Hi, Try this below code for sample. int count,cnt; private void test1_string() { string x = "ABAB"; string secondStr = "CDCD"; string thirdStr = "MMKK"; string[] names = { x, secondStr, thirdStr }; foreach (string value in names) { List a = new List (); for (int i = 0; i { if ((i + 2) a.Add(value.Substring(i, 2)); else a.Add(value.Substring(i)); } string st1 = a[0].ToString(); string st2 = a[1].ToString(); if (st1 == st2) { count = count + 1; } else { cnt = cnt + 1; } } Response.Write("Is " + count + " Strings has the same pattern letters:" + count); Response.Write(" "); Response.Write("Is " + cnt + " Strings has the same pattern letters:" + cnt); }

you can implement a custom method to check if they had the same pattern letters, this is a sample when i transform string to number after that i check if the numbers are equals or not : class Program { static void Main( string [] args) { string firstStr = "ABAB" ; string secondStr = "CDCD" ; string thirdStr = "MMKK" ; Console.WriteLine( "Is two Strings has the same pattern letters :" + (GetTransform(secondStr) == GetTransform(firstStr))); Console.WriteLine( "Is two Strings has the same pattern letters :" + (GetTransform(secondStr) == GetTransform(thirdStr))); } static int GetTransform( string str) { string result = string .Empty; Dictionary char , int > dic = new Dictionary char , int >(); for ( int i = 0; i { if (!dic.ContainsKey(str[i])) { dic.Add(str[i], i + 1); result += (i + 1); } else { result += dic[str[i]]; } } return int .Parse(result); } }
