您应该像这样设置宽度和高度属性：

        DoubleAnimation widthAnimation = new DoubleAnimation
        {
            From = 0,
            To = rect1.ActualWidth*2,
            Duration = TimeSpan.FromSeconds(5)
        };

        DoubleAnimation heightAnimation = new DoubleAnimation
        {
            From = 0,
            To = rect1.ActualHeight*2,
            Duration = TimeSpan.FromSeconds(5)
        };

        Storyboard.SetTargetProperty(widthAnimation, new PropertyPath(Rectangle.WidthProperty));
        Storyboard.SetTarget(widthAnimation, rect1);

        Storyboard.SetTargetProperty(heightAnimation, new PropertyPath(Rectangle.HeightProperty));
        Storyboard.SetTarget(heightAnimation, rect1);

        Storyboard buttonEnlargeStoryboard = new Storyboard();
        buttonEnlargeStoryboard.SpeedRatio = 1;
        buttonEnlargeStoryboard.Children.Add(widthAnimation);
        buttonEnlargeStoryboard.Children.Add(heightAnimation);
        buttonEnlargeStoryboard.Begin();
