Methods

Enter(Object)	Acquires an exclusive lock on the specified object.
Enter(Object, Boolean)	Acquires an exclusive lock on the specified object, and atomically sets a value that indicates whether the lock was taken.
Exit(Object)	Releases an exclusive lock on the specified object.
IsEntered(Object)	Determines whether the current thread holds the lock on the specified object.
Pulse(Object)	Notifies a thread in the waiting queue of a change in the locked object's state.
PulseAll(Object)	Notifies all waiting threads of a change in the object's state.
TryEnter(Object)	Attempts to acquire an exclusive lock on the specified object.
TryEnter(Object, Boolean)	Attempts to acquire an exclusive lock on the specified object, and atomically sets a value that indicates whether the lock was taken.
TryEnter(Object, Int32)	Attempts, for the specified number of milliseconds, to acquire an exclusive lock on the specified object.
TryEnter(Object, Int32, Boolean)	Attempts, for the specified number of milliseconds, to acquire an exclusive lock on the specified object, and atomically sets a value that indicates whether the lock was taken.
TryEnter(Object, TimeSpan)	Attempts, for the specified amount of time, to acquire an exclusive lock on the specified object.
TryEnter(Object, TimeSpan, Boolean)	Attempts, for the specified amount of time, to acquire an exclusive lock on the specified object, and atomically sets a value that indicates whether the lock was taken.
Wait(Object)	Releases the lock on an object and blocks the current thread until it reacquires the lock.
Wait(Object, Int32)	Releases the lock on an object and blocks the current thread until it reacquires the lock. If the specified time-out interval elapses, the thread enters the ready queue.
Wait(Object, Int32, Boolean)	Releases the lock on an object and blocks the current thread until it reacquires the lock. If the specified time-out interval elapses, the thread enters the ready queue. This method also specifies whether the synchronization domain for the context (if in a synchronized context) is exited before the wait and reacquired afterward.
Wait(Object, TimeSpan)	Releases the lock on an object and blocks the current thread until it reacquires the lock. If the specified time-out interval elapses, the thread enters the ready queue.
Wait(Object, TimeSpan, Boolean)	Releases the lock on an object and blocks the current thread until it reacquires the lock. If the specified time-out interval elapses, the thread enters the ready queue. Optionally exits the synchronization domain for the synchronized context before the wait and reacquires the domain afterward.
