我在用 Win7 编写的 WPF 中设置了列表框的样式所以我的风格是

<ListBox>
 <ListBox.Resources>
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#3399FF" />
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="#000000" />
     <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="#3399FF" />
     <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}" Color="#000000" />
 </ListBox.Resources>
</ListBox>

此代码在焦点和散焦状态下对列表框项进行相同的选择。当我在 Windows 8 下运行我的程序时，这种外观不起作用。我的代码哪里出错了？

ListBoxItem在 Windows-8 中似乎有

<MultiTrigger>
  <MultiTrigger.Conditions>
    <Condition Property="IsSelected" Value="true"/>
    <Condition Property="Selector.IsSelectionActive" Value="false"/>
  </MultiTrigger.Conditions>
  <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}"/>
  <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
</MultiTrigger>

因为它是默认样式中的非活动选择触发器，然后使用它SystemColors.ControlBrushKey，SystemColors.ControlTextBrushKey因此您可能也希望在资源中覆盖它们，

也许是这样的：

<ListBox>
 <ListBox.Resources>
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#3399FF" />
     <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="#000000" />
     <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="#3399FF" />
     <SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="#000000" />
     <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="#3399FF" />
     <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}" Color="#000000" />
 </ListBox.Resources>
</ListBox>

或者只是自己创建一个Style（基于默认模板）并直接在这个新的上设置颜色Style，然后保证适用于任何版本的操作系统，您不必继续回溯并检查是否有任何更改默认值。

尝试使用 ItemTemplate 作为：

 <ListBox HorizontalContentAlignment="Stretch">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <Label  Margin="-5, -2,-5,-2" Content="{Binding Item}">
                            <Label.Style>
                                <Style TargetType="Label">
                                    <Style.Triggers>
                                        <MultiDataTrigger>
                                            <MultiDataTrigger.Conditions>
                                                <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBox}},Path=IsFocused}" Value="False"/>
                                                <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="True"/>
                                            </MultiDataTrigger.Conditions>
                                            <Setter Property="Background" Value="CornflowerBlue"/>
                                        </MultiDataTrigger>
                                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="True">
                                            <Setter Property="Foreground" Value="White"/>
                                        </DataTrigger>
                                        <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="False">
                                            <Setter Property="Foreground" Value="Black"/>
                                        </DataTrigger>
                                    </Style.Triggers>
                                </Style>
                            </Label.Style>
                        </Label>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
