我是一个C# WPF的初学者，我想通过编程制作一个只有几段的流程文档。问题是，有一个大的空间之间的pagraphs，我想调整它的最小值。
我通过使用Xml语句找到了一个解决方案，但我想通过编程来实现它：

<FlowDocument>
  <FlowDocument.Resources>
    <!-- This style is used to set the margins for all paragraphs in the FlowDocument to 0. -->
    <Style TargetType="{x:Type Paragraph}">
      <Setter Property="Margin" Value="0"/>
    </Style>
  </FlowDocument.Resources>

  <Paragraph>
    Spacing between paragraphs is caused by margins set on the paragraphs.  Two adjacent margins
    will "collapse" to the larger of the two margin widths, rather than doubling up.
  </Paragraph>

  <Paragraph>
    To eliminate extra spacing between two paragraphs, just set the paragraph margins to 0.
  </Paragraph>
</FlowDocument>

我该怎么做？.
谢谢你的帮助。
