正则表达式c＃模式匹配 [英] Regex c# pattern match

问题描述

正则表达式模式（父级）:( [Az] {1，}） - （[az] {1，}）=此模式找出（例如：午夜）。



正则表达式模式（孩子）：需要知道用于查找单词（午夜）和（中午）的正则表达式模式。









我有一段话语。在那篇文章中（午夜，午夜，午夜）这些文字存在，我需要一个正则表达式来匹配这些文字。

请给我一个解决方案。

Regex pattern(parent):([A-z]{1,})-([a-z]{1,})= this pattern finds out(eg:mid-night).

Regex pattern (child): Need to Know regex pattern for finding words(midnight) and (mid night).




I am having a passage with a group of words. In that passage (mid-night,mid night,midnight)these words are present, i need an regex pattern to match these words from passage.
please provide me a solution.

推荐答案

我不确定正则表达式是否正是您在寻找的内容：它不是文本匹配过程，而是模式匹配过程。它无法区分：

I'm not sure that a regex is exactly what you are looking for here: it isn't a text matching process, it's a pattern matching process. It can't tell the difference between:

mid night

和

and

midnight tonight

它们都是一个字后跟一个空格，后跟一个字。



但是如果你想用你的第一个正则表达式找到

They are both "a word" followed by "a space", followed by "a word".

But if you want to find

word-otherword

然后搜索所有出现的任何

with your first regex and then search for all occurrences of any of

word-otherword
word otherword
wordotherword

然后每个人都需要你创建一个单独的正则表达式沿着行：

then each one will need you to create a separate regex along the lines of:

word[\s-]{0,1}otherword

并为你的每对匹配组运行原始的正则表达式结果。

and run that for each pair of match groups in your original regex results.
