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);
