你可以从Expression Blend中获得它：

<Style TargetType="{x:Type GroupBox}">
        <Setter Property="BorderBrush" Value="#D5DFE5"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type GroupBox}">
                    <Grid SnapsToDevicePixels="true">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="6"/>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="6"/>
                        </Grid.ColumnDefinitions>
