Inter Thread Communication

C# supports interthread communication with the Wait( ), Pulse( ), and PulseAll( ) methods. The Wait( ), Pulse( ), and PulseAll( ) methods are defined by the Monitor class. These methods can be called only from within a locked block of code. When a thread is temporarily blocked from running, it calls Wait( ). The sleeping thread is awakened when some other thread calls Pulse( ) or PulseAll( ). A call to Pulse( ) resumes the first thread in the queue of threads waiting for the lock. A call to PulseAll( ) signals the release of the lock to all waiting threads.

Syntax:

public static bool Wait(object waitOb)

public static bool Wait(object waitOb, int milliseconds)

public static void Pulse(object waitOb)

public static void PulseAll(object waitOb)

Exception:
A SynchronizationLockException will be thrown if Wait( ), Pulse( ), or PulseAll( ) is called from code that is not within a lock block.
