| Exception | Condition |
|---|---|
| OperationCanceledException | cancellationToken has been canceled. |
| ObjectDisposedException | The current instance has already been disposed. |
| ArgumentOutOfRangeException | millisecondsTimeout is a negative number other than -1, which represents an infinite time-out. |
| InvalidOperationException | The method was invoked from within a post-phase action, the barrier currently has 0 participants, or the barrier is signaled by more threads than are registered as participants. |
If the cancellationToken was canceled before the signal took effect, then an OperationCanceledException is thrown and the ParticipantsRemaining value is not decreased. If the cancellationToken is not canceled or is canceled after the signal takes effect then ParticipantsRemaining is decreased and no OperationCanceledException is thrown.
