WPF实现左右移动（晃动）动画效果

原文:WPF实现左右移动（晃动）动画效果

实现控件或布局的左右移动（晃动）主要用到DoubleAnimation以及Storyboard

布局代码为：

<Canvas>

        <Grid Width="200" Height="100" Background="MediumAquamarine" Name="GroupboxArea" Canvas.Left="100" Canvas.Top="200"/>

        <Button Content="Button" Height="25" Width="78" Click="Button_Click"/>

    </Canvas>

后台代码为:

 private void Button_Click(object sender, RoutedEventArgs e)

        {

            DoubleAnimation DAnimation = new DoubleAnimation();

            DAnimation.From = 100;//起点

            DAnimation.To = 280;//终点

            DAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));//时间

            Storyboard.SetTarget(DAnimation, GroupboxArea);

            Storyboard.SetTargetProperty(DAnimation, new PropertyPath(Canvas.LeftProperty));

            Storyboard story = new Storyboard();

            story.Completed += new EventHandler(story_Completed);//完成后要做的事

            //story.RepeatBehavior = RepeatBehavior.Forever;//无限次循环，需要的自己加上

            story.Children.Add(DAnimation);

            story.Begin();

        }

        void story_Completed(object sender, EventArgs e)

        {

            DoubleAnimation DAnimation = new DoubleAnimation();

            DAnimation.From = 280;//起点

            DAnimation.To = 100;//终点

            DAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));//时间

            Storyboard.SetTarget(DAnimation, GroupboxArea);

            Storyboard.SetTargetProperty(DAnimation, new PropertyPath(Canvas.LeftProperty));

            Storyboard story = new Storyboard();

            story.Completed += new EventHandler(storyCompleted);//完成后要做的事

            //story.RepeatBehavior = RepeatBehavior.Forever;//无限次循环，需要的自己加上

            story.Children.Add(DAnimation);

            story.Begin();

        }

        void storyCompleted(object sender, EventArgs e)

        {

            DoubleAnimation DAnimation = new DoubleAnimation();

            DAnimation.From = 100;//起点

            DAnimation.To = 200;//终点

            DAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));//时间

            Storyboard.SetTarget(DAnimation, GroupboxArea);

            Storyboard.SetTargetProperty(DAnimation, new PropertyPath(Canvas.LeftProperty));

            Storyboard story = new Storyboard();

            //story.Completed += new EventHandler(storyCompleted);//完成后要做的事

            //story.RepeatBehavior = RepeatBehavior.Forever;//无限次循环，需要的自己加上

            story.Children.Add(DAnimation);

            story.Begin();

        }
