XAML
<FlowDocumentReader>
<FlowDocument
Background="IndianRed"
Foreground="NavajoWhite"
>
<Paragraph>
This FlowDocument will have a background color of Indian red, with the text
colored Navajo white. Any Forground or Background settings on this paragraph
would override the top-level settings for the FlowDocument.
</Paragraph>
</FlowDocument>
</FlowDocumentReader>
下面的示例演示如何以编程方式设置 Background 属性。
C#
FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));
flowDoc.Background = Brushes.IndianRed;
flowDoc.Foreground = Brushes.NavajoWhite;
Dim flowDoc As New FlowDocument(New Paragraph(New Run("A bit of text content...")))
flowDoc.Background = Brushes.IndianRed
flowDoc.Foreground = Brushes.NavajoWhite
