C# Composite type and anonymous type sample code

Program: Class as composite type

using System;

namespace AboutClasses

{

    class CompositeTypesEx

    {

        public class employee

        {

            public string Name;

            public int age;

        }

        static public void Main()

        {

            //Here emp is a type of employee

            employee emp = new employee(); 

            emp.Name = "Anjani";

            emp.age = 21;

            //Passing employee types to methods

            DisplayEmployee(emp);

            Console.ReadKey();

        }

        static public void DisplayEmployee(employee e)

        {

            Console.WriteLine(e.Name);

            Console.WriteLine(e.age);

        }

    }

}

Output

Name Anjani


Age  21

Program: Anonymous type  (No Need to define class)

using System;

namespace AboutClasses

{

    class AnonymousTypesEx

    {

        static public void Main()

        {

            //Creating and initializing anonymous object

            var trainee = new

            {

                t_id = 134,

                t_name = "Saksham",

                t_course = ".NET"

            };

            //Accessing the object properties

            Console.WriteLine("Trainee ID  :{0}",trainee.t_id);

            Console.WriteLine("Name        :{0}",trainee.t_name);

            Console.WriteLine("Course      :{0}",trainee.t_course);

            //Passing anonymous types to methods

            DisplayTrainee(trainee);

            Console.ReadKey();

        }

        static public void DisplayTrainee(dynamic trainee1)

        {

            Console.WriteLine("Trainee ID  :{0}", trainee1.t_id);

            Console.WriteLine("Name        :{0}", trainee1.t_name);

            Console.WriteLine("Course      :{0}", trainee1.t_course);

        }

    }
