c＃中main函数的含义是什么 [英] what is mean by main function in c#

问题描述

你好，

我们知道所有c＃程序都以一个功能开始

Hello,
As we know that all c# program start with a Fuction

class program
{ 
public Static void Main()
{
 {
   //
 }
}

然后需要什么公共静态void Main（）



是程序可运行没有这个功能，如果是，那么为什么

then what is the need of public Static void Main()

is program is runnable without this function if yes then why

推荐答案

所有程序都需要从某处开始： static 主要方法是所有开始的地方 - 它必须是在程序开始时可以访问的某个地方 - 所以它不能是类构造函数（因为没有什么可以构造第一个类的第一个实例）所以它必须是一个静态方法。它被称为Main，因此链接器等等都知道要查找的内容！



如果它不被称为Main，则需要一个名称某种形式 - 所以.NET框架的设计者选择了一个名字并坚持下去。它可以追溯到C天，它被称为主。

All programs need to start somewhere: the static Main method is the place that it all begins - it has to be somewhere that is accessible at the start of the program - so it can''t be a class constructor (because there is nothing to construct the first instance of the first class) so it has to be a static method. It is called Main simply so that the linker and so forth all know exactly what to look for!

If it wasn''t called Main, it would need a name of some kind - so the designers of teh .NET framework picked a name and stuck with it. It harks back to "C" days, where it was called "main" instead.

Main（）和其他方法（C＃vs Java） [ ^ ]

您需要一个程序的入口点，以便运行时知道从哪里开始执行它。

请同时参考这个问题及所有解决方案：为什么main（）函数在c＃中应该是静态的？ [ ^ ]。



问候，

You need an entry point for a program so the runtime knows where to start executing it.
Please also refer to this question and all the solution: Why main() function should be static in c#?[^].
