C# How to detect an object is already locked

Question

How can I detect whether an object is locked or not?

Monitor.TryEnter (as described in Is there a way to detect if an object is locked?) does not work f

Answer 1

I can in no way advocate checking locks then entering code blocks. However, I found this thread while looking for a way to check a new function couldn't leave an object locked. A unit test based on Monitor.IsEntered got me exactly what I was looking for.
