Hi,   You can go with built in functionality in string content. Please go with the following example. In this case don't put "-" between the drl and driveLetter because string.Length  functionality will calculate that one also.    Code :   using  System;                          public   class  Program   {        public   static   void  Main()       {            string  driveLetter = "a" ;             string  drl =  "Hello" ;           drl =  drl + driveLetter;            Console.WriteLine(drl.Length);       }   }   //RajeeshMenoth        Demo :   https://dotnetfiddle.net/tepilK
