How do I change RichTextBox paragraph spacing?
提问by Darren Oster
I am using a RichTextBox in WPF, and am trying to set the default paragraph spacing to 0 (so that there is no paragraph spacing). While I could do this in XAML, I would like to achieve it programmatically if possible. Any ideas?
我在 WPF 中使用 RichTextBox，并尝试将默认段落间距设置为 0（以便没有段落间距）。虽然我可以在 XAML 中做到这一点，但如果可能的话，我想以编程方式实现它。有任何想法吗？

I did it with style(pun indented)
我用风格做到了（双关缩进）
<RichTextBox Margin="0,51,0,0" Name="mainTextBox" >
<RichTextBox.Resources>
<Style TargetType="{x:Type Paragraph}">
<Setter Property="Margin" Value="0"/>
</Style>
</RichTextBox.Resources>
</RichTextBox>

Using Line Height
使用行高
RichTextBox rtb = new RichTextBox();
Paragraph p = rtb.Document.Blocks.FirstBlock as Paragraph;
p.LineHeight = 10;

Close, so you got the points. Actually it turned out to be setting the margin,
关闭，所以你得到了积分。其实原来是设置边距，
p.Margin = new Thickness(0);

For me on VS2017 in WPF works this:
对我来说，WPF 中的 VS2017 是这样工作的：
<RichTextBox HorizontalAlignment="Left" Height="126" Margin="10,280,0,0" VerticalAlignment="Top" Width="343" FontSize="14" Block.LineHeight="2"/>
The key is Block.LineHeight="2"
关键是Block.LineHeight="2"
You can found this also in Properties view but you can't change below 6px from there.
您也可以在“属性”视图中找到它，但不能从那里更改低于 6px。

RichTextBox rtb = new RichTextBox();
rtb.SetValue(Paragraph.LineHeightProperty, 1.0);
