我有一个秒表计时器,我已添加到我的程序中。它在我的Win 7机器上运行良好,在我试过的Vista机器上工作正常,但在XP中,当定时器启动时,小时和分钟零消失,但如果我重置定时器,它将返回。这是我为计时器提供的所有代码。我删除了诊断问题似乎没有必要的所有内容:

  DateTime startTime, stopTime;
    TimeSpan stoppedTime;
    bool reset;



    private void btnStopwatchStart_Click(object sender, EventArgs e)
    {
        // Start timer and get starting time
        if (reset)
        {
            reset = false;
            startTime = DateTime.Now;
            stoppedTime = new TimeSpan(0);
        }
        else
        {
            stoppedTime += DateTime.Now - stopTime;
        }
        stopwatchTimer.Enabled = true;
    }

    private void btnStopwatchReset_Click(object sender, EventArgs e)
    {
        // Reset displays to zero
        reset = true;
        lblElapsed.Text = "00:00:00";
    }

    private void btnStopwatchPause_Click(object sender, EventArgs e)
    {
        // Stop timer
        stopTime = DateTime.Now;
        stopwatchTimer.Enabled = false;
    }

    private void stopwatchTimer_Tick(object sender, EventArgs e)
    {
        DateTime currentTime;
        // Determine elapsed and total times
        currentTime = DateTime.Now;

        // Display times
        lblElapsed.Text = HMS(currentTime - startTime - stoppedTime);
    }

    private string HMS(TimeSpan tms)
    {
        // Format time as string, leaving off last six decimal places
        string s = tms.ToString();
        return (s.Substring(0, s.Length - 6));
    }

答案 0 :(得分:2)

可能是旧版本的.NET?您的HMS()函数关键取决于TimeSpan.ToString()生成的位数。这是一种更好的格式化方法:

    private static string HMS(TimeSpan tms) {
        return new DateTime(tms.Ticks).ToString("H:mm:ss");
    }
