Two other possible interpretations of your question: 1. if (str.Length >= 2) { // do something } 2. if (str.Contains(char1.ToString()) && str.Contains(char2.ToString())) { // do something }

This looks for each 2-character-gram of s1 and looks for it in s2. string s1 = Chrx; string s2 = Christopher; IsMatchOn2Characters(s1 s2); static bool IsMatchOn2Characters(string a string b) { string s1 = a.ToLowerInvariant(); string s2 = b.ToLowerInvariant(); for (int i = 0; i { if (s2.IndexOf(s1.Substring(i2)) >= 0) return true; // match } return false; // no match }
