注解
如果已取消的任务具有关联的取消标记, 则CancellationToken属性将返回该任务, 并且该标记的CancellationToken.IsCancellationRequested属性将设置为true。If the task that was canceled had an associated cancellation token, it is returned by the CancellationToken property, and the CancellationToken.IsCancellationRequested property of the token is set to true.
