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,或者在哪里发生错误?

DropShadowEffect
无法应用于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>
