C# 动态类

Question

我正在谈论类似于动态的东西。 This没有回答我的问题，所以才有这个问题。我想要一个可以在运行时添加属性的类。它需要从object类型继承。

我见过从 DynamicObject 继承，但它没有说明如何在运行时添加属性。请帮我解释一下这个问题吗？

我有一堂这样的课:

public class SomeModel : DynamicObject {
       public string SomeMandatoryProperty {get; set;}
}

我想在运行时将另一个类的所有属性添加到此类。例如。

SomeModel m = new SomeModel();
m = someOtherClass;
string hi = m.otherClassProp; //Property from other class is added.
string mandatory = m.SomeMandatoryProperty; //From the mandatory property set previously.

我认为您正在寻找 ExpandoObject :

The ExpandoObject class enables you to add and delete members of its instances at run time and also to set and get values of these members. This class supports dynamic binding, which enables you to use standard syntax like sampleObject.sampleMember instead of more complex syntax like sampleObject.GetAttribute("sampleMember").

dynamic manager;

manager = new ExpandoObject();
manager.Name = "Allison Brown";
manager.Age = 42;
manager.TeamSize = 10;
