获取类型的继承树 [英] Get inheritance tree of type

问题描述

的要使用C＃的反射得到父类

我想找到获得在C＃中使用反射某种类型的继承树的简单方法。

I am trying to find an easy way of getting the inheritance tree of a certain type using reflection in C#.

让我们说，我有以下的类;

Let's say that I have the following classes;

public class A
{ }

public class B : A
{ }

public class C : B
{ }

我如何使用在类型'C'反射来决定其超类是'B'，谁又将来自'A'等等？我知道，我可以用'IsSubclassOf（）'，但是让我们假设，我不知道我要寻找的超类。

How do I use reflection upon type 'C' to determine that its superclass is 'B', who in turn comes from 'A' and so on? I know that I can use 'IsSubclassOf()', but let's assume that I don't know the superclass that I am looking for.

推荐答案

要得到一个类型的直接家长，您可以使用 Type.BaseType 财产。您可以反复拨打 BASETYPE ，直到它返回空走了一个类型的继承层次。

To get a type's immediate parent, you can use the Type.BaseType property. You can iteratively call BaseType until it returns null to walk up a type's inheritance hierarchy.

例如：

public static IEnumerable<Type> GetInheritanceHierarchy
    (this Type type)
{
    for (var current = type; current != null; current = current.BaseType)
        yield return current;
}

请注意，这不是有效的使用 System.Object的作为终点，因为不是所有的类型（例如，接口类型）继承它。

Do note that it isn't valid to use System.Object as the end-point because not all types (for example, interface types) inherit from it.
