我是 WPF 技术的新手。我在 WPF 中有以下窗口声明:

<Window x:Class="CustomWindows.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="480" Width="640" ScrollViewer.VerticalScrollBarVisibility="Disabled" WindowStyle="None" AllowsTransparency="True">
    <Window.Effect>
        <DropShadowEffect BlurRadius="15" Direction="-90" RenderingBias="Quality" ShadowDepth="2"/>
    </Window.Effect>
    <Grid>

    </Grid>
</Window>

但是当我运行它时,阴影不会出现。我能做什么,或者错误在哪里?

DropShadowEffect不能应用于Window. 相反,如果要覆盖默认窗口外观,则必须将效果应用于窗口中包含的其他一些元素:

<Window x:Class="WpfApplication2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" WindowStyle="None"
        AllowsTransparency="True" Background="Transparent">

    <Grid Margin="20" Background="Red">
        <Grid.Effect>
            <DropShadowEffect BlurRadius="15" Direction="-90"
                              RenderingBias="Quality" ShadowDepth="2"/>
        </Grid.Effect>
        ...
      
    </Grid>
</Window>
