Можно ли расположить линии на picturebox используя массив?

        private void PictureBox1_Paint(object sender, PaintEventArgs e)
        {
            int n = 5;
            for(int i = 0; i < n; i++)
                e.Graphics.DrawLine(Pens.Black, 0, i * pictureBox1.Height / n, 
                pictureBox1.Width, i * pictureBox1.Height / n + pictureBox1.Height / n);
        }

        bool draw = false;
        private void button_Click(object sender, EventArgs e)
        {
                draw = !draw;
                pictureBox1.Invalidate();
        }
 
        private void PictureBox1_Paint(object sender, PaintEventArgs e)
        {
            if(!draw) return;
            int n = 5;
            for(int i = 0; i < n; i++)
                e.Graphics.DrawLine(Pens.Black, 0, i * pictureBox1.Height / n, 
                pictureBox1.Width, i * pictureBox1.Height / n + pictureBox1.Height / n);
        }

private void Form1_Load(object sender, EventArgs e) 
{ 
pictureBox1.Image = new Bitmap(pictureBox1.Width, pictureBox1.Height); 
Graphics g = Graphics.FromImage(pictureBox1.Image); 
int cnt = 0; 
Point[] points = new Point[2]; 
while(cnt++ < 5) 
{ 
points[0].X = cnt < 4 ? 0 : pictureBox1.Width * (cnt - 3) / 8; 
points[0].Y = cnt < 4 ? pictureBox1.Height * cnt / 3 : pictureBox1.Height; 
points[1].X = cnt > 8 ? pictureBox1.Width : pictureBox1.Width * cnt / 8; 
points[1].Y = cnt > 8 ? pictureBox1.Height * (cnt - 8) / 3 : 0; 
g.DrawLine(Pens.Black, points[0], points[1]); 
} 
}
