问题描述

DoubleAnimation不包含采用“3”个参数的构造函数

         Storyboard storyboard = new Storyboard();        DoubleAnimation doubleAnimation = new DoubleAnimation(Canvas.GetLeft(rect) p.X new Duration(TimeSpan.FromMilliseconds(500)));        Storyboard.SetTarget(doubleAnimation rect);        Storyboard.SetTargetProperty(doubleAnimation new PropertyPath(""(Canvas.Left)""));        storyboard.Children.Add(doubleAnimation);        //创建Y轴方向动画        doubleAnimation = new DoubleAnimation(          Canvas.GetTop(rect)          p.Y          new Duration(TimeSpan.FromMilliseconds(500))        );        Storyboard.SetTarget(doubleAnimation rect);        Storyboard.SetTargetProperty(doubleAnimation new PropertyPath(""(Canvas.Top)""));        storyboard.Children.Add(doubleAnimation);        storyboard.Begin();

为什么报错“System.Windows.Media.Animation.DoubleAnimation”不包含采用“3”个参数的构造函数
