How to convert string to array in c# without using split function

Question

is there any way to convert a string like "abcdef“ to string array a char each without using the string.split function?

Thanks first

Answer 1

Yes.

"abcdef".ToCharArray();

Answer 2

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();
}

Answer 3

You could use linq and do:

string value = "abcdef";
string[] letters = value.Select(c => c.ToString()).ToArray();

This would get you an array of strings instead of an array of chars.

Answer 4

Bit more bulk than those above but i don't see any simple one liner for this.

List<string> results = new List<string>; 

foreach(Char c in "abcdef".ToCharArray())
{
   results.add(c.ToString());
}


results.ToArray();  <-- done

What's wrong with string.split???
