How to determine if the property belongs to Base class or sub class dynamically using generics?

I have following two classes (models), one is base class and other is sub class:

public class BaseClass
{    
     public string BaseProperty{get;set;}    
}

public class ChildClass: BaseClass    
{    
     public string ChildProperty{get;set;}    
}

In application I am calling ChildClass dynamically using generics

List<string> propertyNames=new List<string>();
foreach (PropertyInfo info in typeof(T).GetProperties())
{
      propertyNames.Add(info.Name);
}

Here, in propertyNames list, I am getting property for BaseClass as well. I want only those properties which are in child class. Is this possible?

What I tried?

1. Tried excluding it as mentioned in this question
2. Tried determining whether the class is sub class or base class as mentioned here but that does not help either.
