How to resume a game timer from another form?

Question

I'm making a pong game in windows forms and I can't figure out how to unpause after pausing in my gameplay form. After pausing a pause screen form is started and after clicking unpause it unpauses, however, I don't know how to make the timer start again. Please let me know.

Here's my code: Gameplay form:

        if (isPaused)
            Paused();
    }

    private void Paused()
    {
        gameTimer.Stop();
        PausedScreen pausedWindow = new PausedScreen();
        pausedWindow.Show();
        isPaused = false;
    }

Pause Screen form:

    public PausedScreen()
    {
        InitializeComponent();
    }

    private void UnPause(object sender, EventArgs e)
    {
        Hide();
        //Resume timer
    }

    private void QuitGame(object sender, EventArgs e)
    {
        Application.Exit();
    }

You can catch the event "Closed" when your pausedScreen is closed and then restart the timer in this function.

gameTimer.Stop();
PausedScreen pausedWindow = new PausedScreen();
pausedWindow.Show();
isPaused = false;
pausedWindow.Closed += new EventHandler(Closed);

private void Closed(object sender, EventArgs e){
    gametimer.Start();
}

Hope this solves your problem.
