Answer 1

您可以在C＃中使用Flow文檔 ，使用FlowDocument.FontWeight

<FlowDocumentReader>
  <FlowDocument
    FontFamily="Century Gothic"
    FontSize="12"
    FontStretch="UltraExpanded"
    FontStyle="Italic"
    FontWeight="UltraBold"
  >
    <Paragraph>
      Any font settings on this paragraph would override the font settings
      for the FlowDocument.
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));
// Set the desired column gap to 10 device independend pixels.
flowDoc.FontFamily = new FontFamily("Century Gothic");
flowDoc.FontSize = 12.0;
flowDoc.FontStretch = FontStretches.UltraExpanded;
flowDoc.FontStyle = FontStyles.Italic;
flowDoc.FontWeight = FontWeights.UltraBold;

另一種方法是使用運行標簽，如@Gaurang建議：

public SectionExample()
{

    // Create three paragraphs
    Paragraph myParagraph1 = new Paragraph(new Run("Paragraph 1"));
    Paragraph myParagraph2 = new Paragraph(new Run("Paragraph 2"));
    Paragraph myParagraph3 = new Paragraph(new Run("Paragraph 3"));

    // Create a Section and add the three paragraphs to it.
    Section mySection = new Section();
    mySection.Background = Brushes.Red;

    mySection.Blocks.Add(myParagraph1);
    mySection.Blocks.Add(myParagraph2);
    mySection.Blocks.Add(myParagraph3);

    // Create a FlowDocument and add the section to it.
    FlowDocument myFlowDocument = new FlowDocument();
    myFlowDocument.Blocks.Add(mySection);

    this.Content = myFlowDocument;
}
