NativeActivity<TResult>.Cancel Method

When implemented in a derived class, runs logic to cause graceful early completion of the activity.

Namespace:  System.Activities
Assembly:  System.Activities (in System.Activities.dll)

protected virtual void Cancel(
	NativeActivityContext context
)

Parameters

context
Type: System.Activities.NativeActivityContext
The execution context in which the activity executes.

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();
    }
}
