为什么不构造继承？ [英] Why are constructors not inherited?

问题描述

我猜有一些非常基本的关于C＃继承，我不明白。会有人请赐教？

I'm guessing there's something really basic about C# inheritance that I don't understand. Would someone please enlighten me?

推荐答案

有时，子类时，要限制创建类的实例所需的条件。

Sometimes, when subclassing, you want to restrict the conditions required to create an instance of the class.

让我给你举个例子。如果确实类继承其超类的构造函数，所有的类就必须从对象参数构造函数。显然，这是不正确的。

Let me give you an example. If classes did inherit their superclass constructors, all classes would have the parameterless constructor from Object. Obviously that's not correct.
