Create an Icon from an Image

The following C# code changes an image object into an icon.

public static Icon ConvertImageToIcon(Image img)
{
  if (img == null)
    return null;
  Bitmap square = new Bitmap(img.Width, img.Height); // create new bitmap
  Graphics g = Graphics.FromImage(square);           // allow drawing to it
  g.DrawImage(img, 0, 0, img.Width, img.Height);     // draw image with specified dimensions
  g.Flush();                                         // make sure all drawing operations complete before we get the icon
  return Icon.FromHandle(square.GetHicon());
}
