title: How can I create one System.Drawing.Icon from multiple Bitmaps?
body: <p>How can I create an Icon object that contains multiple sizes? I cannot load it from a resource because the content is created from different overlayed bitmaps. I cannot create a .ico file because the bitmaps are generated at runtime.</p>
  
  <p>I have 4 Bitmap objects (16x16, 32x32, 64x64 and 128x128). I want to combine these 4 Bitmaps into a single Icon object.</p>
