The AutoResetEvent class represents a local wait handle event that resets automatically when signaled, after releasing a single waiting thread. This class represents a special case of its base class, EventWaitHandle. See the EventWaitHandle conceptual documentation for the use and features of automatic reset events.
An AutoResetEvent object is automatically reset to non-signaled by the system after a single waiting thread has been released. If no threads are waiting, the event object's state remains signaled. AutoResetEvent corresponds to a Win32 CreateEvent call, specifying false for the bManualReset argument.
