[2.0] Catching Exceptions Thrown via Remoting

[penagate]

Hi all,

I have a MarshalByRefObject which lives on a server and is accessed via a proxy created by Activator.GetObject(). This all works.

I would like to be able to throw an exception in a server-side method and catch it on the client-side.
Is this possible at all? If so, how would I go about doing that? So far when I've tried, I've either had no exception pop up at all, or an "uncaught exception" error on the server-side.


Cheers

Here's how I handle remoting, and the exception thrown in the ProcessFile method gets caught by the calling program.

try
{
	System.Runtime.Remoting.ObjectHandle handle = 
		Activator.CreateInstanceFrom("assemblyFile","typeName");

	IFileProcessor processor = handle.Unwrap();
	processor.ProcessFile("",null);

}
catch (System.Exception ex)
{
	//handle exception
}

I'm still having problems with this.

Here's some code.
Client:

try
{
  this.serverObj.ExceptionTest();
}
catch (Exception ex)
{
  return ex.Message;
}

return null;

Server:

[Serializable]
public class ServerException : Exception, ISerializable
{
  public ServerException(string msg)
    : base(msg) { }
  public ServerException(SerializationInfo info, StreamingContext context)
    : base(info, context) { }
}

// ......

/// <summary>
/// Simulate an error condition
/// </summary>
public void ExceptionTest()
{
  throw new ServerException("Simulated Exception");
}

When I call ExceptionTest from the client, I get an error "ServerException was unhandled by user code" on the server on the throw line in ExceptionTest.
I would have thought that, being marked Serializable, the exception could be propagated across the remoting boundary.

What's the fundamental thing that I'm missing here?
