如何使段落角变圆？

Question

我有一个富文本框，我可以（动态地）向其中添加段落，我想在添加段落时使段落边框变圆，我该怎么做？这是我的代码：

    <Grid>
    <RichTextBox x:Name="richTextBox" HorizontalAlignment="Left" Height="315" Margin="10,10,0,0" VerticalAlignment="Top" Width="312" IsReadOnly="True" >
        <FlowDocument x:Name="flowDocument" >

        </FlowDocument>
    </RichTextBox>
</Grid>

我尝试访问段落边框属性，但我做不到。
我的代码中有这样的内容：

Paragraph p = new Paragraph(new Run("Some text"));
p.BorderBrush = Brushes.Black;
p.BorderThickness = new Thickness(1);
//Make the paragraph border round
flowDoucment.Blocks.Add(p);

知道如何设置边框的 CornerRadius 属性吗？

Answer 1

您可以通过以下方式进行：

<Border Height="315" Width="312" BorderBrush="Bisque"  VerticalAlignment="Top"  Margin="10,10,0,0" HorizontalAlignment="Left"   BorderThickness="2" CornerRadius="20">
        <RichTextBox x:Name="richTextBox"  Height="315"  VerticalAlignment="Bottom" BorderThickness="0"   Width="312" IsReadOnly="True" >

        </RichTextBox>
    </Border>
    <Border Height="315" Width="312" BorderBrush="Bisque"  VerticalAlignment="Top"  Margin="10,10,0,0" HorizontalAlignment="Left"   BorderThickness="2" CornerRadius="20" />

Answer 2

您可以使用 BlockUIContainer 并在其中再添加一个 RichTextBox 来实现它。参考下面的代码。

<RichTextBox>
        <FlowDocument>  
            <BlockUIContainer>
                <Border BorderThickness="2" BorderBrush="Blue" CornerRadius="8" Padding="3"> 
                    <RichTextBox  BorderThickness="0">
                        <FlowDocument>
                            <Paragraph>This is paragraph with border</Paragraph>
                        </FlowDocument>
                    </RichTextBox>                        
                </Border>
            </BlockUIContainer>    
        </FlowDocument>
    </RichTextBox>
