There are different kinds of threads, I think. The operating system's threads for the application you're running, can be counted with:

int number = Process.GetCurrentProcess().Threads.Count;

It seems to count System.Diagnostics.ProcessThread instances. Maybe you need to count another kind of thread, like "managed threads", so I'm not sure my answer is what you seek.
