How to draw a zigzag line?

Question

I am creating a document based application and i want to draw a horizontal line underlying the text. But, line should not be straight. i want to draw a line like this.

Currently i am using System.Graphics object to draw any object.

private void DrawLine(Graphics g, Point Location, int iWidth)
{
    iWidth = Convert.ToInt16(iWidth / 2);
    iWidth = iWidth * 2;
    Point[] pArray = new Point[Convert.ToInt16(iWidth / 2)];
    int iNag = 2;
    for (int i = 0; i < iWidth; i+=2)
    {
        pArray[(i / 2)] = new Point(Location.X + i , Location.Y + iNag);
        if (iNag == 0)
            iNag = 2;
        else
            iNag = 0;
    }
    g.DrawLines(Pens.Black, pArray);
}

UPDATED:
Above code is working fine and line draws perfectly but, this code effects on application performance. Is there another way to do this thing.

If you want fast drawing just make a png image of the line you want, with width larger than you need and then draw the image:

private void DrawLine(Graphics g, Point Location, int iWidth)
{
    Rectangle srcRect = new Rectangle(0, 0, iWidth, zigzagLine.Height);
    Rectangle dstRect = new Rectangle(Location.X, Location.Y, iWidth, zigzagLine.Height);

    g.DrawImage(zigzagLine, dstRect, srcRect, GraphicsUnit.Pixel);
}

zigzagLine is the bitmap.
