WPF : StoryBoard用法

Storyboard storyBoard = new Storyboard();
DoubleAnimation ani = new DoubleAnimation();
           
ani.From = 0;
ani.To = 360;
ani.Duration = new Duration(TimeSpan.FromMilliseconds(5000));
ani.RepeatBehavior = RepeatBehavior.Forever;
storyBoard.Children.Add(ani);

this.RegisterName("mRotationX", mRotationX);
Storyboard.SetTargetName(ani, "mRotationX");
Storyboard.SetTargetProperty(ani, new PropertyPath(AxisAngleRotation3D.AngleProperty));
storyBoard.Begin(this, true); /////true表示controlable

            TimeSpan timeSpan = TimeSpan.FromMilliseconds(250);

            //创建一个Animation, 设置起点, 终点, 时段
            DoubleAnimation ani = new DoubleAnimation();
            ani.From = 4;
            ani.To = 0;
            ani.Duration = new Duration(timeSpan);           
            Storyboard.SetTargetName(ani, "Opacity");
            Storyboard.SetTargetProperty(ani, new PropertyPath(WindowMain.OpacityProperty));

            //创建一个Animation, 设置起点, 终点, 时段
            DoubleAnimation ani2 = new DoubleAnimation();
            ani2.From = this.mZoomSlider.Value;
            ani2.To = 2;
            ani2.Duration = new Duration(timeSpan);           
            Storyboard.SetTargetName(ani2, "Zoom");
            Storyboard.SetTargetProperty(ani2, new PropertyPath(Slider.ValueProperty));


            //创建StoryBoard
            Storyboard storyBoard = new Storyboard();
              storyBoard.FillBehavior = FillBehavior.Stop;
            storyBoard.Completed += new EventHandler(storyBoard_Completed);
            storyBoard.Children.Add(ani);
            storyBoard.Children.Add(ani2);

            this.RegisterName("Opacity", this);
            this.RegisterName("Zoom", this.mZoomSlider);           
            storyBoard.Begin(this, true); /////////////////////////////////true表示controlable
