ListBox의 선택된 항목 색상을 변경할 수 있습니까?

Question

그래서,이 ListBox가 XAML로 작성이 : 나는 배경, 전경의 색상 및 목록 상자 항목의 텍스트를 변경할 수

<ListBox Margin="0" x:Name="ListBox_Main" Grid.Row="1" VerticalAlignment="Top" FontSize="24" SelectionChanged="ListBox_Main_SelectionChanged" Foreground="Black"> 
    <ListBoxItem Content="Item 1" Background="#19000000" /> 
    <ListBoxItem Content="Item 2" Background="#19000000" /> 
    <ListBoxItem Content="Item 3" Background="#19000000" /> 
    <ListBoxItem Content="Item 4" Background="#19000000"/> 
    <ListBoxItem Content="Item 5" Background="#19000000"/> 
</ListBox> 

하지만 색상을 변경하는 옵션이 없을 때 항목의 가 선택되면 기본적으로 파란색입니다.

푸른 색을 바꿀 수 있습니까?

귀하의 요구 사항에 따라 ListBoxItem의 기본 스타일 템플릿을 변경해야합니다. MSDN Reference

<Style TargetType="ListBoxItem"> 
    <Setter Property="Padding" Value="3" /> 
    <Setter Property="HorizontalContentAlignment" Value="Left" /> 
    <Setter Property="VerticalContentAlignment" Value="Top" /> 
    <Setter Property="Background" Value="Transparent" /> 
    <Setter Property="BorderThickness" Value="1"/> 
    <Setter Property="TabNavigation" Value="Local" /> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="ListBoxItem">
