Access to properties of abstract class with reflection

I have an abstract class — let's nam开发者_StackOverflowe it Base. This class contains some properties. Moreover, I have another class, inherited from class Base — let's name it Child. Child is not abstract.

I want to access the properties from class Base with Reflection, and only those properties declared in Base.

The following code is of course not possible, because I can't create an instance of an abstract class

Base base = new Base();
Type type = base.GetType();
PropertyInfo[] propInfos =
    type.GetProperties(
        BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly
    );

The following code is possible, but I get all properties, those defined in Base as well as those defined in Child.

Child child = new Child();
Type type = child.GetType();
PropertyInfo[] propInfos =
    type.GetProperties(BindingFlags.Instance | BindingFlags.Public);

How can I get all properties of class Base via Reflection?

Try this:

Type type = typeof(A);

PropertyInfo[] propInfos 
    = type.GetProperties(BindingFlags.Instance 
        | BindingFlags.Public 
        | BindingFlags.DeclaredOnly);

Invoking GetType() on an object is only one of the ways of getting a Type object. Another, which works even for abstract classes, is typeof(). Using the BindingFlags.DeclaredOnly option with typeof(A).GetProperties should do the trick.
