Monitor.TryEnter Method (Object)
Attempts to acquire an exclusive lock on the specified object.
Assembly: mscorlib (in mscorlib.dll)
The obj parameter is a null reference (Nothing in Visual Basic).
If successful, this method acquires an exclusive lock on the obj parameter. This method returns immediately, whether or not the lock is available.
This method is similar to Enter, but it will never block. If the thread cannot enter without blocking, the method returns false, and the thread does not enter the critical section.
