Did you know: Find out if an exception was thrown from a finally block!

This is a big biggie for me, because it enables a much nicer syntax for a lot of stuff. But first, let us show this:

using(new ExceptionDetector())
	if(new Random().Next(1,10)%2 == 0)
          throw new Exception();

How can you tell, from the ExceptionDetector, if an exception was thrown or not? Well, conventional wisdom, and what I thought about until 15 minutes ago, says that you can't. I want to thank Daniel Fortunov, for teaching me this trick:

public class ExceptionDetector : IDisposable
    public void Dispose()
        if (Marshal.GetExceptionCode()==0)
            Console.WriteLine("Completed Successfully!");
