C# 时间跨度是如何工作的？

我有一个计时器，当标签中的文本出现时如何开始，当你点击按钮时停止。现在我想停止reaktiontime并将其保存在一个列表中，我想对其进行排序，以便在标签中给出最快和最短的reaktiontime。但在我的代码中，每次在messagebox中显示00:00:00时：（

公共部分类表单1:表单

随机r=新随机（）；
随机Farbe=新随机（）；
bool Start_鼠标单击；
IList ReaktionsZeitList=新列表（）{}；

如果（开始\鼠标单击==真）

int summe=0，z；
lblAnzeige.Text=“”；
而（summe我认为您的问题在于
DateTime
的分辨率小于您试图测量的间隔

请尝试以下操作，而不是使用
DateTime
：

创建名为
Stopwatch
的私有
Stopwatch
字段

Stopwatch stopwatch = new Stopwatch();

然后将记号处理程序更改为：

private void timMessung_Tick(object sender, EventArgs e)
{
    if (timMessung.Enabled == true)
    {
        stopwatch.Restart();
    }
    else
    {
        ts.stopwatch.Elapsed();
    }
}

但是，我也不确定重新启动秒表时的逻辑。（我将
stopwatch.restart（）
）您真的要在此时继续重新启动秒表吗？
使用：

ts = Time1.subtract(Time2);

如何计算日期时间差异：

在第一次运行时，我试图修改您的代码，使其能够运行。但我发现其中存在太多（编码风格）问题，因此我只编写了一个全新的示例。它还有一些小问题（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
和所有其他部分如何协同工作
