Now here is a fuller implementation using C#
using System;
abstract class Command
{
protected Receiver receiver;
public Command(Receiver receiver)
{
this.receiver = receiver;
}
abstract public void Execute();
}
class ConcreteCommand : Command
{
public ConcreteCommand(Receiver receiver) : base (receiver) { }
public override void Execute()
{
receiver.Action();
}
}
class Receiver
{
public void Action()
{
Console.WriteLine("Called Receiver.Action()");
}
}
class Invoker
{
private Command command;
public void SetCommand(Command command)
{
this.command = command;
}
public void ExecuteCommand()
{
command.Execute();
}
}
public class Client
{
public static void Main(string[] args)
{
Receiver r = new Receiver();
Command c = new ConcreteCommand(r);
Invoker i = new Invoker();
i.SetCommand(c);
i.ExecuteCommand();
}
}
