Handling Exceptions from another thread

[Fayu]

I am having some issue handling an exception thrown in another thread in my UI. My question is how can I handle exceptions from another thread without syncronized the threads in the UI. I would prefer to sync the threads in the class where the method is called. Any suggestions? Here is my code: Localized fields

Test t = new Test();

Method that throws the exception

public class Test
{
public void DoSomething()
{
throw new MyCustomException(this,EventArgs.Empty);
}
}

The exception

public class MyCustomException : Exception
{
...
}

This is in the UI. Not multi-threaded

 void CallException()
 {
      try
      {
           t.DoSomething();
      }
      catch(MyCustomException ex)
      {
           lblMessage.Text = "error";
      }
 }

This is also in the UI. Multi-threaded

 void CallExceptionASync()
 {
      Thread thrd;
      ThreadStart ts = (ThreadStart)delegate
      {
           t.DoSomething();
      };
      thrd = new Thread(ts);
      thrd.Start();
 }

I have created a workaround but I am not satisfied with it. If anyone has a better suggestion please let me know. Here is the workaround:

void CallExceptionASync()
{
Thread thrd;
ThreadStart ts = (ThreadStart)delegate
{
try
{
t.DoSomething();
}
catch(MyCustomException ex)
{
this.lblMessage.Invoke((MethodInvokder)delegate()
{
this.lblMessage.Text = ex.Message;
});
}
}
}

if the thread throws an exception, and the catch is to touch a GUI Control, then you need Control.Invoke, there is no way around that since that thread is not allowed to touch any Controls. BTW: A BackgroundWorker has a Completed event which does the invoking automatically, and its event argument holds the exception that may have occurred. :)
