        public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
        private const int MOUSEEVENTF_LEFTDOWN = 0x02;
        private const int MOUSEEVENTF_LEFTUP = 0x04;

        public void DoMouseClick()
        {
            uint X = (uint)Screen.PrimaryScreen.WorkingArea.Width / 2;
            uint Y = (uint)Screen.PrimaryScreen.WorkingArea.Height / 2;
            mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
        }

In order to change the position of where the click shoud happen, you need to change the following lines

            uint X = (uint)Screen.PrimaryScreen.WorkingArea.Width / 2;
            uint Y = (uint)Screen.PrimaryScreen.WorkingArea.Height / 2;
