   Response.write(b.x); 

  Response.write(b.y);

  A a =b;  // downcasting

  Response.write(a.x);

  Response.write(a.y);

  }

}

public class A

{

  public int x=10;

  public string y="hello";

}

public class B:A   // inheritance

 {

  new public int x=20;         // ussing new keyword

  new public string y="palle";   //ussing new keyword

 }

}
