在.net core控制台安装

Install-Package EasyNetQ

一：定义公共消息类

namespace Messages
{
    public class TextMessage
    {
        public string Text { get; set; } 
    }
}

二： 发布者代码

using System;
using EasyNetQ;
using Messages;

namespace Publisher
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var bus = RabbitHutch.CreateBus("host=localhost"))
            {
                var input = "";
                Console.WriteLine("Enter a message. 'Quit' to quit.");
                while ((input = Console.ReadLine()) != "Quit")
                {
                    bus.Publish(new TextMessage
                        {
                            Text = input
                        });
                }
            }
        }
    }
}

三： 订阅者代码

using System;
using EasyNetQ;
using Messages;

namespace Subscriber
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var bus = RabbitHutch.CreateBus("host=localhost"))
            {
                bus.Subscribe<TextMessage>("test", HandleTextMessage);

                Console.WriteLine("Listening for messages. Hit <return> to quit.");
                Console.ReadLine();
            }
        }

        static void HandleTextMessage(TextMessage textMessage)
        {
            Console.ForegroundColor = ConsoleColor.Red;
            Console.WriteLine("Got message: {0}", textMessage.Text);
            Console.ResetColor();
        }
    }
}
