秒表问题， [英] Problem in stopwatch,

问题描述

当我按下按钮时，我会调用计时器"表格:

When I press the button, I call the timer''form:

StopWatch.Show()
'StopWatch.Timer1.Start()

完成后，我将停止计时器:

When I''m finished, I''m stop the timer:

StopWatch.Timer1.Stop()
TextBox6.Text = StopWatch.TextBox1.Text
StopWatch.Close()

问题是，当我通过执行操作启动计时器时，计时器变得比我单独调用计时器表单时要慢.

是什么问题?

The problem is, when I start the timer with doing an operation, the timer become slower than when I call the timer form alone.

What is the problem?

推荐答案

尝试直接使用StopWatch类.
请参见此处 [

Try using the StopWatch class directly.
See here[^].

您所说的StopWatch不是实数" StopWatch，不是System.Diagnostics.Stopwatch.我不知道那是什么请参阅我对问题的评论.

为了获得最佳准确性，请使用 System.Diagnostics.Stopwatch.

恐怕您使用System.Windows.Timer.如果您需要任何合理的精度，请不要使用此类型(基本上，您根本不需要它)；这个计时器出了名的不正确！您观察到的可能是其优先级较低的结果.

而且，您几乎不需要使用计时器！在大多数情况下，线程更容易实现.结果将更加健壮；有关详细信息，请参阅我过去的答案:
C#中的计时器线程 [

What you call StopWatch is not a "real" StopWatch, not System.Diagnostics.Stopwatch. I don''t know what is it. See my comments to the question.

For best accuracy use System.Diagnostics.Stopwatch.

I''m afraid you use System.Windows.Timer. If you need any reasonable accuracy, don''t use this type (basically, you never need it at all); this timer is notoriously inaccurate! What you observe is maybe the effect of its low priority.

Moreover, you almost never need to use timers! In most cases, a thread is easier to implement; and the result will be much more robust; for details, please see my past answer:
