C# c wpf在加载时将DoubleAnimation更改为（在中）

我使用此代码从左到右设置图像动画 但我想把窗户宽度设为=100 如何在加载或调整窗口大小时将DoubleAnimation更改为

xaml：

如果我正确理解了您的问题，您希望在codebehind中将to更改为不同的值，如下所示：

Storyboard sb = this.FindResource("PlayAnimation") as Storyboard;        
(sb.Children[0] as DoubleAnimation).To = 200;
Storyboard.SetTarget(sb, this.image2);
sb.Begin();

private void Window_Loaded(object sender, RoutedEventArgs e)
{
  Storyboard sb = this.FindResource("PlayAnimation") as Storyboard;        
  Storyboard.SetTarget(sb, this.image2);
  sb.Begin();
}

Storyboard sb = this.FindResource("PlayAnimation") as Storyboard;        
(sb.Children[0] as DoubleAnimation).To = 200;
Storyboard.SetTarget(sb, this.image2);
sb.Begin();
