How to check if the WaitHandle was set?

I have a WaitHandle and I would like to know how to check if the WaitHandle has already been set or not.

Note: I can add a bool variable and whenever Set() method is used set the variable to true, but this behaviour must be built in WaitHandle somewhere.

Thanks for help!

Try WaitHandle.WaitOne(0)

If millisecondsTimeout is zero, the method does not block. It tests the state of the wait handle and returns immediately.
