如何提取子字符串 [英] How to extract the sub string

问题描述

我想提取两个字符之间的子字符串

I want to extrct the substring between two char

推荐答案

如果您事先知道两个字符的位置，则可以使用(足够奇怪) String.Substring [ String.IndexOf [ ^ ]方法).
或者，您可以使用正则表达式类 [

If you know in advance the positions of the two chars then you may use (strangely enough) the String.Substring[^].
On the other hand, if you don''t know such positions then you need to first locate them (via, for instance the String.IndexOf[^] method).
Alternatively, you may use the Regex Class[^].

有几种方法可以实现.

您可以使用正则表达式提取该子字符串，也可以只使用Substring方法.
