c# - Add timer to a Windows Forms application

Question

I want to add a timer rather than a countdown which automatically starts when the 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?

Language: preferably C#.

Bit more detail:

    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();
    }
