SemaphoreSlim::Wait Method (CancellationToken)

.NET Framework (current version)
 

Blocks the current thread until it can enter the SemaphoreSlim, while observing a CancellationToken.

Namespace:   System.Threading
Assembly:  mscorlib (in mscorlib.dll)

public:
void Wait(
	CancellationToken cancellationToken
)

Parameters

cancellationToken
Type: System.Threading::CancellationToken

The CancellationToken token to observe.

Exception Condition
OperationCanceledException

cancellationToken was canceled.

ObjectDisposedException

The current instance has already been disposed.

-or-

The CancellationTokenSource that created cancellationToken has already been disposed.

If a thread or task is able to enter the semaphore, it decrements the CurrentCount property by one.

If cancellationToken is cancelled, the thread or task doesn’t enter the semaphore, and the CurrentCount property isn’t decremented. Instead, the method throws an OperationCanceledException exception.
