正则表达式以匹配带有+（加号）符号的单词 [英] Regex to match a word with + (plus) signs

问题描述

我花了一些时间，但仍然必须解决。我需要能够匹配字符串中带有符号（例如c ++）的单词的正则表达式。

I've spent some time, but still have to solution. I need regular expression that is able to match a words with signs in it (like c++) in string.

我用过 / \ bword\b / ，对于常用单词，可以正常运行。但是，一旦我尝试 / \bC\ + \ + \b / ，它就不起作用。

I've used /\bword\b/, for "usual" words, it works OK. But as soon as I try /\bC\+\+\b/ it just does not work. It some how works wrong with a plus signs in it.

我需要一个正则表达式来检测输入字符串中是否包含c ++单词。像这样的输入

I need a regex to detect if input string contains c++ word in it. Input like,

"c++ developer"
"using c++ language" 

等。

ps。使用C＃.Net Regex.Match函数。

ps. Using C#, .Net Regex.Match function.

推荐答案

+ 是一个特殊字符，因此您需要对其进行转义

+ is a special character so you need to escape it

\bC\+\+(?!\w)

请注意，不能使用 \b ，因为 + 不是单词字符。

Note that we can't use \b because + is not a word-character.
