问题描述

如何用逗号分隔（ 用双引号（而不除去引号）以及其他可能的标点符号）（用文本框分隔字符串）标记（例如'。'';''-'）？

How can I split string (from a textbox) by commas excluding those in double quotation marks (without getting rid of the quotation marks), along with other possible punctuation marks (e.g. ' . ' ' ; ' ' - ')?

例如如果有人在文本框中输入以下内容：

E.g. If someone entered the following into the textbox:

apple, orange, "baboons, cows", rainbow, "unicorns, gummy bears"

如何将上述字符串拆分为以下字符串（例如，分为列表）？

apple

orange

"baboons, cows"

rainbow

"Unicorns, gummy bears..."

string[] lines = Regex.Split(value, @", (?=(?:""[^""]*?(?: [^""]*)*))|, (?=[^"",]+(?:,|$))");

foreach (string line in lines) {
