Question

Is there any way to convert a string ("abcdef") to an array of string containing its character (["a","b","c","d","e","f"]) without using the String.Split function?

Answer 1

So you want an array of string, one char each:

string s = "abcdef";
string[] a = s.Select(c => c.ToString()).ToArray();

This works because string implements IEnumerable<char>. So Select(c => c.ToString()) projects each char in the string to a string representing that char and ToArray enumerates the projection and converts the result to an array of string.

If you’re using an older version of C#:

string s = "abcdef";
string[] a = new string[s.Length];
for(int i = 0; i < s.Length; i++) {
    a[i] = s[i].ToString();
}
