How do I move two graphic paddles(pong) at the same time using one keyboard in C#?

[endorfinState]

        protected override void OnKeyDown(KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Up) 
                paddleY = paddleY - 15;
            else if (e.KeyCode == Keys.Down)
                paddleY = paddleY + 15;
            else if (e.KeyCode == Keys.W) 
                paddleY2 = paddleY2 - 15;
            else if (e.KeyCode == Keys.S)
                paddleY2 = paddleY2 + 15;
 
            Invalidate();
            base.OnKeyDown(e);
        }

Make Keys.Up, Keys.Down AND Keys.W, Keys.S their own if statements. Right now this is just one big if statement, and only one condition can be ran at a time, so how do you expect more than one paddle to move here?

It should be... if Keys.Up {} else if Keys.Down {}, and then if Keys.W {} else if Keys.S {}.
