[WCF] Fault Contract

在服务端定义异常：

using System;

using System.ServiceModel;

using System.Runtime.Serialization;

using System.ServiceModel.Channels;

 

namespace FaultExceptions

{

 

    [ServiceContract()]

    public interface IFaultExceptionService

    {

        [OperationContract]

        [FaultContract(typeof(InvalidOperationException))]

        void ThrowSimpleFault();

 

        [OperationContract]

        [FaultContract(typeof(InvalidOperationException))]

        void ThrowMessageFault();

 

        [OperationContract()]

        [FaultContract(typeof(InvalidOperationException))]

        void ThrowFaultException();

 

    }

 

    public class FaultExceptionService : IFaultExceptionService

    {

        #region IService Members

 

        public void ThrowSimpleFault()

        {

            throw new FaultException("An invalid operation has occurred.");

        }

 

        public void ThrowMessageFault()

        {

            InvalidOperationException error = new InvalidOperationException("An invalid operation has occurred.");

 

            MessageFault mfault = MessageFault.CreateFault(new FaultCode("Server", new FaultCode(String.Format("Server.{0}", error.GetType().Name))), new FaultReason(error.Message), error);

 

            FaultException fe = FaultException.CreateFault(mfault, typeof(InvalidOperationException));

 

            throw fe;

        }

 

        public void ThrowFaultException()

        {

            FaultException<InvalidOperationException> fe = new FaultException<InvalidOperationException>(new InvalidOperationException("An invalid operation has occured."), "Invalid operation.", new FaultCode("Server", new FaultCode(String.Format("Server.{0}", typeof(NotImplementedException)))));

            throw fe;

        }

 

        #endregion

    }

}

客户端接收异常：

 

localhost.FaultExceptionServiceClient proxy = new Client.localhost.FaultExceptionServiceClient();

 

            try

            {

                Console.ForegroundColor = ConsoleColor.Yellow;

                Console.WriteLine("Calling proxy.ThrowSimpleFault()");

                Console.WriteLine("");

                Console.ResetColor();

 

                proxy.ThrowSimpleFault();

 

            }

            catch (FaultException fe)

            {

 

                Console.WriteLine(fe.GetType().ToString());

                Console.WriteLine("ERROR: {0}", fe.Message);

 

            }

            catch (Exception ex)

            {

 

                Console.WriteLine(ex.GetType().ToString());

                Console.WriteLine("ERROR: {0}", ex.Message);

           }
