以编程方式将属性添加到方法或参数 [英] Programmatically add an attribute to a method or parameter

问题描述

我可以使用 TypeDescriptor.AddAttributes 在运行时向类型添加属性.如何对方法和参数执行相同操作?(可能是 2 个单独的问题...)

I can use TypeDescriptor.AddAttributes to add an attribute to a type in runtime. How do I do the same for a method and parameter? (maybe 2 separate questions...)

推荐答案

TypeDescriptor.AddAttributes 只影响非常特定的用例；即来自 System.ComponentModel.对于反射的rest，它对额外的属性一无所知.事实上，System.ComponentModel 并不真正适用于方法或参数.

TypeDescriptor.AddAttributes only affects a very specific use-case; i.e. from within System.ComponentModel. For the rest of reflection, it knows nothing about the extra attribute. And indeed, System.ComponentModel doesn't really apply to methods or parameters.

简而言之；你不能.您需要将此信息存储在其他地方(定制)，或在编译时添加.

So in short; you can't. You will need to store this information somewhere else (bespoke), or add it at compile-time.
