The Image class actually has a GetThumbnailImage method. Example usage:

var filename = "fb.png";

using(var image = Image.FromFile(filename))
{
    using(var thumbnail = image.GetThumbnailImage(20/*width*/, 40/*height*/, null, IntPtr.Zero))
    {
        thumbnail.Save("thumb.png");
    }
}

This will generate a 20x40px thumbnail version of fb.png and save it to thumb.png.
