秒倒数计时器

问题描述

我有一个lblCountdown，其int值为60。我想使lblCountDown的int值随着秒减小直到达到0。

I have a lblCountdown with an int value of 60. I want to make the int value of the lblCountDown decrease with seconds until it reaches 0.

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();

    }

推荐答案

使用计时器为此

   private System.Windows.Forms.Timer timer1;
   private int counter = 60;
   private void btnStart_Click_1(object sender, EventArgs e)
   {
        timer1 = new System.Windows.Forms.Timer();
        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Interval = 1000; // 1 second
        timer1.Start();
        lblCountDown.Text = counter.ToString();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        counter--;
        if (counter == 0)
            timer1.Stop();
        lblCountDown.Text = counter.ToString();
    }
