NativeActivity.Cancel(NativeActivityContext) Method

Definition

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

protected:
 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 -> unit
Protected 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();
    }
}
