CancellationTokenSource Constructor (TimeSpan)

Initializes a new instance of the CancellationTokenSource class that will be canceled after the specified time span.

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

Public Sub New ( _
	delay As TimeSpan _


Type: System.TimeSpan

The time span to wait before canceling this CancellationTokenSource.


delay.TotalMilliseconds is less than -1 or greater than Int32.MaxValue.

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

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