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
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
