Question

我有一个计时器，在30分钟内我想计算点击次数并在文本框中显示。但怎么样？这是计时器代码：

decimal sure = 10;
private void button1_Click(object sender, EventArgs e)
{
  button1.Enabled = true;
  timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
  sure--;
  label3.Text = sure.ToString();
  if (sure == 0) 
  {
    timer1.Stop();
    MessageBox.Show("Süre doldu");
  }
}

Answer 1

在全局声明您的clickCounter，并在鼠标单击事件中提升您的计数器++。如果您更具体，可以使用后台工作程序来跟踪时间。并使用Application.DoEvents（）将剩余的内容写入textBox 放一个按钮，2个标签和一个计时器。使用lblClickCount和lblRemainingTime重命名标签

private int clickCounter = 0;
    private void button1_Click(object sender, EventArgs e)
    {
        clickCounter++;
        lblClickCount.Text = clickCounter.ToString();
    }

    decimal sure = 10;
    private void timer1_Tick(object sender, EventArgs e)
    {
        sure--;
        lblRemainingTime.Text = sure.ToString();
        Application.DoEvents();
        if (sure == 0)
        {
            timer1.Stop();
            MessageBox.Show("Süre doldu. Toplam tiklama sayisi:" + clickCounter.ToString());
        }
    }

如果您想重复使用buttoN1来计算点击次数而不是启动新计时器，则可以在要保护的代码周围添加if。

bool hasTimerStarted = false;
int numberOfClicks = 0;
private void button1_Click(object sender, EventArgs e)
{
  if(!hasTimerStarted)
  {
      button1.Enabled = true;
      timer1.Start();
      hasTimerStarted = true;
  }
  ++numberOfClicks;
}

当计时器到期时，您重置计数以及计时器是否已启动。

private void timer1_Tick(object sender, EventArgs e)
{

    TimeSpan ts = stopWatch.Elapsed;

    // Format and display the TimeSpan value.
    string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
        ts.Hours, ts.Minutes, ts.Seconds,
        ts.Milliseconds / 10);

    label3.Text = elapsedTime;
    labelClicks.Text = "User clicked " + clicksNo.toString() + "nt times..";

    if (stopWatch.ElapsedMilliseconds >= this.minutes * 60 * 1000) 
    {
        timer1.Stop();
        MessageBox.Show("Time elapsed.");
        hasTimerStarted = false;
        numberOfClicks = 0;
    }
}

c＃计算点击次数
