Sample Code:

    [DllImport("user32.dll")]
    static extern bool ClientToScreen(IntPtr hwnd, ref Point lpPoint);

    [DllImport("user32.dll")]
    static extern bool SetCursorPos(int X, int Y);

    public void UnmanagedMoveCursorOverButton(Button button)
    {
        IntPtr handle = IntPtr.Zero;
        Point point;
        int x = 0;
        int y = 0;
        int width = 0;
        int height = 0;
        bool coordinatesFound = false;

        if (button != null)
        {
        width = button.Size.Width;
        height = button.Size.Height;
        handle = button.Handle;
        }

        if ((width > 0) && (height > 0))
        {
        point = new Point();
        x = (width / 2);
        y = (height / 2);

        coordinatesFound = ClientToScreen(handle, ref point);

        if (coordinatesFound == true)
        {
            SetCursorPos(point.X + x, point.Y + y);
        }
        }
    }

    public void ManagedMoveCursorOverButton(Button button)
    {
        IntPtr handle = IntPtr.Zero;
        Point point;
        int x = 0;
        int y = 0;
        int width = 0;
        int height = 0;
        bool coordinatesFound = false;

        if (button != null)
        {
        width = button.Size.Width;
        height = button.Size.Height;
        handle = button.Handle;
        }

        if ((width > 0) && (height > 0))
        {
        point = new Point();
        x = (width / 2);
        y = (height / 2);

        coordinatesFound = ClientToScreen(handle, ref point);

        if (coordinatesFound == true)
        {
          point.X += x;
          point.Y += y;
          System.Windows.Forms.Cursor.Position = point;
        }
