　　StoryBoard使用，Xaml转cs代码

< Canvas.Triggers>
                < EventTrigger RoutedEvent= "Image.MouseLeftButtonDown">
                    < EventTrigger.Actions>
                        < BeginStoryboard>
                            < Storyboard Storyboard.TargetName= "image1"  
                                                Storyboard.TargetProperty= "(Canvas.Left)"  >
                                < DoubleAnimation AutoReverse= "True"  
RepeatBehavior= "Forever"  
                                                         BeginTime= "0"  
Duration= "0:0:20"  From= "0"  To= "-1100">
                                < /DoubleAnimation>
                            < /Storyboard>
                        < /BeginStoryboard>
                    < /EventTrigger.Actions>
                < /EventTrigger>
            < /Canvas.Triggers>

 

　　转换为cs代码：

          this.image1.RenderTransform =  new TranslateTransform();

             this.image1.Name =  "image1";
            NameScope.SetNameScope( this, new NameScope());
             this.RegisterName( this.image1.Name, this.image1);

            DoubleAnimation xAnimation =  new DoubleAnimation();
            xAnimation.From = 0;
            xAnimation.To = -1100;
            xAnimation.Duration =  new Duration(TimeSpan.FromSeconds(30));

            DependencyProperty[] propertyChain =  new DependencyProperty[]
            {
                Image.RenderTransformProperty,
                TranslateTransform.XProperty
            };

            Storyboard story =  new Storyboard();
            story.AutoReverse =  true;
            story.RepeatBehavior = RepeatBehavior.Forever;
            story.Children.Add(xAnimation);

            Storyboard.SetTargetName(xAnimation, this.image1.Name);
            Storyboard.SetTargetProperty(xAnimation, new PropertyPath( "(0).(1)",propertyChain));

            story.Begin( this);
