Generate white noise image in C#

White Noise is not black or white (per definition). It contains also grayscales.

So we are already closer with:

foreach(var pixel in image) 
{
  //do that for all RGB (depending on Image format)
  pixel = rand() * 255;
}

white noise

Should be something very simple along these lines, no?

foreach(var pixel in image)
{
    pixel = rand()>0.5 ? white : black;
}
