一个介绍性的小问题 [英] An introductary small problem

问题描述

  //  命名空间声明 
 使用系统; 
 
  //  程序启动类 
  class  InteractiveWelcome 
 {
  //   Main开始执行程序。 
  public   static   void  Main（）
 {
  //  写入控制台/获取输入 
 Console.Write（ 你叫什么名字？：）; 
 Console.Write（  Hello，{0}！，Console.ReadLine（） ）; 
 Console.WriteLine（ 欢迎使用C＃Station Tutorial！）; 
} 
} 
 

我只是想学习C＃语言我注意到了C ++的Main（）函数包含一个附加的类！所以我想知道是否有必要定义一个包装Main（）函数的类或声明它没有该类太好了！



另一件事我注意到它的Main（）函数由公共静态关键字组成，我知道公共的含义但是使用的是什么？我的意思是说我们为什么声明public，因为main（）函数应该已经可用于所有代码{global scope}。我无法从任何电子书中得到任何成功的答案，所以任何人都可以帮助我尝试理解它们！

解决方案

使用访问修饰符 public for entry-point method Main 只不过是你的幻想。你拥有它只是因为你已经这么写了。它不一定在那里。



请参阅： http://en.wikipedia.org/wiki/Main_function#C.23 [ ^ ]。

< blockquote> C＃是面向对象的语言而不是功能语言，因此 Main 方法封装在类结构中。



public static Main（）是运行时知道从哪里开始程序的约定。

// Namespace Declaration
using System;

// Program start class
class InteractiveWelcome
{
    // Main begins program execution.
    public static void Main()
    {
        // Write to console/get input
        Console.Write("What is your name?: ");
        Console.Write("Hello, {0}! ", Console.ReadLine());
        Console.WriteLine("Welcome to the C# Station Tutorial!");
    }
}

I was just trying to learn C# language an i noticed that unlike C++ its Main() function includes an additional class wrapped around it! So i am wondering is it necessary to define an class wrapping Main() func or declaring it without that class will too be fine!

Another thing i noticed that its Main() func consists of public static keyword , i know the meaning of public but whats the use? i mean to say that why are we declaring public as the main() function should be already available to all the code{ global scope}. I couldnt any succesful answer from any E-book, so anybody could help me try to understand them!!

解决方案

The use of the access modifier public for the entry-point method Main is nothing but your fantasy. You have it just because you've written so. It doesn't have to be there.

Please see: http://en.wikipedia.org/wiki/Main_function#C.23[^].

—SA

C# is an object orientated language not a functional one hence the Main method is encapsulated within a class structure.

public static Main() is a convention for the runtime to know where to start the program from.
