Exception Handling in Dynamics CRM SDK

I am currently developing a simple Dynamics CRM Application which allows the user to create new entities records.

So when an error occurred I get the full stack, but I'm wondering if I could get the attribute name responsible for that error.

As suggested you can use the following handlers to handle common exceptions with CRM:

try
{
    // Write your code here !
}
catch (FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> ex)
{
    Console.WriteLine("The application terminated with an error.");
    Console.WriteLine("Timestamp: {0}", ex.Detail.Timestamp);
    Console.WriteLine("Code: {0}", ex.Detail.ErrorCode);
    Console.WriteLine("Message: {0}", ex.Detail.Message);
    Console.WriteLine("Inner Fault: {0}",
        null == ex.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
}
catch (System.TimeoutException ex)
{
    Console.WriteLine("The application terminated with an error.");
    Console.WriteLine("Message: {0}", ex.Message);
    Console.WriteLine("Stack Trace: {0}", ex.StackTrace);
    Console.WriteLine("Inner Fault: {0}",
        null == ex.InnerException.Message ? "No Inner Fault" : ex.InnerException.Message);
}
catch (System.Exception ex)
{
    Console.WriteLine("The application terminated with an error.");
    Console.WriteLine(ex.Message);

    // Display the details of the inner exception.
    if (ex.InnerException != null)
    {
        Console.WriteLine(ex.InnerException.Message);

        FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> fe = ex.InnerException
            as FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>;
        if (fe != null)
        {
            Console.WriteLine("Timestamp: {0}", fe.Detail.Timestamp);
            Console.WriteLine("Code: {0}", fe.Detail.ErrorCode);
            Console.WriteLine("Message: {0}", fe.Detail.Message);
            Console.WriteLine("Trace: {0}", fe.Detail.TraceText);
            Console.WriteLine("Inner Fault: {0}",
                null == fe.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
        }
    }
}

This can also be written and used as

private T TryCatch<T>(Func<T> action)
        {
            try
            {
                return action();
            }
            catch (FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> ex)
            {
                Console.WriteLine("The application terminated with an error.");
                Console.WriteLine("Timestamp: {0}", ex.Detail.Timestamp);
                Console.WriteLine("Code: {0}", ex.Detail.ErrorCode);
                Console.WriteLine("Message: {0}", ex.Detail.Message);
                Console.WriteLine("Inner Fault: {0}",
                    null == ex.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
            }
            catch (System.TimeoutException ex)
            {
                Console.WriteLine("The application terminated with an error.");
                Console.WriteLine("Message: {0}", ex.Message);
                Console.WriteLine("Stack Trace: {0}", ex.StackTrace);
                Console.WriteLine("Inner Fault: {0}",
                    null == ex.InnerException.Message ? "No Inner Fault" : ex.InnerException.Message);
            }
            catch (System.Exception ex)
            {
                Console.WriteLine("The application terminated with an error.");
                Console.WriteLine(ex.Message);

                // Display the details of the inner exception.
                if (ex.InnerException != null)
                {
                    Console.WriteLine(ex.InnerException.Message);

                    FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> fe = ex.InnerException
                        as FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>;
                    if (fe != null)
                    {
                        Console.WriteLine("Timestamp: {0}", fe.Detail.Timestamp);
                        Console.WriteLine("Code: {0}", fe.Detail.ErrorCode);
                        Console.WriteLine("Message: {0}", fe.Detail.Message);
                        Console.WriteLine("Trace: {0}", fe.Detail.TraceText);
                        Console.WriteLine("Inner Fault: {0}",
                            null == fe.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
                    }
                }
            }

            //return
            return default(T);
        }

Where you just have to call:

return TryCatch<int>(()=> {
    //write code here
    return 5;
});

and don't have to write the catch block everywhere.

We can throw an exception and display a message.

throw new InvalidPluginExecutionException("Message here....");

When you want to avoid emitting full stack traces for known CRM platform errors, you can catch errors of type FaultException<OrganizationServiceFault> and handle them in an appropriate way, like this:

try
{
    service.Create(entity);
}
catch (FaultException<OrganizationServiceFault> ex)
{
   switch (ex.Detail.ErrorCode)
   {
       case 0x80041103: // QueryBuilderNoAttribute
          Console.WriteLine(ex.Detail.Message);
          // Specific error handling goes here...
          return;

       default:
          throw;
   }
}

The platform error codes are documented and can be looked up on MSDN.
