How to divide string to array of chars?

Question

For example:
string userInput = Console.ReadLine();
//let userInput be "abcde"
char [] example = func(userInput);
Console.WriteLine(example[3]);
// should output d

Answer 1

thanks both are exactly what I'm looking for

Answer 2

char[] example = userInput.ToCharArray();

I think that's what you need.

Answer 3

A string is already an array of Chars:

string hey = Console.ReadLine();
Console.WriteLine(hey[2]);

if I type "What's up", the output would "a".
Is this what you was looking for?
