如何取消已执行的任务 [英] How to Cancel an already executed task

问题描述

我的问题是如何取消已执行的任务。假设我有10个任务，我已将这些任务放在基于异步方法的计时器中。由于它是基于计时器的应用程序，因此这些任务将一次又一次地执行。但是，我不希望这种情况发生。如果任务1已经完成，则不应再次执行。



任何人都可以通过一个例子来帮助我。

Hi,

My question is How do you cancel an already executed task. Lets say I have 10 tasks and I have put these tasks in a timer based async method. Since it is a timer based application, these tasks will be executed again and again. But, I don't want this to happen. If Task 1 is already finished then it should not be executed again.

Can anyone help me out in this regard with an example.
