推荐答案

首先，将计时器设置为24小时间隔不是好主意 - 它没有给出任何真正的灵活性。我会将它设置为一个较小的间隔（例如一分钟）并使用计数器来判断一段时间已经过去，或者存储一段时间的值并检查它是否在过去。如果是这样的话，是时候做计时器所做的任何动作。



但是我不会从计时器那样做任务 - 我将使用 Windows任务计划程序 [ ^ ]在指定的时间运行我的应用程序......

First off, setting a timer to a 24 hour interval is not a brilliant idea - it doesn''t give any real flexibility. I would set it to a smaller interval (a minute for example) and use a counter to tell when a period has elapsed instead, or store a time-to-do-it value and check if that is in the past. If so, it''s time to do whatever action the timer is there for.

But I wouldn''t do a task like that from a Timer - I would use the Windows Task Scheduler[^] to run my app at the specified time instead...
