How to stop image animation in Windows Forms application after some seconds using C# .Net

how can we stop any animated picture on form load event in windows form application. Actually, i want to start animated motion on button click and after 5 sec it should stop autometically .

i tried with this code but didn't work.

System.Drawing.ImageAnimator.Animate(pictureBox1.Image, OnFrameChanged);

            System.Threading.Thread.Sleep(5000);
            System.Drawing.ImageAnimator.StopAnimate(pictureBox1.Image, OnFrameChanged);

and on form load :

System.Drawing.ImageAnimator.Animate(pictureBox1.Image, OnFrameChanged);
