问题描述

我有以下代码可通过正则表达式拆分CamelCase:

I have this code to split CamelCase by regular expression:

Regex.Replace(input, "(?<=[a-z])([A-Z])", " $1", RegexOptions.Compiled).Trim();

但是,它不能正确拆分: ShowXYZColours

However, it doesn't split this correctly: ShowXYZColours

它产生 Show XYZColours 而不是 Show XYZ Colours

如何获得所需的结果?

推荐答案

支持Unicode的

(?=\p{Lu}\p{Ll})|(?<=\p{Ll})(?=\p{Lu})

故障:


(?=               # look-ahead: a position followed by...
  \p{Lu}\p{Ll}    #   an uppercase and a lowercase
)                 #
|                 # or
(?<=              # look-behind: a position after...
  \p{Ll}          #   an uppercase
)                 #
(?=               # look-ahead: a position followed by...
  \p{Lu}          #   a lowercase
)                 #

与正则表达式拆分功能一起使用.

Use with your regex split function.

当然,您可以将 \ p {Lu} 替换为 [AZ] ,将 \ p {Ll} 替换为[az] ,如果这是您所需要的,或者您的正则表达式引擎不了解Unicode类别.

Of course you can replace \p{Lu} with [A-Z] and \p{Ll} with [a-z] if that's what you need or your regex engine does not understand Unicode categories.
