Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type CancellationTokenSource.

ExceptionCondition
ArgumentNullExceptionIf cts is .
ObjectDisposedExceptionIf cts has been disposed.
ArgumentOutOfRangeExceptionIf the TotalMilliseconds property of delay is less than -1 or greater than MaxValue.
Remarks
If a previous call to this method scheduled a cancellation, the cancellation time is reset to the new delay value. This method has no effect if the CancellationTokenSource has already been cancelled (i.e. the IsCancellationRequested property returns .

In all versions of .NET, requesting cancellation of a CancellationTokenSource will not prevent the instance from becoming eligible for garbage collection prior to the timer expiring. In .NET 4 and newer, any associated Timer instance will become eligible for garbage collection at the same time as the associated CancellationTokenSource.
