How to copy an animated gif image using C#?

Is there a method to create a copy of an animated gif image using C#?
What I want is to generated a copy of a given gif image using the height and width parameters that the user provides. I have tried for a couple of hours to accomplish this but the resulting image does not preserve the original animations.
Thanks in advance.

From stackoverflow

• You need to loop through the frames in the animated GIF and resize each one.

  May also want to take a look at GifLib.
