how to quickly create dummy image directly in .NET code

Question

How to quickly create some random image with the icon size? I don't want to use neither Image.FromFile, nor Image.FromStream

Answer 1

int width = 50;
int height = 50;
using (Bitmap bitmap = new Bitmap(width, height))
{

    // do something to the bitmap
    // perhaps use .SetPixel to maybe apply some color

    bitmap.Save("C:\\Temp\\random.bmp");
}
