问题描述
我有一个 int 值为 60 的 lblCountdown.我想让 lblCountDown 的 int 值随秒减少,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.
这是我目前所拥有的:
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
为此使用 Timer
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();
}
