秒表显示经过时间的计数器? [英] StopWatch to Show Counter of Elapsed Time?

问题描述

我的 Windows 窗体上有一个文本框，我想显示我的程序所花费的时间，但我没有在文本框中看到任何时间计数.下面是我的代码

I have a textbox on my windows form that I am wanting to show the elapsed time that my procedure has taken, but I am not seeing any time counting in the textbox. Below is my code

public partial class Form1 : System.Windows.Forms.Form
{
  private Stopwatch watch = new Stopwatch()l

  private void btn_RashadSL()
  {
    watch.Start();
    //lots of code here that typically takes around 15 - 20 minutes to complete
  }
  private void timer_Tick(object sender, EventArgs e)
  {
    textbox1.Text = watch.Elapsed.Seconds.ToString();
  }
}

推荐答案

鉴于您发布的代码，我认为问题在于您从未设置过计时器来实际调用 timer_Tick方法.

Given the code you have posted I'd say the problem is that at no point have you set up a timer to actually call the timer_Tick method.
