问题描述

什么是两个关键词阴影和的Overrides ？他们做了什么和什么背景下是一个或另一个preferable？

What is the significance of the two keywords Shadows and Overrides? What they do and for which context is one or the other preferable?

推荐答案

我不会考虑阴影，真正成为一个面向对象的概念。覆盖表明您提供新的或额外的功能，它被应用于一个父类中定义的方法/属性等。阴影真的招数编译以为父方法/属性等根本不存在。

I wouldn't consider Shadows to really be an OOP concept. Overrides indicates that you are providing new or additional functionality for a method/property etc that was declared in an ancestor class. Shadows really tricks the compiler into thinking that the parent method/property etc does not even exist.

我有没有用阴影。坚持覆盖。这些类型的VB已经为多年来始终最终导致你解忧在某些时候有用的小特色。

I have no use for Shadows. Stick to Overrides. These types of helpful little "features" that VB has provided for years always end up causing you grief at some point.
