Public ReadOnly Property WaitHandle As WaitHandle

Property Value

Type: System.Threading.WaitHandle

A WaitHandle that is signaled when the token is canceled.

Exception Condition

The associated CancellationTokenSource has been disposed.

Accessing this property causes a WaitHandle to be instantiated. It is preferable to only use this property when necessary, and to then dispose the associated CancellationTokenSource instance at the earliest opportunity (disposing the source will dispose of this allocated handle). The handle should not be closed or disposed directly.
