Split string by character and separate it with comma in C#

How can I separate string by character and separate each of them by comma?

I have for example value = '1234'; and I want to transform it to: value = '1,2,3,4'. So it should still be string (not an array of numbers).

I've tried this out:

var result = "1234";
var fResult = string.Join(",", result.Split());

But I did not have any success. I've got again result = "1234"; Where I'm making a mistake?

this demo for you:

var result = "1234";
var data = result.ToCharArray();
var fResult = string.Join(",", data);

Take string as char array then Join again with comma

var result = "1234";
var fResult = string.Join(",", result.ToCharArray());

Join your string as IEnumerable<char>

string input = "1234";  
string result = string.Join(",",input.AsEnumerable());
