新建控制台項目 Sender，Receiver

添加 nuget 包：RabbitMQ.Client

發送端

namespace Sender
{
    class Sender
    {
        public static void Main()
        {
            var factory = new ConnectionFactory() { HostName = "localhost" };
            using (var connection = factory.CreateConnection())
            {
                using (var channel = connection.CreateModel())
                {
                    channel.QueueDeclare(queue: "hello",
                        durable: false, // 持久化
                        exclusive: false, // 排它
                        autoDelete: false, // 自動刪除
                        arguments: null);

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

                    channel.BasicPublish(exchange: "",
                        routingKey: "hello",
                        basicProperties: null,
                        body: body);
                    Console.WriteLine(" [x] Sent {0}", message);
                }

                Console.WriteLine(" Press [enter] to exit.");
                Console.ReadLine();
            }
        }
    }
}

接收端

namespace Receiver
{
    class Receiver
    {
        public static void Main()
        {
            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.ToArray();
                    var message = Encoding.UTF8.GetString(body);
                    Console.WriteLine(" [x] Received {0}", message);
                };
                channel.BasicConsume(queue: "hello",
                    autoAck: true,
                    consumer: consumer);

                Console.WriteLine(" Press [enter] to exit.");
                Console.ReadLine();
            }
        }
    }
}

rabbitmq container

docker run -d -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management

運行成功後可以訪問（localhost 替換為伺服器地址）

//localhost:15672/#/

用戶名密碼默認為 guest

替換髮送端，接收端的 localhost 為伺服器地址

發送資訊

先啟動接收端，再啟動發送端

發送多條資訊

Sender

channel.QueueDeclare(queue: "hello",
    durable: false, // 持久化
    exclusive: false, // 排它
    autoDelete: false, // 自動刪除
    arguments: null);

Console.WriteLine("Please input your message with enter:");
string message = Console.ReadLine();
while (message != "EXIT")
{
    var body = Encoding.UTF8.GetBytes(message);

    channel.BasicPublish(exchange: "",
        routingKey: "hello",
        basicProperties: null,
        body: body);
    Console.WriteLine(" [x] Sent {0}", message);

    Console.WriteLine("Please input your message with enter:");
    message = Console.ReadLine();
}

先啟動接收端，再啟動發送端
