C# 未应用列表框项目样式

我正在尝试为我的ListBoxItem创建一个样式，但是没有应用该样式

谁能告诉我怎么了

代码：

<ListBox>
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <VirtualizingStackPanel IsItemsHost="True" Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test1" Foreground="Gray"/>
    <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test2" Foreground="Gray"/>
</ListBox>

<Style x:Key="MyListStyle" TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="Transparent"></Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Foreground" Value="Black" />
            </Trigger>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Foreground" Value="White"/>
            </Trigger>
        </Style.Triggers>
</Style>

XAML:

<ListBox>
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <VirtualizingStackPanel IsItemsHost="True" Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test1" Foreground="Gray"/>
    <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test2" Foreground="Gray"/>
</ListBox>

<Style x:Key="MyListStyle" TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="Transparent"></Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Foreground" Value="Black" />
            </Trigger>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Foreground" Value="White"/>
            </Trigger>
        </Style.Triggers>
</Style>

风格：

<ListBox>
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <VirtualizingStackPanel IsItemsHost="True" Orientation="Horizontal"/>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
    <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test1" Foreground="Gray"/>
    <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test2" Foreground="Gray"/>
</ListBox>

<Style x:Key="MyListStyle" TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="Transparent"></Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Foreground" Value="Black" />
            </Trigger>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Foreground" Value="White"/>
            </Trigger>
        </Style.Triggers>
</Style>

因为WPF属性的优先级从高到低排列

因此，您的ListBoxItem.前台是本地设置，高于其他设置

 <ListBoxItem Style="{StaticResource MyListStyle}" Content="Test2" Foreground="Gray"/>

您可以删除

<ListBoxItem Style="{StaticResource MyListStyle}" Content="Test2"/>

并以静态资源样式设置前景

<Style x:Key="MyListStyle" TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="Transparent"></Setter>
        <Setter Property="Foreground" Value="Gray"></Setter>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Foreground" Value="Black" />
            </Trigger>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Foreground" Value="White"/>
            </Trigger>
        </Style.Triggers>
    </Style>

您可以在中找到优先级列表

还有一个问题，如何从盒子中去除蓝色效果？此属性的名称可以显示最终效果吗？在MyListStyle静态资源中尝试蓝色框仍然出现确定我看到了，要删除选择突出显示，请在此处回答
