如何有一个圆角矩形的单边边框？

Question

我想要任何边框控件的单边边框，例如此处左侧的蓝色边栏：。渐变要么不起作用，要么我遗漏了一些关于它们的信息。是否有可实施的解决方案？

Answer 1

我做了一个小样：

    <Border x:Name="MainBorder" Padding="0,20,0,20" CornerRadius="10,10,10,10" Background="LightGray" HorizontalAlignment="Left" VerticalAlignment="Top">
        <StackPanel Orientation="Horizontal">
            <Border x:Name="SideBorder" BorderThickness="5,5,5,5" CornerRadius="1,1,1,1" BorderBrush="Blue" Height="50" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,8,0,0"></Border>
            <TextBlock x:Name="TestBlock" Text="Text" Margin="50,0,150,0" FontSize="48" HorizontalAlignment="Center" VerticalAlignment="Center"></TextBlock>
        </StackPanel>
    </Border>
