How do Timers work in .net?

I activated my windows timer and tried to stop but it seems not to be working, please see my code:

private void button1_Click(object sender, EventArgs e)
{
        timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
        MessageBox.Show("Hello");
        timer1.Stop();
}

It shows the message over and over again and it doesn't stop. Please give me some ideas, I am very grateful for your help.

You need to stop the timer before showing the message box. Otherwise they may pile up.

There is the System.Timers.Timer that can be configured to be a one-shot timer, but the general approach for other timers is:

When the timer event fires, stop the timer, do your thing and then start the timer again if needed.

At line MessageBox.Show("Hello"); The execution will stop there waiting for the user to press "OK" button, so line timer1.Stop(); won't be reached until user interacts with the message box, and the timer will continue to work this way.
