If i have string like that:
string s = "xzy...";
how to convert it to array like that:
string[] ss = {"x", "z", "y", ...}
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())
s.ToCharArray() but didn't know how to convert it to string array just using just one line of code.
