFactory);
            }

            return channelFactory;
        }

我确实试图将安全模式从无更改为消息 例如：

binding.Security.Mode=SecurityMode.Message

我重新启动了诸如

Net.Tcp Listner适配器、Net.Tcp端口共享服务

和

Net.Pipe Listner适配器

等服务

我确实在管理模式下执行了

ServiceModelReg.exe-r

命令

服务合同

[ServiceContract(Namespace = "http://mydom.com/mainrt/subrt")]
public interface IService
{
 [OperationContract]
 [FaultContract(typeof(ServiceException))]
 string CallToServiceMethod(object dataTransferObject);
}

[DataContract(Namespace = "http://mydom.com/mainrt/subrt")]
public class ServiceException
 {
        [DataMember]
        public string ServiceMethodName { get; set; }

        [DataMember]
        public string ErrorMessage { get; set; }

        [DataMember]
        public string ErrorInnerException { get; set; }

        public ServiceException()
        {
            ServiceMethodName = string.Empty;
            ErrorMessage = string.Empty;
            ErrorInnerException = string.Empty;
        }
    }

实施-非工作

public string CallToServiceMethod(object dataTransferObject)
        {
            try
            {
               //code goes here               
            }
            catch (Exception ex)
            {
                throw new FaultException<ServiceException>(new ServiceException()
                                                                    {
                                                                        ErrorInnerException = ex.InnerException.Message,
                                                                        ErrorMessage = ex.Message,
                                                                        ServiceMethodName = "CallToServiceMethod"
                                                                    });
}

public string CallToServiceMethod(object dataTransferObject)
            {
                try
                {
                   //code goes here               
                }
                catch (Exception ex)
                {
                    // Log exception details                
                }
          }

自定义代理和触发器

public void Use(UseServiceDelegate<T> codeBlock, string wcfEndPoint)
        {
            try
            {
                this.proxy = GetChannelFactory(wcfEndPoint).CreateChannel() as IClientChannel;
                if (this.proxy != null)
                {
                    this.proxy.Open(); // Here it fails when I have the exception handling. 
                    codeBlock((T)this.proxy);
                    this.proxy.Close();
                }
            }
            catch (CommunicationException commEx)
            {
                if (this.proxy != null)
                    this.proxy.Abort();

                throw commEx;
            }

        }

 ChannelFactory<T> GetChannelFactory(string wcfEndPoint)
        {
            ChannelFactory<T> channelFactory = null;

            if (!channelPool.TryGetValue(wcfEndPoint, out channelFactory))
            {
                NetTcpBinding binding = new NetTcpBinding();
                binding.MaxReceivedMessageSize = 20000000;
                binding.ReaderQuotas.MaxStringContentLength = 20000000;
                binding.ReaderQuotas.MaxBytesPerRead = 20000000;

                binding.Security.Mode = SecurityMode.None; // I did check it from None to Message/TCP but no luck
                binding.Security.Transport.ClientCredentialType = cpClientCredentialType.Windows;
                binding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
                binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows;


                EndpointIdentity epIdentity = EndpointIdentity.CreateUpnIdentity("email@email.come");
                EndpointAddress epAddress = new EndpointAddress(new Uri(wcfEndPoint), epIdentity, new AddressHeaderCollection());

                channelFactory = new ChannelFactory<T>(binding, epAddress);
                channelPool.Add(wcfEndPoint, channelFactory);
            }

            return channelFactory;
        }

在服务器和客户端同时启用WCF服务跟踪，这将使您了解问题所在。@Morbia，在服务器上启用了跟踪。但不确定客户端如何连接，因为连接是通过客户端的自定义proxy.WCF跟踪建立的，与端点无关，只需在client app.config中添加跟踪配置，它就可以工作了。
