在C# 中,結構是值型別資料結構。它使得一個單一變數可以儲存各種資料類型的相關資料。struct關鍵字用於建立結構。
結構是用來代表一個記錄。假設您想追蹤圖書館中書的動態。您可能想追蹤每本書的以下屬性:
Title
Author
Subject
Book ID
定義結構
為了定義一個結構,您必須使用struct 語句。struct 語句為程式定義了一個帶有多個成員的新的資料類型。
struct Books
{
public string title;
public string author;
public string subject;
public int book_id;
};
複製代碼
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; /* 宣告Book1,類型為Book */
Books Book2; /* 宣告Book2,類型為Book */
/* 書 1 詳述*/
Book1.title = "C Programming";
Book1.author = "Nuha Ali";
Book1.subject = "C Programming Tutorial";
Book1.book_id = 6495407;
/* 書 2 詳述*/
Book2.title = "Telecom Billing";
Book2.author = "Zara Ali";
Book2.subject = "Telecom Billing Tutorial";
Book2.book_id = 6495700;
/* 列印Book1 訊息*/
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);
/* 列印Book2 訊息*/
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();
}
}
