object - Are you missing a using directive or an assembly reference in c# on creating Obect of different class -

i new c# (had c++ background before).

i have class "myclass" creates object of class "symbols" in same namespace. create object of class "symbols" in order define function "add_symbol()" called "myclass".

in c++ quiet easy:

void nameoftheclass::nameofthefunction() { } 

but don't know how in c#. tried code below , got following error(see @ last).

using system; using system.io; using system.collections.generic; using system.linq; using system.text;  namespace shekhar_final {      public class symbols      {         public void add_symbol(byte processingvalue) //called myclass         {             console.writeline(processingvalue);         }      }        public class myclass     {         public static void main(string[] args)         {             symbols objsym =new objsym(); //here error             using (var stream = new binaryreader(system.io.file.openread(args[0])))             {                 while (stream.basestream.position < stream.basestream.length)                 {                     byte processingvalue = stream.readbyte();                     objsym.add_symbol(processingvalue); //this function called defined in symbol class                 }             }         }     }   } 

the error (i have pointed line causing error in code) :

error cs0246: type or namespace name `objsym' not found. missing using directive or assembly reference? 

please me in removing error , guidance appreciated because new c#, thanks

instead of

symbols objsym = new objsym();

you should initialize class:

symbols objsym = new symbols();.

right trying initialize variable , not class.
