C# 正则表达式在模式中提取分隔文本

C# 正则表达式在模式中提取分隔文本,c#,regex,C#,Regex,我试图解析一种带有引号或尖括号中的关键字的标记 “之间的单词是静态关键字,而之间的单词是动态关键字 样本: * Say "hello" to "world" * Say <something> to <somebody> * I can also be a plain statement 更新2 有一些人建议分步骤执行此操作,即在第一步中获取所有有效行,然后在每一行中查找关键字。我希望将此作为我的最后一个选项,上下文是此代码的使用者需要知道关键字及其在整个字符串中的位置

我试图解析一种带有引号或尖括号中的关键字的标记

之间的单词是静态关键字,而
之间的单词是动态关键字

样本:

* Say "hello" to "world"
* Say <something> to <somebody>
* I can also be a plain statement

有一些人建议分步骤执行此操作,即在第一步中获取所有有效行,然后在每一行中查找关键字。我希望将此作为我的最后一个选项,上下文是此代码的使用者需要知道关键字及其在整个字符串中的位置。因此,维护偏移量是我在spl中需要的开销单击父字符串。

下面的表达式将提取所有关键字。请尝试

看看如何通过正则表达式将行提取到字符串中,然后将其拆分?
string[]result=regexString.split(“”);
。您的结果将是每个偶数索引(2,4,6,8..)。@C4ud3x-Ah但有一个问题-如果拆分行,我需要跟踪偏移量(即行号)对于这个比特的消费者,我正试图避免它。是的,这可能是一个不好的方法。检查Coder Hawk的解决方案。它只抓取关键字。正则表达式I
