No applicable name scope exists to resolve the name

写了一个 Storyboard ，如下：

 DoubleAnimation crossLeftAnimation = new DoubleAnimation();
                        crossLeftAnimation.Duration = TimeSpan.FromSeconds(0.5);
 
                        Storyboard.SetTargetName(crossLeftAnimation, "imgCrossCartoon");
                        Storyboard.SetTargetProperty(crossLeftAnimation,
                                new PropertyPath(Canvas.LeftProperty));
 
                        DoubleAnimation crossTopAnimation = new DoubleAnimation();
                        crossTopAnimation.Duration = TimeSpan.FromSeconds(0.5);
 
                        Storyboard.SetTargetName(crossTopAnimation, "imgCrossCartoon");
                        Storyboard.SetTargetProperty(crossTopAnimation,
                                new PropertyPath(Canvas.TopProperty));
 
                        Storyboard myStoryboard=new Storyboard();
                        myStoryboard.Completed+=new EventHandler(myStoryboard_Completed);
 
                        this.imgCrossCartoon.IsEnabled= true;
 
                        if (id > )
                        {
                            crossLeftAnimation.From = Canvas.GetLeft(_calibrateCircles[id-]);
                            crossLeftAnimation.To = Canvas.GetLeft(_calibrateCircles[id]);
 
                            crossTopAnimation.From = Canvas.GetTop(_calibrateCircles[id - ]);
                            crossTopAnimation.To = Canvas.GetTop(_calibrateCircles[id]);
                        }
                        else
                        {
                            crossLeftAnimation.From = -;
                            crossLeftAnimation.To = Canvas.GetLeft(_calibrateCircles[id]);
 
                            crossTopAnimation.From = -;
                            crossTopAnimation.To = Canvas.GetTop(_calibrateCircles[id]);
                        }
 
                        myStoryboard.Children.Add(crossLeftAnimation);
                        myStoryboard.Children.Add(crossTopAnimation);
                        myStoryboard.Begin();

结果出现：Storyboard 不存在可解析名称“ ”的适用名称领域错误。后来参考http://social.msdn.microsoft.com/Forums/zh-TW/802/thread/1365449e-965d-4df7-82df-e3e0e8d0ca19，把最后一句改为：

myStoryboard.Begin(this.imgCrossCartoon);

就好了。

另外 如果非得用myStoryboard.Begin(),请在XAML Storyboard 下面的元素中添加     Storyboard.Target="{x:Reference Name=RootElement}"  (这个比较有效) 或者   Storyboard.Target="{Binding ElementName=xxxxx}"
