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

Monitor.IsEntered should do the trick.

Edit: I just re-read the documentation, and it says:

Determines whether the current thread holds the lock on the specified object.

So that is not sufficient, as you would probably like to know if a different thread holds a lock?
