C#中的类和结构之间有什么区别？

一种类是从中创建对象的用户定义的蓝图或原型。基本上, 一个类将字段和方法(定义动作的成员函数)组合到一个单元中。

例子：

//C# program to illustrate the
//concept of class
using System;
  
//Class Declaration
public class Author {
  
     //Data members of class
     public string name;
     public string language;
     public int article_no;
     public int improv_no;
  
     //Method of class
     public void Details( string name, string language, int article_no, int improv_no)
     {
         this .name = name;
         this .language = language;
         this .article_no = article_no;
         this .improv_no = improv_no;
  
         Console.WriteLine( "The name of the author is :  " + name
                           + "\nThe name of language is : " + language
                           + "\nTotal number of article published  " 
                           + article_no + "\nTotal number of Improvements:"
                           + " done by author is : " + improv_no);
     }
  
     //Main Method
     public static void Main(String[] args)
     {
  
         //Creating object
         Author obj = new Author();
  
         //Calling method of class
         //using class object
         obj.Details( "Ankita" , "C#" , 80, 50);
     }
}

输出如下：

The name of the author is :  Ankita
The name of language is : C#
Total number of article published  80
Total number of Improvements: done by author is : 50

一种结构体是单个单元下不同数据类型的变量的集合。它几乎类似于一个类, 因为它们都是用户定义的数据类型, 并且都包含许多不同的数据类型。

例子：

//C# program to illustrate the
//concept of structure
using System;
  
//Defining structure
public struct Car
{
  
     //Declaring different data types
     public string Brand;
     public string Model;
     public string Color;
}
  
class GFG {
  
     //Main Method
     static void Main( string [] args)
     {
  
         //Declare c1 of type Car
         //no need to create an 
         //instance using 'new' keyword
         Car c1;
  
         //c1's data
         c1.Brand = "Bugatti" ;
         c1.Model = "Bugatti Veyron EB 16.4" ;
         c1.Color = "Gray" ;
  
         //Displaying the values
         Console.WriteLine( "Name of brand: " + c1.Brand + 
                           "\nModel name: " + c1.Model + 
                           "\nColor of car: " + c1.Color);
     }
}

输出如下：

Name of brand: Bugatti
Model name: Bugatti Veyron EB 16.4
Color of car: Gray
