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()

First of all this is not good idea if you using some methods, that operates base class.
You can try to use obsolete argument to make users twice think to use this property.

[System.Obsolete("Do not use this property",true)]  
public override YourType YourProperty { get; set; }
