CancellationTokenSource Constructor (Int32)

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

Constructs a CancellationTokenSource that will be canceled after a specified time span.

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

public CancellationTokenSource(
	int millisecondsDelay


Type: System.Int32
The time span to wait before canceling this CancellationTokenSource.


The exception that is thrown when millisecondsDelay is less than -1.

The countdown for the millisecondsDelay starts during the call to the constructor. When the millisecondsDelay expires, the constructed CancellationTokenSource is canceled (if it has not been canceled already).

Subsequent calls to CancelAfter will reset the millisecondsDelay for the constructed CancellationTokenSource, if it has not been canceled already.
