Split a string using as separator all characters between two parenthesis in C#

Question

I need to split a string in this form

[delimA][delimB]\n1delimA2delimB3

for example if I have

[***][%]\n1***2%3

it should return an array of

1 2 3

How can I do this?

You should probably rephrase the question to `I want to read the delimiters from the beginning of the string and then use them to split the rest of the string`. I don't think you can do that with a single regex — Panagiotis Kanavos, Jan 28 '20 at 09:33
You don't need a regex for this, a single `String.Split` will work — Panagiotis Kanavos, Jan 28 '20 at 09:37
@Lx2pwnd can you add more testcases (i.e. expected output from input)? — aloisdg, Jan 28 '20 at 09:42
@aloisdgmovingtocodidact.com for exemple if i have `[kkk][??????]\n1kkk2??????3` it should return `1 2 3` — Lx2pwn, Jan 28 '20 at 10:26
@Lx2pwn Can you add more examples? Can you have number as delimiter? Is there always a `\n` between your delimiters and the tail? Does your tail is only made of numbers and non number-delimiters? — aloisdg, Jan 28 '20 at 12:33

You don't need a regular expression for this. String.Split can accept multiple delimiters, eg :

var line="[***][%%]";
var parts=.Split(new[]{'[',']'},StringSplitOptions.RemoveEmptyEntries);

StringSplitOptions.RemoveEmptyEntries as the name explains, will remove any empty entries after splitting
