答

如果你只想做一些快速着色，使用RTB内容为范围的结束和格式应用于它也许是最简单的解决方案，例如

If you just want to do some quick coloring , using the end of the RTB content as a Range and apply formatting to it is maybe the simplest solution, e.g.

  TextRange rangeOfText1 = new TextRange(richTextBox.Document.ContentEnd, richTextBox.Document.ContentEnd);
  rangeOfText1.Text = "Text1 ";
  rangeOfText1.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Blue);
  rangeOfText1.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);

  TextRange rangeOfWord = new TextRange(richTextBox.Document.ContentEnd, richTextBox.Document.ContentEnd);
  rangeOfWord.Text = "word ";
  rangeOfWord.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Red);
  rangeOfWord.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Regular);

  TextRange rangeOfText2 = new TextRange(richTextBox.Document.ContentEnd, richTextBox.Document.ContentEnd);
  rangeOfText2.Text = "Text2 ";
  rangeOfText2.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Blue);
  rangeOfText2.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);

如果你正在寻找一种更先进的解决方案，我建议您阅读有关的FlowDocument 一>，因为这让你在格式化文本极大的灵活性。

If you are looking for a more advanced solution, I suggest reading the MSDN page about the FlowDocument, as this gives you a great flexibility in formatting your text.
