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
