C＃提取以％开头的单词！并结束！％

Question

如果单词以％！开头，以！％

结尾，我需要从一段文字中提取一些单词

我认为正则表达式对此有好处但不幸的是我的正则表达不是那么好......好吧它非常糟糕......好吧它不存在:(。

示例文字

You don't want no %!beef!%, boy
Know I run the streets, boy
Better follow me towards
Downtown
What you see is what you get %!girl!%
Don't ever forget girl
Ain't seen nothing yet until you're
%!Downtown!%

预期结果

beef, girl, Downtown

如何使用或不使用正则表达式在C＃中实现此目的？

Answer 1

像这样：

var reg = new Regex(@"%!(?<word>\w+)!%");
var inStr = @"You don't want no %!beef!%, boy
Know I run the streets, boy
Better follow me towards
Downtown
What you see is what you get %!girl!%
Don't ever forget girl
Ain't seen nothing yet until you're
%!Downtown!%";
var results = reg.Matches(inStr).Cast<Match>().Select(m => m.Groups["word"].Value);

这将为您提供匹配单词的列表。将它转换为以逗号分隔的字符串是我要留给你的练习..

另外，下次你应该做一些快速研究，你最终还是要学习简单的正则表达式。
