如何在Code中编写这个XAML Storyboard？

Question

<Storyboard x:Key="CloseContentGrid">
    <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Height" Storyboard.TargetName="ContentGrid">
        <EasingDoubleKeyFrame KeyTime="0" Value="100"/>
        <EasingDoubleKeyFrame KeyTime="0:0:0.8" Value="0"/>
    </DoubleAnimationUsingKeyFrames>
</Storyboard>

我想使用此动画将网格的Height从ActualHeight(100)更改为Zero

Answer 1

你可以试试这个：

DoubleAnimation animation = new DoubleAnimation(100,0, new Duration(TimeSpan.FromMilliseconds(800)));
ContentGrid.BeginAnimation(HeightProperty, animation);
