What about something like this:

import std.traits;
import std.stdio;

class A {
	int a,b;
	this(){}
	void fields(this T)(){
         writeln(FieldNameTuple!(T));
         foreach(Class; TransitiveBaseTypeTuple!(T)) {
             writeln(FieldNameTuple!(Class));
         }
	}
}

class B : A{
	int c;
	this(){}
}

class C : B{
	int d;
	this(){}
}
void main(){
	C c = new C();
	c.fields();
}
