Interface Magic (at least to me)

Didn't know that interface could intercept the method of the base class even that base class is not implementing the interface

using System;
                    
public class Program
{
    public static void Main()
    {
        IRobot r = new Robot();

        r.SaySomething();
    }
}


public class Machine
{
    public void SaySomething()
    {
        Console.WriteLine("Hello");
    }
}

public interface IRobot
{
    void SaySomething();
}


public class Robot : Machine, IRobot
{
// and we don't have to implement IRobot here    
}

Output:

Hello

I still have to find a use for that code found somewhere



Happy Coding!
