Question

Is there a way to break a string into pairs without looking at indexes? e.g.
TVBMCVTVFGTVTB would be broken into a list of strings as such:

[TV,BM,CV,TV,FG,TV,TB]

Perhaps I should have worded the question to state is their a function similar to string.join, or string.split when working with strings to break them into groups.

Answer 1

If you like some esoteric solutions:

1)

string s = "TVBMCVTVFGTVTB";
var splitted = Enumerable.Range(0, s.Length)
                         .GroupBy(x => x / 2)
                         .Select(x => new string(x.Select(y => s[y]).ToArray()))
                         .ToList();

2)

string s = "ABCDEFGHIJKLMN";
var splitted = Enumerable.Range(0, (s.Length + 1) / 2)
                         .Select(i => 
                                 s[i * 2] + 
                                 ((i * 2 + 1 < s.Length) ? 
                                 s[i * 2 + 1].ToString() : 
                                 string.Empty))
                         .ToList();
