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

        }
        private void OnFrameChanged(object o, EventArgs e)
        {
//Invalidate the window to force a call to the paint event handler.
//if we had more items in the window than just the animation,we coule 
//invalidate just the area occupied by the animation.
            this.Invalidate();
        }
    }
}
//为了使这个例子运行起来,加载的文件必须是一个GIF动画.
