我如何提取圆括号（圆括号）之间是文字？ [英] How do I extract text that lies between parentheses (round brackets)?

问题描述

我有一个字符串用户名（销售）我要提取的括号内的文字，我将如何做到这一点？

I have a string User name (sales) and I want to extract the text between the brackets, how would I do this?

我怀疑的子串，但我不知道如何阅读，直到右括号，文字的长度会有所不同。

I suspect sub-string but I can't work out how to read until the closing bracket, the length of text will vary.

推荐答案

一个非常简单的方法来做到这一点是通过使用常规的前pressions：

A very simple way to do it is by using regular expressions:

Regex.Match("User name (sales)", @"\(([^)]*)\)").Groups[1].Value

至于（很搞笑）评论的回应，这是同样的正则表达式有一些解释：

As a response to the (very funny) comment, here's the same Regex with some explanation:

\(             # Escaped parenthesis, means "starts with a '(' character"
    (          # Parentheses in a regex mean "put (capture) the stuff 
               #     in between into the Groups array" 
       [^)]    # Any character that is not a ')' character
       *       # Zero or more occurrences of the aforementioned "non ')' char"
    )          # Close the capturing group
\)             # "Ends with a ')' character"
