My questions are related to my previous post at http://p2p.wrox.com/topic.asp?TOPIC_ID=50274

    class Parent : IDisposable
    {
        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }
        protected virtual void Dispose(Boolean disposing)
        {
            if (disposing)
            {
                Console.WriteLine("parent managed");
            }
            Console.WriteLine("parent unmanaged");
        }
        ~Parent()
        {
            Dispose(false);
            Console.WriteLine("parent dtor");
        }

    }
    class Child : Parent
    {
        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                Console.WriteLine("child managed");
            }
            Console.WriteLine("child unmanaged");
            base.Dispose(disposing);
        }
        ~Child()
        {
            Dispose(false);
            Console.WriteLine("child dtor");
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            Child c = new Child();
            c.Dispose();
            Console.WriteLine("end main");
        }
    }

In my understanding, when I call c.Dispose(), GC.SuppressFinalize(this) will suppress Child.Finalizer only. However, the output differs from what I hope -- both Parent.Finalizer and Child.Finalizer are suppressed. Please help me to digest it.

Note: Since Parent has implemented its Finalizer, Child.Finalizer must not be implemented to avoid twice disposing when we forget to call Child.Dispose(). I create Child.Finalizer here just to support this problem.
