struct in asp net c#

A struct type is a value type that contain the value in the stack. A struct is a simple user-defined type.

Struts support access modifiers, constructors, constants, fields, methods, properties, indexers, operators, events etc.

1. Structure cannot be inherited and we can say they are sealed. 
2. Structure is implicitly inherit from System.ValueType. 
3. The default constructor of a structure initializes each field to a default value. 
4. You cannot replace the default constructor of a structure. 
5. You cannot define destructor in Structure. 
6. Structs can be inherited from an interface.

Define a struct

public struct Student

{

    public int Id;

    public int Name;

    public double Age;

}

Example of Struct

 namespace StructDisplay

{

    public class ProgramStruct

    {

        public struct Student

        {

            public int Id;

            public string Name;

            public double Age;

            public Student(int Id, string Name, double Age)

            {

                this.Id = Id;

                this.Name = Name;

                this.Age = Age;

            }

            public void DisplayValues()

        {

            Console.WriteLine("Id: " + this.Id.ToString());

            Console.WriteLine("Name : " + this.Name.ToString());

            Console.WriteLine("Age : " + this.Age.ToString());I

        }

        }

        static void Main(string[] args)

        {

            Student stuobjl = new Student(786, "Anil Singh", 28);

            stuobjl.DisplayValues();

            Console.ReadLine();

        }

    }

}

The Output as given below

Id: 786

Name: Anil Singh

Age: 28

How Struct can be inherited from an interface?

Example for implementation to struct can be inherited from an interface

namespace StructUsinglnterface

{

    public class Program

    {

        public interface Ii

        {

            void DisplayValues();

            public struct Student : Ii

            {

                int Id;

                string Name;

                int Age;

                public Student(int Id, string Name, int Age)

                {

                    this.Id = Id;

                    this.Name = Name;

                    this.Age = Age;

                }

                public void DisplayValues()

                {

                    Console.WriteLine("Id: " + this.Id.ToString());

                    Console.WriteLine("Name : " + this.Name.ToString());

                    Console.WriteLine("Age : " + this.Age.ToString());

                    Console.WriteLine("Age : " + this.Age.ToString());

                }

            }

            static void Main(string[] args)

            {

                Student student = new Student(786, "Anil Singh", 28);

                student.DisplayValues();

                student.DisplayValues();

                Console.ReadLine();

            }

        }

    }

}

The Output as given below.

Id: 786

Name: Anil Singh

Age: 28
