what is the best way in C# to convert string into int[]

Split string, convert ToList<int>() in one line…

i have a string that looks like this.

string s = "1,6,4,3,5,7,4";

and i want to convert this into an array of integers.

what is the best and fastest way of doing this in C#?

I don't know about fastest, but in C#4, a terse way would be: `var nums = Array.ConvertAll(s.Split(','), int.Parse);` — Ani, Feb 22 '11 at 06:00
@jleedev, technically, the dup doesn't address converting it to an *array*. But...the OP can just tack on `.ToArray()`. — Kirk Woll, Feb 22 '11 at 06:01

use split method.

int[] array = s.Split(',').Select(str => int.Parse(str)).ToArray();

Hmm, don't know if it is fastest way, however it is the simplest way :)

you can use `.Select(int.Parse)` instead of `.Select(str => int.Parse(str))` – align Sep 25 '17 at 09:52

Hope this helps :)

int[] i = Array.ConvertAll(s.Split(','), new Converter<string, int>(delegate (string str) { return int.Parse(str); } ));

This does not convert it into an array of `int`. – Kirk Woll Feb 22 '11 at 06:00
Which results in an array of strings – TurBas Feb 22 '11 at 06:01
My apologies for not reading the question properly... I'd stick to @Danil's answer. – PedroC88 Feb 22 '11 at 06:08
