我创建了一个用于演示的小类，它在特定端口上向rabbitmq发送一条消息：

class RabbitMqPublisher
{
    private IAdvancedBus _advancedBus;
    public RabbitMqPublisher()
    {
        _advancedBus = RabbitHutch.CreateBus("host=rabbitmq-server:5672;virtualHost=/;username=user;password=pass").Advanced;
    }

    public void PublishMessage(string message)
    {
        var routingKey = "SimpleMessage";

        // declare some objects
        var queue = _advancedBus.QueueDeclare("TestQueue.SimpleMessage");
        var exchange = _advancedBus.ExchangeDeclare("TestExchange.SimpleMessage", ExchangeType.Direct);
        var binding = _advancedBus.Bind(exchange, queue, routingKey);

        _advancedBus.Publish(exchange, routingKey, true, new Message<string>(message));
    }
}

在本例中，RabbitMQ服务器等待消息的端口是5672。除此之外，我的问题是，客户端使用什么端口发送此消息，是否可以配置它？
