是否有可能在运行时添加的属性或在运行时改变属性的值？

Is it possible to add attributes at runtime or to change the value of an attribute at runtime?

推荐答案

属性是静态的元数据。组件，模块，类型，成员，参数和返回值是在C＃中没有第一类对象（如的System.Type类是一类仅仅是一个反映再presentation）。你可以得到一种类型的属性的一个实例，并改变它的性质，如果它们是可写的，但是，这将不影响属性，因为它是应用到该类型

Attributes are static metadata. Assemblies, modules, types, members, parameters, and return values aren't first-class objects in C# (e.g., the System.Type class is merely a reflected representation of a type). You can get an instance of an attribute for a type and change the properties if they're writable but that won't affect the attribute as it is applied to the type.
