如何使用匹配整个单词替换richTextBox中字符串的所有实例? [英] How to replace all instances of a string inside a richTextBox using match whole word?

问题描述

伙计们，我想做的是仅在字符串与比较字符串完全匹配的情况下，才在richtextbox中搜索rtf文本并替换字符串的所有实例.
我尝试使用RTB.Replace方法，并且还定义了一个StringComparison对象，以帮助比较彼此跳转时的字符串.但是，例如，如果我有文本"aa aaaca"，而我正在搜索要替换为bbb的aa，那么我将拥有类似"bbb bbbaca"的内容，而不仅仅是"bbb aaaca"
有帮助吗?

Hey guys, what i want to do is search a rtf text inside a richtextbox and replace all instances of a string, only if the string exactly matches the comparison string.
I tried using the RTB.Replace method and I also defined a StringComparison object to help compare the strings when jumping from one another. But if for example I have the text "aa aaaca" and i''m searching for aa to replace with bbb then i''ll have something like "bbb bbbaca", instead of just "bbb aaaca"
Any help?
