您可以在代碼中做到這一點：

 
    // Create a paragraph with two coloured runs 
    Paragraph para = new Paragraph(); 
    Run run1 = new Run("Red "); 
    run1.Foreground = Brushes.Red; 
    Run run2 = new Run("Green"); 
    run2.Foreground = Brushes.Green; 
    para.Inlines.Add(run1); 
    para.Inlines.Add(run2); 
    // Get the document 
    FlowDocument doc = richTextBox1.Document; 
    // Clear existing content 
    doc.Blocks.Clear(); 
    // Add new content 
    doc.Blocks.Add(para); 

或者在XAML：

<RichTextBox Height="160" HorizontalAlignment="Left" Margin="43,20,0,0" Name="richTextBox1" VerticalAlignment="Top" Width="258" TextChanged="richTextBox1_TextChanged"> 
     <FlowDocument xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> 
      <Paragraph> 
       <Run Foreground="Red">Red</Run> 
       <Run Foreground="Green">Green</Run> 
      </Paragraph> 
     </FlowDocument> 
    </RichTextBox>
