向 Windows 窗体应用程序添加计时器

问题描述

我想添加一个计时器而不是一个自动开始的倒计时表单加载.开始时间应为 45 分钟，一旦结束，即达到 0 分钟，表单应以显示消息结束.我该怎么做?

I want to add a timer rather than a countdown which automatically starts whenthe form loads. Starting time should be 45 minutes and once it ends, i.e. on reaching 0 minutes, the form should terminate with a message displayed. How can I do this?

语言:最好是C#.

更多细节:

    private void Form1_Load(object sender, EventArgs e)
    {
        Timer MyTimer = new Timer();
        MyTimer.Interval = (45 * 60 * 1000); // 45 mins
        MyTimer.Tick += new EventHandler(MyTimer_Tick);
        MyTimer.Start();
    }

    private void MyTimer_Tick(object sender, EventArgs e)
    {
        MessageBox.Show("The form will now be closed.", "Time Elapsed");
        this.Close();
    }
