Getting the thread ID from a thread

In C# when debugging threads for example, you can see each thread's ID.

I couldn't find a way to get that same thread, programmatically. I could not even get the ID of the current thread (in the properties of the Thread.currentThread).

So, I wonder how does Visual Studio get the IDs of the threads, and is there a way to get the handle of the thread with id 2345, for example?

GetThreadId returns the ID of a given native thread. There are ways to make it work with managed threads, I'm sure, all you need to find is the thread handle and pass it to that function.

GetCurrentThreadId returns the ID of the current thread.

GetCurrentThreadId has been deprecated as of .NET 2.0: the recommended way is the Thread.CurrentThread.ManagedThreadId property.
