Hi Bill,

Please try define the CustomFault(MathFault in this example) as a data contract rather than Operation Contract, like:

[DataContract]
public class MathFault
{    
    //...
}

At the client side:

  static void Main(string[] args)
        {
            ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
            try
            {
                int value1 = 22;
                int value2 = 0;
                int result = client.Divide(value1, value2);
                Console.WriteLine("Divide({0},{1}) = {2}", value1, value2, result);
                client.Close();
            }
            catch (FaultException<MathFault> e)
            {
                Console.WriteLine("FaultException<MathFault>: Math fault while doing " + e.Detail.Operation + ". Problem: " + e.Detail.ProblemType);
                client.Abort();
                Console.ReadLine();
            }
        }

Haixia, I very much appreciate your help :)

I modified my code, but am unsure how to throw the FaultException.

I have the following set up now on my service now:

I'm referencing a class that contains the DataContract as partially seen below. I think I would only need the applicationID and logeventType as the FaultException would seem to carry over the other properties I have listed. Please let me know if that is true.

namespace Ryder.Enterprise.DataTransferObjects
{
	[Serializable, DataContract(Name = "LogEventArgs", Namespace = "http://www.Ryder.com/SOA/DataContracts/2014/02/17")]
	public class LogEventArgs
	{
		private string applicationID;
		private string method;
		private LogEventTypeEnum logEventType;
		private string exceptionMessage;
		private string innerExceptionMessage;
		private string stackTrace;
		private string source;
		
		[DataMember(Name = "ApplicationID")]
		public string ApplicationID
		{
			get
			{
				return applicationID;
			}
			set
			{
				applicationID = value;
			}
		}
.
.
.

This is the method where I want to throw the FaultException. Syntactically, how would that look? Not sure how to place it in the Catch block or if even the Catch block is correct.

public bool UpdateSpotCheckInventory(SpotCheck transferObject)
		{
			bool blnUpdated = false;

			try
			{
				blnUpdated = SpotCheckCollectionGateway.UpdateData(transferObject);
				LogMessage.WriteEventLog("SpotCheck records updated successfully", "Ryder.ShopProcessService.SOA", 3, null);

				return blnUpdated;
			}
			catch (Exception ex)
			{
				//throw fault exception here on service
				return blnUpdated;
			}
		}

This is what I have on my client now. When the FaultException gets hit, it is transmitted back to the calling service and they would receive the exception message with the appropriate properties including the ex.Message, stacktrace, method, etc?

catch (FaultException<LogEventArgs> ex)
			{					ex.Detail.ApplicationID = "ShopProcessService";
				ex.Detail.LogEventType = LogEventTypeEnum.Error;
				serviceClient.Abort();
			}

Finally, what would a Catch block look like on the receing end of getting the FaultException back from a service?
