定制与非定制属性？ [英] Custom vs. non-custom attributes?

问题描述

东西，它实现了 ICustomAttributeProvider 界面将让你得到那些通过 GetCustomAttributes 方法。据我了解，一个自定义属性基本上是一类特殊的（结局中的属性，延长属性类）所创建应用于类似的方法或使用适当的语法类（ [FooAttribute] 只是方法/类/等。在C＃中，例如之前）。但是，如果这是一个自定义属性，什么是的不的-custom属性？我曾经认为这是捆绑了.NET属性是非定制，但 GetCustomAttributes 甚至返回我的属性，如 System.ThreadStaticAttribute ，这是非常核心的.NET框架。

Something which implements the ICustomAttributeProvider interface will allow you to get custom attributes that have been applied to it via the GetCustomAttributes method. As I understand it, a custom attribute is basically a special class (ending in "Attribute" and extending the Attribute class) that is created to be applied to something like a method or class using the appropriate syntax ([FooAttribute] just before the method/class/etc. in C#, for example). But if that is a custom attribute, what is a non-custom attribute? I used to think that attributes that were bundled with .NET were non-custom, but GetCustomAttributes even returns me attributes like System.ThreadStaticAttribute, which are very core to the .NET framework.

有没有这样的事，作为一个非自定义属性，或者是自定义属性只是一种同义反复？

Is there such a thing as a non-custom attribute, or is "custom attribute" just a tautology?

推荐答案

我不知道下面有什么关联，但是如果说

I don't know if the following has any relevance, but if you say

var a = typeof(string).Attributes;

你称为标志枚举类型的值 TypeAttributes 。也许这些标志都是类型的非定制属性？

you get a value of a flags enum type called TypeAttributes. Maybe these flags are the "non-custom" attributes of the type?
