我有一个计时器，当标签中的文字出现时，如何启动，当您点击按钮时停止。现在我想停止reaktiontime并将其保存在列表中，我想对其进行排序，这样我就可以在标签中给出最快和最低的reaktiontime。但在我的代码中，每次它在消息框中显示00:00:00 :(
public partial class Form1 : Form
{
Random r = new Random();
Random Farbe = new Random();
bool Start_MouseClick;
IList<string> Reaktionszeitliste = new List<string>() {};
IList<Color> myColors = new[] { Color.Red, Color.Blue, Color.Green, Color.White, Color.Yellow };
string[] colors = { "Rot", "Blau", "Grün", "Gelb", "Weiß" };
int Timeleft = 5;
int summe = 0, z;
string Reaktionszeit;
int Zeit;
int Spielzuege = 0;
DateTime Time1;
DateTime Time2;
TimeSpan ts;
private void btnRot_Click(object sender, EventArgs e)
{
Spielzuege = Spielzuege + 1;
timMessung.Stop();
if (Start_MouseClick == true)
{
int summe = 0, z;
lblAnzeige.Text = " ";
while (summe <= 0)
{
z = r.Next(1, 6);
summe = summe + z;
}
lblAnzeige.Text += colors[summe - 1] + "\n";
Zeit = 0;
timMessung.Enabled = true;
if (ckbExtrem.Checked == false)
{
lblAnzeige.ForeColor = myColors[Farbe.Next(myColors.Count)];
}
else
{
lblAnzeige.ForeColor = Color.FromArgb(Farbe.Next(256), Farbe.Next(256), Farbe.Next(256));
}
if (Spielzuege == 15)
{
if (txbPlayer2.Text != "")
{
MessageBox.Show("Spieler 2: Machen Sie sich bereit!");
}

我认为您的问题是DateTime的分辨率小于您尝试测量的间隔。
请尝试以下方法，而不是使用DateTime：
创建一个名为Stopwatch的私人stopwatch字段。
Stopwatch stopwatch = new Stopwatch();
然后将您的tick处理程序更改为：
private void timMessung_Tick(object sender, EventArgs e)
{
if (timMessung.Enabled == true)
{
stopwatch.Restart();
}
else
{
ts.stopwatch.Elapsed();
}
}
但是，当你重新启动秒表时，我也不确定你的逻辑。 （我把stopwatch.Restart()放在哪里。）你真的想继续重新启动秒表吗？

在第一次运行中，我试图改变你的代码，以便它运行。但我在那里发现了很多（编码风格）问题，我只是写了一个全新的例子。它也有一些小问题（例如按钮的大小;颜色按钮可能出现两次）。但它希望向您展示TimeSpan以及所有其他部分如何协同工作。
