推荐答案

同时查看问题中的表示并回复其他解决方案。我虽然与你分享这篇非常简单和精确的文章。它将非常容易地向您解释 Regex Fundamentals 。



轻松学习正则表达式（RegEx）





进一步解释你发布的正则表达式，你可以看看下面



/ \\< [ ^ \\>] * \\>/

\\匹配字符\字面上

<匹配字符<字面上

[^ \\>] *匹配下面列表中不存在的单个字符

量词：在零和无限次之间，尽可能多次，根据需要回馈[贪心]

\\匹配字符\字面上

>列表中的单个字符>字面意思（区分大小写）

\\匹配字符\字面意思

>匹配字符>字面意思

while looking at the "Indicates" in your question and the reply to other solution posted. I though of sharing this very easy and precise article with you. It will explain you the Regex Fundamentals very easily.

Further for the explanation of your posted Regex, You can have a look below

/\\<[^\\>]*\\>"/
\\ matches the character \ literally
< matches the character < literally
[^\\>]* match a single character not present in the list below
Quantifier: Between zero and unlimited times, as many times as possible, giving back as needed [greedy]
\\ matches the character \ literally
> a single character in the list > literally (case sensitive)
\\ matches the character \ literally
>" matches the characters >" literally

Hope it will help. :)

原始表格应该是：

the original form should be :

\<[^\>]*\>

额外的\只是为了c＃而逃避\。

它将匹配'<'和'>'所包含的任何内容或任何内容。

*表示出现零次或多次。

the extra \ is just to escape \ for the sake of c#.
It will match anything or nothing that is enclosed with '<' and '>'
The * means occurring zero or more times.
