如何正确地将字符串转换为单词和标点符号列表？

Question

I have string: IDLIST, ID NAME; . And need to turn it into list: {"IDLIST", ",", "ID", "NAME", ";"} .

It's obvious how to slice string by free spaces, but what to do with punctuation marks?

Words can be any set of letters. Punctuation marks also can be any.

Answer 1

You could use Regex.Split function like below,

string value = "IDLIST, ID NAME;";
string[] lines = Regex.Split(value, @"\s+|(?!^)(?=\p{P})|(?<=\p{P})(?!$)");
foreach (string line in lines) {
Console.WriteLine(line);

OR

You could match all the punctuations or the alphabets and then append the matched strings to a list.

@"\p{P}|\p{L}+"

DEMO

\\p{P} matches any kind of punctuation marks and p{L} matches any kind of letter from any language.
