  Example8_8.cs illustrates interface member hiding

using System;

// define the IDrivable interface
public interface IDrivable
  void TurnLeft();

// define the ISteerable interface (derived from IDrivable)
public interface ISteerable : IDrivable
  new void TurnLeft();  // hides TurnLeft() in IDrivable

// Car class implements the IMovable interface
class Car : ISteerable

  // explicitly implement the TurnLeft() method of the ISteerable interface
  void ISteerable.TurnLeft()
    Console.WriteLine("ISteerable implementation of TurnLeft()");

  // implement the TurnLeft() method of the IDrivable interface
  public void TurnLeft()
    Console.WriteLine("IDrivable implementation of TurnLeft()");


public class Example8_8

  public static void Main()

    // create a Car object
    Car myCar = new Car();

    // call myCar.TurnLeft()
    Console.WriteLine("Calling myCar.TurnLeft()");

    // cast myCar to ISteerable
    ISteerable mySteerable = myCar as ISteerable;
    Console.WriteLine("Calling mySteerable.TurnLeft()");

    // cast myCar to IDrivable
    IDrivable myDrivable = myCar as IDrivable;
    Console.WriteLine("Calling myDrivable.TurnLeft()");
