Splitting string into pairs with c#

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]

Oh come on, just use indexes like this:

public static class StringExtensions {
    public static IEnumerable TakeEvery(this string s, int count) {
        int index = 0;
        while(index < s.Length) {
            if(s.Length - index >= count) {
                yield return s.Substring(index, count);
            }
            else {
                yield return s.Substring(index, s.Length - index);
            }
            index += count;
        }
    }
}

I have added no guard clauses.

Usage:

var items = "TVBMCVTVFGTVTB".TakeEvery(2);
foreach(var item in items) {
    Console.WriteLine(item);
}
