在一个Label上显示秒数
private void timer1_Tick(object sender, EventArgs e)
{
int number ;
number = int.Parse(lblsecond.Text);
number++;
lblsecond.Text = number.ToString();
}
private void timer1_Tick(object sender, EventArgs e)
{
int number ;
number = int.Parse(lblsecond.Text);
number++;
lblsecond.Text = number.ToString();
}
int number=0 ;
int.TryParse(lblsecond.Text,out number);
number++;
lblsecond.Text = number.ToString();
private void timer1_Tick(object sender, EventArgs e)
{
int number ;
number = int.Parse(lblsecond.Text);
number++;
lblsecond.Text = number+"";
}
private void timer1_Tick(object sender, EventArgs e)
{
int number ;
number = int.Parse(lblsecond.Text);
number++;
if(number > 59)
{
number = 0;
}
lblsecond.Text = number.ToString();
}
number 没用初始化;
int number = 0 ;
在别的地方比如一个按钮点击事件里加入timer1.start();
