                        string message = "Hello World! " + i.ToString();
                        var body = Encoding.UTF8.GetBytes(message);

                        channel.BasicPublish("", "q_A", null, body);
                        channel.BasicPublish("", "q_B", null, body);
                        Console.WriteLine(" [x] Sent {0}", message);
                        i++;
                        Thread.Sleep(1000);
                    }
