Question

I hava a string like this:

var id = "01020304";

Is there a simple way I can split this into four variables called pr, pa, fo, it Each variable needs to have the two characters of the string. Looking for an elegant solution if it exists.

Answer 1

Since you have four distinct variables, you can’t get much more elegant than using Substring:

var pr = id.Substring(0, 2);
var pa = id.Substring(2, 2);
var fo = id.Substring(4, 2);
var it = id.Substring(6);

Were you looking for an array of four 2-character substrings, you could get fancier:

var parts = new string[4];
for (int i = 0 ; i != parts.Length ; i ++) {
    parts[i] = id.Substring(2*i, 2);
}

EDIT: The same can be done with a LINQ expression:

var parts = Enumerable
    .Range(0, id.Length/2)
    .Select(i => x.Substring(2*i, 2))
    .ToArray();
