return type of derived class

[svidgen]

Is it possible to have a base-class method designate a return-value of "the" derived class, and then create and return an instance of (or "relative to") whichever derived class it's called from?

abstract class Base {
  public static List<*DerivedClass*> BuildFromList(List<String> in_s) {
    List<*DerivedClass*> rv = new List<*DerivedClass*>();
    foreach (String s in in_s) {
      rv.Add(new *DerivedClass*(s));
    }
  }
  return rv;
}

Can this be done, or am I better off just using generics anyway?

Thanks.
