If hi karthik can only appear at most once in the string then try this: using System; using System.Text; class Test { static void Main() { string s = aaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbhi karthikccccccccccccccccccccdd; int index = s.IndexOf(hi karthik); if (index == -1) { s = Splitter(s); } else { string temp = Splitter(s.Substring(0 index)); temp += 
hi karthik; if (s.Length >= index + 10) { string temp2 = Splitter(s.Substring(index + 10)); temp += 
 + temp2; } s = temp; } Console.WriteLine(s); Console.ReadKey(); } static string Splitter(string s) { int numLines = s.Length/20; int remainder = s.Length % 20; if (remainder > 0) numLines++; StringBuilder sb = new StringBuilder(); string line = null; for(int i = 0; i { if (i { line = s.Substring(i * 20 20); sb.Append(line); sb.Append(
); } else { line = s.Substring(i * 20); sb.Append(line); } } return sb.ToString(); } }
