SpinLock.TryEnter Method (Boolean)
Attempts to acquire the lock in a reliable manner, such that even if an exception occurs within the method call, lockTaken can be examined reliably to determine whether the lock was acquired.
Assembly: mscorlib (in mscorlib.dll)
Unlike Enter, TryEnter will not block waiting for the lock to be available. If the lock is not available when TryEnter is called, it will return immediately without any further spinning.
