推荐答案

如果您只想进行一些快速着色，最简单的解决方案可能是将 RTB 内容的末尾用作范围并对其应用格式.例如:

If you just want to do some quick coloring, the simplest solution may be to use the end of the RTB content as a Range and apply formatting to it. For example:

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);

如果您正在寻找更高级的解决方案，我建议您阅读 有关流文档的 Microsoft Doc，因为它为您设置文本格式提供了极大的灵活性.

If you are looking for a more advanced solution, I suggest reading this Microsoft Doc about Flow Document, as it gives you a great flexibility in formatting your text.
