Methods

Cancel()

Communicates a request for cancellation.

Declaration

public void Cancel()

Remarks

The associated cancelable will be notified of the cancellation and will transition to a state where IsCancellationRequested returns true. Any callbacks or cancelable operations registered with the cancelable will be executed. Cancelable operations and callbacks registered with the token should not throw exceptions. However, this overload of Cancel will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed. The ExecutionContext that was captured when each callback was registered will be reestablished when the callback is invoked.

Cancel(Boolean)

Communicates a request for cancellation, and specifies whether remaining callbacks and cancelable operations should be processed.

Declaration

public void Cancel(bool throwOnFirstException)

Parameters

Type	Name	Description
Boolean	throwOnFirstException	`true` if exceptions should immediately propagate; otherwise, `false`.

Remarks

The associated cancelable will be notified of the cancellation and will transition to a state where IsCancellationRequested returns true. Any callbacks or cancelable operations registered with the cancelable will be executed. Cancelable operations and callbacks registered with the token should not throw exceptions. If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed. The ExecutionContext that was captured when each callback was registered will be reestablished when the callback is invoked.

CancelAfter(Int32)

Schedules a cancel operation on this cancelable after the specified number of milliseconds.

Declaration

public void CancelAfter(int millisecondsDelay)

Parameters

Type	Name	Description
Int32	millisecondsDelay	The delay in milliseconds before this instance is canceled.

| Improve this Doc View Source

CancelAfter(TimeSpan)

Schedules a cancel operation on this cancelable after the specified delay.

Declaration

public void CancelAfter(TimeSpan delay)

Parameters

Type	Name	Description
TimeSpan	delay	The delay before this instance is canceled.
