Question

我在这里遇到一些代码问题，就像你有一个最大化和控制屏幕的表格，当你登录时你有时间使用电脑，在时间停止或结束时计算表格的时间将会结束再次最大化。

问题是，如果计时器停止或计数

，我不知道如何捕捉

谢谢你的时间！

您可以使用Timer组件并在表单中设置结束时间，并在Tick事件检查中DateTime.Now是否大于或等于结束时间，然后是给定的时间结束了。

在下面的示例中，我假设您有一个PasswordForm，当密码正确时会返回DialogResult.OK。我会在开始时显示密码表单，并在时间结束时显示：

DateTime endTime;

private void MainForm_Load(object sender, EventArgs e)
{
    ShowPasswordForm();
}

private void ShowPasswordForm()
{
    timer1.Stop();
    var f = new PasswordForm();
    var passed = false;
    while (!passed)
    {
        if (f.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            passed = true;
    }
    var startTime = DateTime.Now;
    endTime = startTime.AddMinutes(1); //I used 1 minute for test, add the time you need.
    timer1.Interval = 1000;
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    var diff = endTime.Subtract(DateTime.Now);
    this.Text = string.Format("Remaining: {0} d {1:D2}:{2:D2}:{3:D2}",
                            diff.Days, diff.Hours, diff.Minutes, diff.Seconds);

    if (DateTime.Now >= endTime)
    {
        timer1.Stop();
        this.Text = "Remaining: 0 d 00:00:00";
        MessageBox.Show("Time is over.");
        ShowPasswordForm();
    }
}

如果您在表单中需要它，可以使用工具栏中的控件，如下所示：

class Timer : Form {
    var myTimer = new System.Windows.Forms.Timer();

    private void TimerEventProcessor(Object myObject, EventArgs myEventArgs) {
        // If you want handle interval once call Stop method, if not remove this line
        myTimer.Stop();

        // Call waht you want
    }

    public void Run() {
        myTimer.Tick += TimerEventProcessor;

        // Sets the timer interval to 5 seconds.
        myTimer.Interval = 5000;
        myTimer.Start();
    }
}

完成计数时间后重新打开表格
