有谁知道是否可以对 app.current.mainwindow.width 进行动画处理，以便在以编程方式调整 oob 应用程序窗口大小时获得一个带有缓动的漂亮动画。谢谢。

最简单的方法是向页面添加滑块控件。滑块可以折叠，仅用于具有简单的动画属性。对滑块的 Value 属性进行动画处理。在滑块的 ValueChanged 事件中更新窗口宽度。你需要增加推力才能做到这一点。

它看起来像这样：

Xaml

<UserControl.Resources>
  <Storyboard x:Name="Storyboard1">
    <DoubleAnimation Duration="0:0:1" To="750" 
                     Storyboard.TargetProperty="(RangeBase.Value)" 
                     Storyboard.TargetName="slider1">
      <DoubleAnimation.EasingFunction>
        <BounceEase EasingMode="EaseOut"/>
      </DoubleAnimation.EasingFunction>
    </DoubleAnimation>
  </Storyboard>    
</UserControl.Resources>

<Grid x:Name="LayoutRoot" Background="Green">
  <Button Width="50" Height="32" Click="Button_Click">Test</Button>
  <Slider Visibility="Collapsed" VerticalAlignment="Bottom" 
          x:Name="slider1" Maximum="1000" 
          ValueChanged="slider1_ValueChanged" />
</Grid>

代码隐藏

private void Button_Click(object sender, RoutedEventArgs e)
{
    Storyboard1.Begin();
}

private void slider1_ValueChanged(object sender, 
                                  RoutedPropertyChangedEventArgs<double> e)
{
    Application.Current.MainWindow.Width = e.NewValue;
}

The simplest way is to add a slider control to your page. The slider can be collapsed and is only used to have an easy propery to animate. Animate the Value property of the slider. In the ValueChanged event of the slider update the window width. You need elevated thrust to do this.

It looks something like this:

Xaml

<UserControl.Resources>
  <Storyboard x:Name="Storyboard1">
    <DoubleAnimation Duration="0:0:1" To="750" 
                     Storyboard.TargetProperty="(RangeBase.Value)" 
                     Storyboard.TargetName="slider1">
      <DoubleAnimation.EasingFunction>
        <BounceEase EasingMode="EaseOut"/>
      </DoubleAnimation.EasingFunction>
    </DoubleAnimation>
  </Storyboard>    
</UserControl.Resources>

<Grid x:Name="LayoutRoot" Background="Green">
  <Button Width="50" Height="32" Click="Button_Click">Test</Button>
  <Slider Visibility="Collapsed" VerticalAlignment="Bottom" 
          x:Name="slider1" Maximum="1000" 
          ValueChanged="slider1_ValueChanged" />
</Grid>

Code Behind

private void Button_Click(object sender, RoutedEventArgs e)
{
    Storyboard1.Begin();
}

private void slider1_ValueChanged(object sender, 
                                  RoutedPropertyChangedEventArgs<double> e)
{
    Application.Current.MainWindow.Width = e.NewValue;
}
