How to define a structure in C#

CsharpProgrammingServer Side Programming

In C#, a structure is a value type data type. It helps you to make a single variable hold related data of various data types. The struct keyword is used for creating a structure.

To define a structure, you must use the struct statement. The struct statement defines a new data type, with more than one member for your program.

For example, here is the way you can define a structure −

struct Books {
   public string title;
   public string author;
   public string subject;
   public int book_id;
};

The following is an example showing how to create structure in C# −

Example

 Live Demo

using System;

struct Books {
   public string title;
   public string author;
   public string subject;
   public int book_id;
};

public class testStructure {
   public static void Main(string[] args) {
      Books Book1; /* Declare Book1 of type Book */
      Books Book2; /* Declare Book2 of type Book */

      /* book 1 specification */
      Book1.title = "Learn AngularJS";
      Book1.author = "David";
      Book1.subject = "AngularJS";
      Book1.book_id = 345;

      /* book 2 specification */
      Book2.title = "Learn Java in 7 days";
      Book2.author = "Jack";
      Book2.subject = "Java";
      Book2.book_id = 567;

      /* print Book1 info */
      Console.WriteLine( "Book 1 title : {0}", Book1.title);
      Console.WriteLine("Book 1 author : {0}", Book1.author);
      Console.WriteLine("Book 1 subject : {0}", Book1.subject);
      Console.WriteLine("Book 1 book_id :{0}", Book1.book_id);

      /* print Book2 info */
      Console.WriteLine("Book 2 title : {0}", Book2.title);
      Console.WriteLine("Book 2 author : {0}", Book2.author);
      Console.WriteLine("Book 2 subject : {0}", Book2.subject);
      Console.WriteLine("Book 2 book_id : {0}", Book2.book_id);

      Console.ReadKey();
   }
}

Output

Book 1 title : Learn AngularJS
Book 1 author : David
Book 1 subject : AngularJS
Book 1 book_id :345
Book 2 title : Learn Java in 7 days
Book 2 author : Jack
Book 2 subject : Java
Book 2 book_id : 567
