Split String into smaller Strings by length variable

Question

I\'d like to break apart a String by a certain length variable.
It needs to bounds check so as not explode when the last section of string is not as long as or longer th

Answer 1

Easy to understand version:

string x = "AAABBBCC";
List a = new List();
for (int i = 0; i < x.Length; i += 3)
{
    if((i + 3) < x.Length)
        a.Add(x.Substring(i, 3));
    else
        a.Add(x.Substring(i));
}

Though preferably the 3 should be a nice const.
