问题描述
简单测试表明RichtextBox. SelectionCharOffset 属性对应于"\ upn"属性. RTF标签. (例如\ up3 \ up0对).我需要检查另一种由RTF标签"\ super"定义的上标.和"\ nosupersub".这些是 当将文本从网页复制/粘贴到RichTextBox时，HTML上标(< sup></sup>)会转换为的标签.很遗憾， SelectionCharOffset 无法识别它们.
Simple tests show that RichtextBox.SelectionCharOffset property corresponds to "\upn" RTF tag. (e.g. \up3 \up0 pair). I need to check for another kind of superscripts that are defined by RTF tags "\super" and "\nosupersub". These are the tags that HTML superscripts (<sup> </sup>) are translated to when copying/pasting texts from web pages to RichTextBox. Unfortunately,SelectionCharOffset does not recognize them.
还有其他方法可以在RichTextBox中查找上标文本吗?
Is there any other way to find superscripted text within RichTextBox?
谢谢.
