I did it with style (pun indented)

<RichTextBox  Margin="0,51,0,0" Name="mainTextBox" >
        <RichTextBox.Resources>
            <Style TargetType="{x:Type Paragraph}">
                <Setter Property="Margin" Value="0"/>
            </Style>
        </RichTextBox.Resources>
    </RichTextBox>

Answer 2

<RichTextBox  Height="250" Width="500" VerticalScrollBarVisibility="Auto" TextWrapping="Wrap" IsReadOnly="True" >
    <Paragraph>
        XYZ
        <LineBreak />
    </Paragraph>
</RichTextBox>

Answer 3

Close, so you got the points. Actually it turned out to be setting the margin,

p.Margin = new Thickness(0);

Answer 4

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

Answer 5

Using Line Height

RichTextBox rtb = new RichTextBox();    
Paragraph p = rtb.Document.Blocks.FirstBlock as Paragraph;    
p.LineHeight = 10;

Answer 6

In C# 2008 WAP

richtextbox1.SelectionCharOffset =
    -1 * ( Convert.ToInt32(R223.Txt_Space_Before.Text) * 100);

or

richtextbox1.SelectionCharOffset =
    Convert.ToInt32(R223.Txt_Space_Before.Text) * 100;

can be used for Line Spacing.

This is the only way you can have line height spacing.
