提问by deerchao
I'd like to hide the border of ListBox, and make background of selected item the same as unselected ones.

To hide the border, use
要隐藏边框，请使用
<ListBox BorderThickness="0"/>
If you don't want to have a selection, use an ItemsControlinstead of the ListBox.
如果您不想进行选择，请使用ItemsControl代替ListBox。
The following code hides the border around the ListBox and does always show a white background on the item (if its generated through the ItemsSource-property).
以下代码隐藏了 ListBox 周围的边框，并且始终在项目上显示白色背景（如果它是通过ItemsSource-property生成的）。
<ListBox BorderThickness="0" HorizontalContentAlignment="Stretch">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Padding" Value="0"/>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<Grid Background="White">
<ContentPresenter Content="{Binding}"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
If you use ListViewItem-instances, you must change the background there.
如果您使用 ListViewItem-instances，则必须更改那里的背景。

In the meantime I have found a solution that is IMO much more elegant:
与此同时，我找到了一个更优雅的 IMO 解决方案：
<ListBox BorderThickness="0" HorizontalContentAlignment="Stretch" >
<ListBox.Resources>
<Style TargetType="ListBoxItem">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent"/>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black"/>
</Style.Resources>
</Style>
</ListBox.Resources>
</ListBox>
This should work also with ListBoxItem-instances and is IMO less "work-around".
这也应该适用于 ListBoxItem-instances，并且 IMO 较少“变通”。
