Although it probably won't execute as quickly as the conventional approach here's a concise way to do the same thing using regular expressions: using System; using System.Text.RegularExpressions; class Test { static void Main() { string s = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789; s = Regex.Replace(s .{30} $0
); s = s.TrimEnd('' '
'); // remove a trailing 
 if there is one Console.WriteLine(s); Console.ReadKey(); } }

This should do it: using System; class Test { static void Main() { string s = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789; int len = s.Length / 30; int rem = s.Length % 30; if (rem > 0) len++; string[] lines = new string[len]; int j = 0; for(int i = 0; i { if (i + 30 { lines[j] = s.Substring(i 30); j++; } else { lines[j] = s.Substring(i); } } s = String.Join(
 lines); Console.WriteLine(s); Console.ReadKey(); } }
