类装饰器和继承类之间的区别 [英] Difference between class decorator and Inheriting class

问题描述

我正在学习NUnit，发现我们在每个测试函数之前使用 [TestMethod] 之类的类修饰符。

I was learning about NUnit and found we use class decorators like [TestMethod] before every test function.

然后我在此链接中了解了装饰器。根据这个答案

Then i learnt about decorators at this link. According to this answer

在C＃中添加装饰器时，就像在 class / method 中添加属性一样。

我只是想问一下我是否要使用整个类中使用的属性（不是在谈论一种方法）那我为什么不选择继承于类装饰器

I just want to ask if I want to use property to be used in whole class (not talking about one method) then why don't I choose inheritance over class decorator

有什么区别...

推荐答案

请小心，因为您提供的链接使用装饰器一词来指2个完全不同的概念。该链接中的问题是在问这个问题：

Be careful because the link you provided is using the word Decorator to refer to 2 entirely different concepts. The question in that link is asking this question:

装饰类或参数是什么意思？

What does it mean to Decorate a class or parameter?

一些答案​​，请正确回答问题，特别是此和此。两者都在谈论装饰器模式。

Some answers, answer the question correctly specifically this and this. Both of these are talking about the Decorator Pattern.

但是，此答案是在谈论完全不同的东西。尽管 decorator 可以用来表示属性（在C＃中带有方括号），但是SO线程正在使用它来表示 Decorator Pattern >和属性。

However, this answer is talking about something entirely different. Although decorator can be used to mean Attributes (the ones with square brackets in C#) but that SO thread is using it to mean both the Decorator Pattern and Attributes.

属性

属性在此处中进行解释。
