In this article I am going to reverse string without using build infunction. Here reverse string achieved without using ToCharArray. First of allcalculating the string length after loops the calculated string length andlogic implemented.

using System.Text;

static void Main(string[] args)

        {

            try

            {

                string Str, Revstr = ""; 

                int Length;              //lenght of givenstring

                 Console.Write("Enter the string to reverse: ");

               Str = Console.ReadLine();          

                 Length = Str.Length - 1;          

                while (Length >= 0)                //loops the string length

               {

                   Revstr = Revstr + Str[Length];  //performimg reverse string usingLength of string

                   Length--;

               }

                Console.WriteLine("Reverse  String Is  {0}", Revstr);

             }

            catch(Exception ex) {

                Console.WriteLine(ex.ToString());

            }

            Console.ReadLine();
