Examples on Value Types and Reference Types

3.Program1:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Csharp

{

    /// <summary>

    /// 1.Value Types  Struct

    /// </summary>

    class ValuetypeStruct

    {

        static void Main(string[] args)

        {

            Person p = new Person("Tony", "Allen", 32);

            Console.Write(p.ToString());

            Console.ReadLine();

        }

        struct Person

        {

            public string firstName;

            public string lastName;

            public int age;

            public Person(string _firstName, string _lastName, int_age)

            {

                firstName = _firstName;

                lastName = _lastName;

                age = _age;

            }

            public override string ToString()

            {

                return firstName + lastName + age;

            }

        }

    }

}

4.Program 2:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Csharp

{

    /// <summary>

    /// Extending program1 to make use of enum

    /// </summary>

    class Enum

    {

        static void Main(string[] args)

        {

            Person p = new Person("Tony", "Allen", 32, Person.Genders.Male);

            Console.Write(p.ToString());

            Console.ReadLine();

        }

        struct Person

        {

            public string firstName;

            public string lastName;

            public int age;

            public Genders gender;

            public Person(string _firstName, string _lastName, int _age, Genders _gender)

            {

                firstName = _firstName;

                lastName = _lastName;

                age = _age;

                gender = _gender;

            }

            public override string ToString()

            {

                return firstName + " " + lastName + " ," + gender + ", age " + age;

            }

            public enum Genders : int { Male, Female };

        }

    }

}

5.Program 3:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Csharp

{

    /// <summary>

    /// Example of Reference Type

    /// </summary>

    class Referencetypeclass

    {

        static void Main(string[] args)

        {

            Person p = new Person("Tony", "Allen", 32, Person.Genders.Male);

            Console.Write(p.ToString());

            Console.ReadLine();

        }

        class Person

        {

            public string firstName;

            public string lastName;

            public int age;

            public Genders gender;

            public Person(string _firstName, string _lastName, int _age, Genders _gender)

            {

                firstName = _firstName;

                lastName = _lastName;

                age = _age;

                gender = _gender;

            }

            public override string ToString()

            {

                return firstName + " " + lastName + " ," + gender + ", age " + age;

            }

            public enum Genders : int { Male, Female };

        }

    }
