Question

我正在尝试制作一个程序，其中有两个定时器以不同的间隔运行。目前我有1个计时器工作正常，我需要另一个运行。我的第一个计时器的代码如下所示：

    private void startButton_Click(object sender, RoutedEventArgs e)
    {
        Random rand = new Random();
        int ranMin = rand.Next(1,24);
        int ranSec = rand.Next(0, 59);


        System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
        dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
        dispatcherTimer.Interval = new TimeSpan(0, ranMin, ranSec);
        dispatcherTimer.Start();

        min.Content = ranMin;
        sec.Content = ranSec;

        openP();

    }

    private void dispatcherTimer_Tick(object sender, EventArgs e)
    {
        **code for timer in here
    }

这很好用，但现在我需要另一个以1秒间隔运行不同代码的计时器，当我尝试通过将所有dispatcherTimer放入dispatcherTimer2来复制它时，我遇到了错误。

我不确定你在做什么（你应该发布错误），但以下内容适用于您提供的代码：

    private void startButton_Click(object sender, RoutedEventArgs e)
        {
            Random rand = new Random();
            int ranMin = rand.Next(1,24);
            int ranSec = rand.Next(0, 59);


            System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
            dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
            dispatcherTimer.Interval = new TimeSpan(0, ranMin, ranSec);
            dispatcherTimer.Start();

            // New timer
            System.Windows.Threading.DispatcherTimer dispatcherTimer2 = new System.Windows.Threading.DispatcherTimer();
            dispatcherTimer2.Tick += new EventHandler(dispatcherTimer2_Tick);
            dispatcherTimer2.Interval = new TimeSpan(0, 0, 1);
            dispatcherTimer2.Start();

            min.Content = ranMin;
            sec.Content = ranSec;

            openP();

        }

        private void dispatcherTimer_Tick(object sender, EventArgs e)
        {
            //code for timer in here
        }

        private void dispatcherTimer2_Tick(object sender, EventArgs e)
        {
           //code for timer2 in here
        }

同一程序中的多个计时器
