反思找不到抽象类属性的私有设置者 [英] Reflection can't find private setter on property of abstract class

问题描述

当我在抽象类中拥有此属性时:

When I have this property in an abstract class:

public IList<Component> Components { get; private set; }

然后我打电话:

p.GetSetMethod(true)

p是一个指向我的属性的PropertyInfo对象，我得到null.

with p being a PropertyInfo object pointing to my property, I get null.

但是，如果我将属性设置器更改为protected，则可以通过反射看到它.为什么是这样?我似乎不记得非抽象类有这个问题...

However if I change the property setter to protected, I can see it via reflection. Why is this? I don't seem to recall having this problem with non-abstract classes...

推荐答案

我假设您正在从抽象类的派生类型的对象上调用此方法.该类上根本没有属性设置器.它仅位于您的抽象库上.这就是为什么当您将其标记为受受保护的时它可以工作的原因.获取属性设置器时，您需要使用抽象类的 Type .

I assume you are calling this on an object from a derived type of your abstract class. There isn't a property setter at all on that class. It is only located on your abstract base. This is why it works when you mark it as protected. You need use your abstract class' Type instead when getting the property setter.
