c# draw - Add random lines in a image

I have an image which I just want to add some random lines in. I am not so familiar with c# draw features.

Is there any simple way to add somewhere between 4-7 different length lines different places in an already bitmap object ?

Try something like this:

Random rnd = new Random();
Graphics g = Graphics.FromImage(bitmap);
for (int i=0; i<n; i++) {
    // calculate line start and end point here using the Random class:
    int x0 = rnd.Next(0, bitmap.Width);
    int y0 = rnd.Next(0, bitmap.Height);
    int x1 = rnd.Next(0, bitmap.Width);
    int y1 = rnd.Next(0, bitmap.Height);
    g.DrawLine(Pens.White, x0, y0, x1, x1);
}
