Thread Safety

This type is safe for multithreaded operations.


This class is typically used as a base class for synchronization objects. Classes derived from WaitHandle define a signaling mechanism to indicate taking or releasing exclusive access to a shared resource, but use the inherited WaitHandle methods to block while waiting for access to shared resources.

Use the static methods of this class to block a thread until one or more synchronization objects receive a signal.
