C# 控制台如何工作？

Question

这是一个非常基本的问题，

但是怎么样，比如

Console.Write("test");

工作？

Console 是一个类，而不是一个对象。

我以控制台为例，因为它很常用，但我见过很多使用 Class.method() 而不是 object.method() 的例子。

该方法称为静态方法:Static Classes and Static Class Members (C# Programming Guide) .

您不需要实例来调用静态类成员:

A non-static class can contain static methods, fields, properties, or events. The static member is callable on a class even when no instance of the class has been created. The static member is always accessed by the class name, not the instance name. Only one copy of a static member exists, regardless of how many instances of the class are created. Static methods and properties cannot access non-static fields and events in their containing type, and they cannot access an instance variable of any object unless it is explicitly passed in a method parameter.
