清洁代码哪个版本正确？

Question

当有唯一的代码是一个类你会如何编写其添加公众默认类，像这样

namespace HW2_2_Spaceship 
{ 
    public class Spaceship //added public to the default class 
    { 
     static void Main(string[] args) 
     { 
     } 

或

namespace HW2_1_Book 
{ 
    class Book 
    { 
     static void Main(string[] args) 
     { 

     } 
     public class Book // added a new class with in the default class 
     { 

Answer 1

一般情况下，每个类都应该有自己的文件。

Main应在Program.cs中

有usecases这里可以用内部类，见​​Using Inner classes in C#。

Answer 2

//Program.cs, if u use visual studio then ensure you add 
// the public access modifier yourself 

namespace HW2_2_Spaceship 
{ 
    public class Program 
    { 
     public static void Main(string[] args) 
     { 
     //Do something here 
     } 
    } 
} 

//Book.cs, add the public modifier to the class 
namespace HW2_2_Spaceship 
{ 
    public class Book 
    { 
    //add method and properties here 
    } 
}
