注释
This event is called by the task to determine if the package wishes the task to cease executing. Because the package gives control to the task to execute and does not terminate tasks randomly, there needs to be a juncture at which the package may inform the task that it is attempting to shut down. If the value is true, the task should shut down and a cancelled message is returned from the Execute method of the task. If the value is false, the task continues to run as usual.
