How can I hide a base class public property in the derived class

Question

I want to hide the base public property(a data member) in my derived class:

class Program
{
    static void Main(string[] args)
    {
        b obj = new b()

What you actually need are interfaces:

    public interface ProvidesItem1
    {
        int item1 { get; set; }
    }

    public interface ProvidesItem2
    {
        int item2 { get; set; }
    }

    class a : ProvidesItem1, ProvidesItem2
    {
        public int item1 { get; set; }
        public int item2 { get; set; }
    }

    class b : ProvidesItem1
    {
        public int item1 { get; set; }
    }

Then just pass the interfaces around. If the classes should use a common implementation, put that in a third class and let them derive from that class aswell as implement their respective interface.
