A reader asks:
I’m using locks in my application to synchronize work on a bunch of threads. Unfortunately, I’m doing something incorrectly and my threads seem to just stop sometimes. I think I’m running into deadlocks, but I’m not sure how to find them. Is there any way I can do so programmatically? I’d like an exception to be thrown when a deadlock is encountered.
In the October issue of MSDN Magazine, Stephen Toub answers this question by explaining how deadlocks occur, then building a sample DdMonitor class that wraps the .NET System.Threading.Monitor class and includes deadlock detection capabilities.
Don’t forget to browse the code online to explore the DdMonitor class further.
