这个片段可以缩短，所以它仍然显示当前时间
像这样：08:24:09？
而不是这样 8:24.9

我目前的代码：

this.lblClock = new System.Windows.Forms.Label();
this.lblClock.Text = "00:00:00";

时钟滴答声：

    private void _Clock_Tick(object sender, EventArgs e)
    {
        DateTime CurrTime = DateTime.Now;

        if (CurrTime.Hour > 9 && CurrTime.Minute > 9 && CurrTime.Second > 9)
            lblClock.Text = ("" + CurrTime.Hour + ":" + CurrTime.Minute + ":" + CurrTime.Second);
        if (CurrTime.Hour < 10 && CurrTime.Minute > 9 && CurrTime.Second > 9)
            lblClock.Text = ("0" + CurrTime.Hour + ":" + CurrTime.Minute + ":" + CurrTime.Second);
        if (CurrTime.Hour > 9 && CurrTime.Minute > 9 && CurrTime.Second < 10)
            lblClock.Text = ("" + CurrTime.Hour + ":" + CurrTime.Minute + ":" + "0" + CurrTime.Second);
        if (CurrTime.Hour < 10 && CurrTime.Minute > 9 && CurrTime.Second < 10)
            lblClock.Text = ("0" + CurrTime.Hour + ":" + CurrTime.Minute + ":" + "0" + CurrTime.Second);
        if (CurrTime.Hour > 9 && CurrTime.Minute < 10 && CurrTime.Second > 9)
            lblClock.Text = ("" + CurrTime.Hour + ":" + "0" + CurrTime.Minute + ":" + CurrTime.Second);
        if (CurrTime.Hour < 10 && CurrTime.Minute < 10 && CurrTime.Second > 9)
            lblClock.Text = ("0" + CurrTime.Hour + ":" + "0" + CurrTime.Minute + ":" + CurrTime.Second);
        if (CurrTime.Hour > 9 && CurrTime.Minute < 10 && CurrTime.Second < 10)
            lblClock.Text = ("" + CurrTime.Hour + ":" + "0" + CurrTime.Minute + ":" + "0" + CurrTime.Second);
        if (CurrTime.Hour < 10 && CurrTime.Minute < 10 && CurrTime.Second < 10)
            lblClock.Text = ("0" + CurrTime.Hour + ":" + "0" + CurrTime.Minute + ":" + "0" + CurrTime.Second);
    }

你能缩短那个片段吗？

您可以使用 DateTime 格式"HH:mm:ss"在标签中显示时间。

lblClock.Text = CurrTime.ToString("HH:mm:ss");

如果你想显示上午/下午，那么你可以这样做：

lblClock.Text = CurrTime.ToString("hh:mm:ss tt");

查看DateTime.ToString(...)上的 MSDN 页面

你可以做各种格式！...包括"HH:mm:ss"，这就是你所追求的。
