[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Communicates a request for cancellation.

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

'Declaration
Public Sub Cancel

ExceptionCondition
ObjectDisposedException

This CancellationTokenSource has been disposed.

AggregateException

An aggregate exception containing all the exceptions thrown by the registered callbacks on the associated CancellationToken.

The associated CancellationToken will be notified of the cancellation and will transition to a state where IsCancellationRequested returns true.

Any callbacks or cancelable operations registered with the CancellationToken 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.
