我有一个秒表计时器,已添加到我的程序中。它在我的 Win 7 机器和我尝试过的 Vista 机器上运行良好,但在 XP 中,计时器启动时小时和分钟零会消失,但如果我重置计时器会回来。这是我所有的计时器代码。我已经删除了似乎不需要诊断问题的所有内容:
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));
}
