C#动态显示系统时间

private void timer1_Tick(object sender, EventArgs e)
        {
            DateTime dt = DateTime.Now;
            label1.Text = dt.ToString();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            timer1.Enabled = true;
        }

Timer,Interval设为1000，反正显示也是1秒一秒来的
