How to make a 00:00 timer in c#?

I'm just trying to make a basic mm:ss timer for a little sports scoreboard.

I currently have 

int i = 0;
private void matchTimer_Tick(object sender, EventArgs e)
{
    i++;
    timeDisplay.Text = i.ToString("00:00");
}

But this fails because it doesn't account for minutes, so once time gets to 60, it just carries on

00:60
00:61
00:62
...

But I want it to be

01:00
01:01
01:02
...

and then stop at 80 minutes

You have more problems than you think. You're currently relying on the timer ticking exactly once per second. Don't do that - instead, use a System.Diagnostics.Stopwatch to measure the elapsed time, and then update the display by formatting the value of Stopwatch.Elapsed:

timeDisplay.Text = stopwatch.Elapsed.ToString("mm':'ss");

(See the Custom TimeSpan format strings documentation for more details.)
