.net 如何在现有Rtf文档中引入新的格式说明符

我试图扩展使用RTF的宏解析器的功能。 （VB.NET RichTextBox的自定义重载） 解析器为RTF创建一个标头，并逐行输入格式代码。 这只能处理单行表达式，我希望能够解析多行语句。 为此，我创建了一个在第一个解析器之后运行的函数，并重新解析多行语句

我面临的问题是，当我试图从RichTextBox（RichTextBox.Rtf）读取现有文本时，它返回先前输入的RichText的简化版本，不再包含整个标题，只包含使用过的位

然后，当我尝试用应该识别的新格式代码替换某些行时，它失败了

然后我尝试嵌套另一个标题，但这根本不起作用

这是一个RTF，没有像以前那样进行多行分析

它显示为默认的黑色文本

我可以附加新的格式说明符而不在外部存储RTF吗？旧的解析器一次只能处理片段，我的新函数需要整个文本，然后我使用RichTextBox.text。

我解决了它。您可以通过RichTextBox的SelectedRtf属性将带有新标题的其他富格文本注入现有富格文本
