using System.Collections.Generic;
using System.Text;

namespace ANONYMOUSTYPES
{
  class Program
  {
  static void Main(string[] args)
  {
   
  // due to var keyword Compiler itself make classes of following objects.
   
  var student1 = new { name = "sumair", fathername = "irshad", age = 20 };
  var student2 = new { name = "andrew", fathername = "Hejisberg", age = 20 };
  var teacher = new { name = "BillGates", company = "Microsoft" };
  //now compiler will define myint as integer.
  var myint =4;
  //now compiler will define mystring as string.
  var mystring = "csharp";
  Console.WriteLine("STUDENTS:\n NAME = "+student1.name+" FATHERNAME = "+student1.fathername+"AGE ="+student1.age);
  Console.WriteLine(" NAME = "+student2.name+" FATHERNAME = "+student2.fathername+"AGE ="+student2.age);
  Console.WriteLine("\nTEACHER:\n NAME = " + teacher.name + "\n COMPANY = " + teacher.company);
  Console.WriteLine("\nSTRING = {0} \nINTEGER = {1}", mystring,myint);
  Console.ReadKey();
  }
  }
}
OutPut:

STUDENTS:

 NAME = sumair  FatherName = irshadAge= 20
 NAME = andrew FatherName = HejisbergAge= 20

TEACHER:

  NAME = BillGates

  Company = Microsoft

 STRING = csharp

INTEGER = 4
