Easily Cause StackOverflow Exception in ASP.NET Web Application

This is a short one, but since I can’t believe I’ve never managed to do this before, I thought I’d post a little tidbit on it. I threw a StackOverflow in one of my ASP.NET C# web applications today. Watching the request keep going for about 5 minutes, I checked the Event Log on the server. There it was, StackOverflow exception. Say, what?

How did I manage it? Recursively add a control to its own control collection. The .NET framework just freaks and the application pool just gets restarted after each exception kills the app. Glad it didn’t take long to figure it out!
