The problem here is that you are declaring new members with the same
name on the derived type Truck and are not actually overriding them.
This distinction is important. Further, static members cannot be
overridden -- period. What you want is something like:
public class Vehicle {
public virtual string REG_TYPE { get { return ""; } }
public virtual string TAX_CAT { get { return ""; } }
}
public class Truck : Vehicle {
public override string REG_TYPE { get { return "G"; } }
public override string TAX_CAT { get { return "J4"; } }
}
No generics or obnoxious getter methods needed.
P.S. Names like REG_TYPE are in bad taste. Try something like RegistrationType.
