Вывод анимированных Gif'ов

Код:

using System;
using System.Drawing;
using System.Windows.Forms;

public class animateImage : Form
{

//Create a Bitmpap Object.
Bitmap animatedImage = new Bitmap("SampleAnimation.gif");
bool currentlyAnimating = false;

//This method begins the animation.
public void AnimateImage()
{
if (!currentlyAnimating)
{

//Begin the animation only once.
ImageAnimator.Animate(animatedImage, new EventHandler(this.OnFrameChanged));
currentlyAnimating = true;
}
}

private void OnFrameChanged(object o, EventArgs e)
{

//Force a call to the Paint event handler.
this.Invalidate();
}

protected override void OnPaint(PaintEventArgs e)
{

//Begin the animation.
AnimateImage();

//Get the next frame ready for rendering.
ImageAnimator.UpdateFrames();

//Draw the next frame in the animation.
e.Graphics.DrawImage(this.animatedImage, new Point(0, 0));
}

public static void Main()
{
Application.Run(new animateImage());
}
}
