获取子类的属性 [英] Get properties of sub class

问题描述

我有这样的课

I have class like this

public class Person
{
   public string Id{get;set;}
   public string Name{get;set;}
}

我正在将此Person类继承为Contact类

I'm inheriting this Person class to the Contact class

public class Contact : Person
{
  public string Address{get;set;}
}

我正试图从另一个类中获取像这样的联系人类的属性

From another class I'm trying to get the properties of the contact class like this

propertydescriptorcollectionpc = TypeDescriptor.GetProperties(typeof(Contact));

但是，这仅给出了超类的属性.如何将子类的属性获取到propertydescription集合.

But this gives only the super class's properties only. How can I get the sub class's properties to a propertydescription collection.

推荐答案

使用 Type.GetProperties 代替，它也可以选择返回基本类型的属性. TypeDescriptor设计用于与类型本身之外的组件一起使用 会影响结果.

Use Type.GetProperties instead which can optionally return properties of base types as well.  TypeDescriptor is designed more for use with components where things outside the type itself can impact the results.
