在我们的 Metro Style 应用程序中，我正在使用一个列表框并希望自定义它的滚动条，这意味着滚动条的高度、宽度和颜色（水平和垂直）。有没有做这个任务的例子？我进行了很多搜索，但找不到示例。请帮助。

您需要先自定义您自己的ScrollViewer，然后将其添加到ListBox. 下面是ListBox的默认样式，之后是ScrollViewer默认样式。

<Style TargetType="ListBox">
  <Setter Property="Foreground" Value="{StaticResource ListBoxForegroundThemeBrush}" />
  <Setter Property="Background" Value="{StaticResource ListBoxBackgroundThemeBrush}" />
  <Setter Property="BorderBrush" Value="{StaticResource ListBoxBorderThemeBrush}" />
  <Setter Property="BorderThickness" Value="{StaticResource ListBoxBorderThemeThickness}" />
  <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" />
  <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" />
  <Setter Property="ScrollViewer.HorizontalScrollMode" Value="Disabled" />
  <Setter Property="ScrollViewer.IsHorizontalRailEnabled" Value="True" />
  <Setter Property="ScrollViewer.VerticalScrollMode" Value="Enabled" />
  <Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="True" />
  <Setter Property="ScrollViewer.ZoomMode" Value="Disabled" />
  <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False" />
  <Setter Property="ScrollViewer.BringIntoViewOnFocusChange" Value="True" />
  <Setter Property="IsTabStop" Value="False" />
  <Setter Property="TabNavigation" Value="Once" />
  <Setter Property="FontFamily" Value="{StaticResource ContentControlThemeFontFamily}" />
  <Setter Property="FontSize" Value="{StaticResource ControlContentThemeFontSize}" />
  <Setter Property="ItemsPanel">
    <Setter.Value>
      <ItemsPanelTemplate>
        <VirtualizingStackPanel />
      </ItemsPanelTemplate>
    </Setter.Value>
  </Setter>
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="ListBox">
