C＃分割字符串，但保持拆分字符/分离器 [英] C# split string but keep split chars / separators

问题描述

我分裂由三个不同的字符的字符串，但我想输出包括我分裂的人物。有没有简单的方法来做到这一点？

I'm splitting a string by three different characters but I want the output to include the characters I split by. Is there any easy way to do this?

推荐答案

如果拆分字符均，，。和; ，我想尝试：

If the split chars were ,, ., and ;, I'd try:

string[] parts = Regex.Split(originalString, @"(?<=[.,;])")

（小于？= PATTERN）为正查找背后 PATTERN 。它应该匹配在任何地方，preceding文本适合 PATTERN 所以应该有任何字符的每一次出现后，比赛（和分裂）。

(?<=PATTERN) is positive look-behind for PATTERN. It should match at any place where the preceding text fits PATTERN so there should be a match (and a split) after each occurrence of any of the characters.
