You're looking for ToCharArray().

This returns an array of chars.
If you really need an array of strings, you can write

Array.ConvertAll(s.ToCharArray(), c => c.ToString())

If you'd like to convert it to an array of characters you can use

s.ToCharArray();

But note that it already implements IEnumerable<char> and has an indexer by position. If you really need strings

s.Select(c => c.ToString()).ToArray()
