可以改变ListBoxItem的style来改变选择高亮颜色.'Selected' 关键字将填充属性更改为您想要的颜色(我将颜色更改为如下所示的红色).

You can change the style of ListBoxItem to change the selection highlight color.In the style,you should change all the states that contanin 'Selected' key word to change the Fill property to the color you want(I change the color to the Red like below).

<Style x:Key="ListBoxItemStyle1" TargetType="ListBoxItem">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="TabNavigation" Value="Local"/>
    <Setter Property="Padding" Value="{StaticResource ListBoxItemPadding}"/>
    <Setter Property="HorizontalContentAlignment" Value="Left"/>
    <Setter Property="UseSystemFocusVisuals" Value="{StaticResource UseSystemFocusVisuals}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ListBoxItem">
                <Grid x:Name="LayoutRoot" Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}">
                    <Grid.Resources>
                        <Style x:Key="BaseContentPresenterStyle" TargetType="ContentPresenter">
                            <Setter Property="FontFamily" Value="XamlAutoFontFamily"/>
                            <Setter Property="FontWeight" Value="SemiBold"/>
                            <Setter Property="TextWrapping" Value="Wrap"/>
                            <Setter Property="LineStackingStrategy" Value="MaxHeight"/>
                            <Setter Property="TextLineBounds" Value="Full"/>
                            <Setter Property="OpticalMarginAlignment" Value="TrimSideBearings"/>
                        </Style>
                        <Style x:Key="BodyContentPresenterStyle" BasedOn="{StaticResource BaseContentPresenterStyle}" TargetType="ContentPresenter">
                            <Setter Property="FontWeight" Value="Normal"/>
                        </Style>
                    </Grid.Resources>
                    <VisualStateManager.VisualStateGroups>

                                        <DiscreteObjectKeyFrame KeyTime="0" Value="Red"/>

                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                    <Rectangle x:Name="PressedBackground" Fill="Transparent" Control.IsTemplateFocusTarget="True"/>
                    <ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" Style="{StaticResource BodyContentPresenterStyle}" TextWrapping="NoWrap" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后将样式设置为 ListBox.

Then set the style to the ListBox.

<ListBox Width="100" ItemContainerStyle="{StaticResource ListBoxItemStyle1}">
