virtual void Cancel(System::Activities::NativeActivityContext ^ context);protected virtual void Cancel (System.Activities.NativeActivityContext context);abstract member Cancel : System.Activities.NativeActivityContext -> unit
override this.Cancel : System.Activities.NativeActivityContext -> unitProtected Overridable Sub Cancel (context As NativeActivityContext)Parameters
- context
- NativeActivityContext
The execution context in which the activity executes.
Examples
The following code sample demonstrates using Cancel in a class that inherits from NativeActivity<TResult>. This example is from the Non-Generic ParallelForEach sample.
protected override void Cancel(NativeActivityContext context)
{
// If we don't have a completion condition then we can just
// use default logic.
if (this.CompletionCondition == null)
{
base.Cancel(context);
}
else
{
context.CancelChildren();
}
}
