如何在不从材料设计中删除样式的情况下更改SelectedItem的前景色？

这可行，但将从材料设计中删除样式：

<ListBox TextElement.Foreground="Black">
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel IsItemsHost="True" />
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemContainerStyle>
                <Style TargetType="ListBoxItem">
                    <Style.Triggers>
                        <Trigger Property="IsSelected" Value="True" >
                            <Setter Property="FontWeight" Value="Bold" />
                            <Setter Property="Background" Value="Transparent" />
                            <Setter Property="Foreground" Value="White" />
                        </Trigger>
                    </Style.Triggers>
                    <Style.Resources>
                        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
                    </Style.Resources>
                </Style>
            </ListBox.ItemContainerStyle>
        </ListBox>

将样式更改为BasedOn =“ {StaticResource MaterialDesignListBoxItem}”

 <ListBox.ItemContainerStyle>
       <Style TargetType="ListBoxItem" BasedOn="{StaticResource MaterialDesignListBoxItem}">
                    <Style.Triggers>
                        <Trigger Property="IsSelected" Value="True" >
                            <Setter Property="FontWeight" Value="Bold" />
                            <Setter Property="Background" Value="Transparent" />
                            <Setter Property="Foreground" Value="White" />                               
                        </Trigger>
                    </Style.Triggers>
                    <Style.Resources>
                        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
                    </Style.Resources>
      </Style>
 </ListBox.ItemContainerStyle>
