如何使用C# RabbitMQ进行消息的发送和接收

要使用C# RabbitMQ进行消息的发送和接收，首先需要安装RabbitMQ的客户端库，可以使用NuGet包管理器来安装。然后，您需要编写发送和接收消息的代码。

以下是一个简单的示例代码，演示如何在C#中使用RabbitMQ发送和接收消息：

1. 发送消息：

using RabbitMQ.Client;
using System;
using System.Text;

class Program
{
    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);

            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();
    }
}

2. 接收消息：

using RabbitMQ.Client;
using RabbitMQ.Client.Events;
using System;
using System.Text;

class Program
{
    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();
        }
    }
}

在这个示例中，发送端将消息发送到名为“hello”的队列中，接收端从该队列中接收消息并打印到控制台。您可以根据需要修改代码来满足您的需求。
