You can use the 'new' keyword but this will replace property, what you want is not possible with override.

public class BaseClass
{
    private BaseClass _Parent;
    public virtual decimal Result
    {
        get { return ((_Parent != null) ? _Parent.Result : -1); }
    }
}

public class DerivedClass : BaseClass
{
    private decimal _Result;
    public new decimal Result
    {
        get { return _Result; }
        set { _Result = value;  }
    }
}
