如何在C＃中只提高1个Timer事件？ [英] How to raise only 1 Timer event in C#?

问题描述

如何一次定时启动一个定时器事件。
例如，我有一个定时器，每10分钟会引发一个事件。
引发的事件需要10分钟或更长时间才能完成执行。
我希望计时器在事件结束后复位。
换句话说，我不想在任何一个时间提出超过一个事件的实例。

How do I get a timer event to fire one at a time. For example I have a timer that raises an event every 10 minutes. The event that is raised takes 10 or more minutes to finish executing. I would like the timer to reset AFTER the event has finished. In other words I do not want to raise more than 1 instance of the event at any one time.

推荐答案

通常我做的是让事件停止计时器的提醒，然后在事件进程完成时重新启动计时器：

Usually what I do is have my event stop the timer when it's raised and then restart the timer when the event process completes:

private void timerHandler(object sender, TimerElapsedEventArgs e)
{
    Timer timer = (Timer)sender;
    timer.Stop();
    RunProcess();
    timer.Start();
}

public void RunProcess()
{
    /* Do stuff that takes longer than my timer interval */
}

现在我的计时器将在流程完成后再次启动

Now my timer will start again on completion of the process
