how to split string using regex

Question

I'd like to split a string with using pattern like this:

it starts and ends with '\n' and contains an arbitrary number of whitespace or '\n' in between.

Edit:

This input:

string s = "aaa\n    \nbbb\n    \nccc\n   \n   \nddd"; 

should result in an array containing

aaa
bbb
ccc
ddd

Answer 1

Given your example, string.Split will be much cleaner.

var vals = s.Split('\n', StringSplitOptions.RemoveEmptyEntries);
