您的路径资源不正确，请将其替换为：
<Path.Resources>
<Style TargetType="{x:Type Path}">
<Setter Property="Fill" Value="#FFFFFFFF" />
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=StackPanel,AncestorLevel=1}, Path=IsMouseOver}" Value="True" >
<Setter Property="Fill" Value="{Binding MouseOverColor}" />
</DataTrigger>
</Style.Triggers>
</Style>

Background=“#01000000”注意。您的路径资源不正确，请将其替换为：

Background=“#01000000”注意。试试这个：在我的例子中，stackpanel作为AncestorType不起作用，所以我使用了Menuitem
