How to use Keyboard events to stop a Timer in Windows Forms?

Question

I want to stop a timer which is running in my Windows Form by pressing any key from the keyboard. Do you have any idea ?

For example, inside my Form, I am trying this :

myTimer.Tick += new EventHandler(TimerEventProcessor);
myTimer.Interval = 400;
if (Keyboard.IsKeyDown(Key.Enter))
{
    if (myTimer.Enabled)
         myTimer.Stop();
}

The problem is even I have already added the assembly PresentationCore.dll but Keyboard in the code above is not recognized. And I'am facing this error:

!!! "the name keyboard does not exist in the current context"

You also need to add the reference WindowsBase.dll.

And check it in timer handler.

int i = 0;
private void timer1_Tick(object sender, EventArgs e)
{
    Console.WriteLine(i++);

    if (System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.Enter))
    {
        timer1.Enabled = false;
        MessageBox.Show("Timer Stopped");
    }
}

private void Form1_Load(object sender, EventArgs e)
{
    timer1.Enabled = true;
}
