Parameters

millisecondsTimeout

The number of milliseconds to wait for the lock.

obj

The object on which to acquire the lock.

millisecondsTimeout

The number of milliseconds to wait for the lock.

Returns

true if the current thread acquires the lock; otherwise, false.

Exceptions

Type	Reason
ArgumentNullException	obj is null.
ArgumentOutOfRangeException	millisecondsTimeout is negative, and not equal to Timeout.Infinite .

Remarks

If the millisecondsTimeout parameter equals Timeout.Infinite, this method is equivalent to Monitor.Enter(object). If millisecondsTimeout equals 0, this method is equivalent to Monitor.TryEnter(object).

Note:

Use System.Threading.Monitor to lock objects (that is, reference types), not value types. For details, see Monitor.Enter(object) and the conceptual topic [<topic://cpconMonitor>].
