Question

我有这段代码，我使用rabbitmq client。我很好奇这是异步还是同步？如果是同步的，我怎么能让它异步？

        ConnectionFactory factory = new ConnectionFactory();
        factory.HostName = "localhost";
        using (IConnection connection = factory.CreateConnection())
        using (IModel channel = connection.CreateModel())
        {
            channel.QueueDeclare("hello", false, false, false, null);
            for (int i = 0; i < 1000; i++)
            {
                string message = "Hello World!";
                byte[] body = System.Text.Encoding.UTF8.GetBytes(message);

                channel.BasicPublish("", "hello", null, body);

            }

        }

见official C# client guide的第2.9章：

应用程序回调处理程序不得调用阻止AMQP操作（例如 IModel.QueueDeclare，IModel.BasicCancel或IModel.BasicPublish）。如果他们这样做，该频道将陷入僵局

BasicPublish是imho阻止同步操作。

RabbitMQ c＃客户端异步支持
