以下代码在 Silverlight 中运行良好:

private void Button_Click_1(object sender, RoutedEventArgs e)
{    
    Storyboard storyboard = new Storyboard();
    DoubleAnimation doubleAnimation = new DoubleAnimation();
    doubleAnimation.From = 50;
    doubleAnimation.To = 100;
    doubleAnimation.RepeatBehavior = RepeatBehavior.Forever;
    doubleAnimation.AutoReverse = true;
    doubleAnimation.Duration = new Duration(TimeSpan.FromMilliseconds(200));
    storyboard.Children.Add(doubleAnimation);
    Storyboard.SetTarget(doubleAnimation, button1);
    Storyboard.SetTargetProperty(doubleAnimation, new PropertyPath("Width"));
    storyboard.Begin();
}

在 WinRT/Metro 中,它需要做一个小改动才能使其编译:

Storyboard.SetTargetProperty(doubleAnimation, "Width");

但是当你运行它时,什么也没有发生。

如果您将属性从“Width”更改为“Opacity”(同时更改 From=0 和 To=1),则可以。

“宽度”有什么问题?

您需要添加以下内容:

doubleAnimation.EnableDependentAnimation = true;

这似乎可以解决问题。

我不确定,但尝试使用:

Storyboard.SetTargetProperty(doubleAnimation, Button.WidthProperty);

代替

Storyboard.SetTargetProperty(doubleAnimation, "Width");
