如何在C#中定义结构
在C#中，结构是值类型数据类型。它可以帮助您使单个变量保存各种数据类型的相关数据。struct关键字用于创建结构。
要定义结构，必须使用struct语句。struct语句定义了一种新的数据类型，该程序具有多个成员。
例如，这是您定义结构的方式-
struct Books {
public string title;
public string author;
public string subject;
public int book_id;
};以下是显示如何在C#中创建结构的示例-
示例
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();
}
}输出结果
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
