我有一个int值为60的lblCountdown.我想让lblCountDown的int值减少几秒,直到达到0.

这是我到目前为止:

   private int counter = 60;
    private void button1_Click(object sender, EventArgs e)
    {
        int counter = 60;
        timer1 = new Timer();
        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Interval = 1000; // 1 second
        timer1.Start();
        label1.Text = counter.ToString();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        counter--;
        if (counter == 0)

            timer1.Stop();
            label1.Text = counter.ToString();

    }

private void btnStart_Click(object sender, EventArgs e)
{
    Random random = new Random();
    int randomNumber = random.Next(0, 1000);
    int RandomTolerance = 5 || 10;
    lblRandomValue.Text = randomNumber + "000" + "O" + RandomTolerance;
}

我不明白如何只允许RandomTolerance在5到10之间选择一个整数.
