如何提取rabbitmq接收方法 [英] How to extract method for rabbitmq receive method

问题描述

大家好，我正在尝试用tutoria学习rabbitmq（ RabbitMQ - RabbitMQ教程 - 你好世界！ [ ^ ]）。当我想将接收代码块提取到NewMethod函数时，并在Main方法中使用NewMethod。我无法在队列中收到消息。任何人都可以提供帮助，非常感谢。

这是我的Receive.cs代码。

Hi everyone, I'm trying to learn rabbitmq with the tutoria(RabbitMQ - RabbitMQ tutorial - "Hello World!"[^]). When I want to extract the receieve code block to a function as NewMethod, and use the NewMethod in Main method. I cannot receive the message in the queue. Anyone can help, thanks a lot.
here are my Receive.cs code.

<pre> public static void Main()
    {
        Console.WriteLine("message from NewMethod:" + NewMethod());
        Console.ReadLine();
    }

    static string NewMethod()
    {
        string message = string.Empty;
        var factory = new ConnectionFactory() { HostName = "localhost" };
        using (var connection = factory.CreateConnection())
        using (var channel = connection.CreateModel())
        {
            channel.QueueDeclare(queue: "hello",
                                durable: false,
                                exclusive: false,
                                autoDelete: false,
                                arguments: null);
            var consumer = new EventingBasicConsumer(channel);
            consumer.Received += (model, ea) =>
            {
                var body = ea.Body;
                message = Encoding.UTF8.GetString(body);
                Console.WriteLine("[x] Received {0}", message);

            };
            channel.BasicConsume(queue: "hello",
                                noAck: true,
                                consumer: consumer);
        }
        return message;
    }
