Describe the environment in which a wait () call is legal?

Solution

Object.wait() call must be placed in synchronized block, otherwise an IllegalMonitorStateException is thrown.

You can call the wait method like the following:-

The Wait() method does the following, in order:

This means that despite appearances, no lock is held on the synchronization object while Monitor.Wait awaits a pulse:

lock (object){

while (!_go)

    Monitor.Wait (object); // _lock is released

// lock is regained

}

Execution then continues at the next statement. Monitor.Wait is designed for use within a lock statement; it throws an exception if called otherwise.
