Question

I am having a program. If an exception occurs, I print the exception message in a cell in my excel sheet. Can I print the FaultException.Detail.ErrorCode and FaultException.Detail.Message?
How can I fetch these two things and print it??
Am posting a sample code

public int CreateTask(int row)
        {
            try
            {
                Console.WriteLine("Invoking CreateTask method");
                Console.WriteLine("-----------------------------------");
                m_taskID = taskClient.CreateTask(m_tInstance);
                Console.WriteLine("Task create successfully:ID=" + m_taskID.ToString());
                Console.WriteLine("-----------------------------------");

                ExcelRecorder(null, row);
            }
            catch (Exception ex)
            {                
                ExcelRecorder(ex.Message, row);
            }
            finally
            {
                GC.Collect();
            }
            return m_taskID;
        } 

How can I modify the ExcelRecorder() method such that FaultException.Detail.ErrorCode and FaultException.Detail.Message can be fetched?

Add this clause above your existing catch clause:

        catch (FaultException<COMException> fex)
        {                
            string msg = fex.Detail.Message;
            string code = fex.Detail.ErrorCode.ToString();
            ExcelRecorder(String.Concat(msg, " - ", code), row);
        }

I presume that you need to catch exception System.ServiceModel.FaultException<TDetail> where TDetail is COMException.
