2. To use RabbitMQ in .NET, you need to download the RabbitMQ client assembly. You can go to the official website to download, download and decompress it and you can get RabbitMQ.Client.dll, which is the RabbitMQ client.

MQ_send (producer) class
public class MQ_Send
{
public static void SendMSG(string queue_str, string msg ,bool durable) {
var factory = new ConnectionFactory();
factory.HostName = "192.168.0.*";
factory.UserName = "****** ";
factory.Password = "**********";
using (var connection = factory.CreateConnection())
{
using (var channel = connection.CreateModel())

//bool exclusive is exclusive exclusive
//bool autoDelete is automatically deleted
//IDictionary<string, object> arguments other parameters

Main program:
static void Main(string[] args)
{
#region messages and queues are not persisted
for (int i = 0; i < 4; i++)
{
MQ_Send.SendMSG("hello1", "test", true);

Consumer main program:
static void Main(string[] args)
{
var factory = new ConnectionFactory();
factory.HostName = "192.168.0.*";
factory.UserName = "******";
factory.Password = "**********";
using (var connection = factory.CreateConnection())
using (var channel = connection.CreateModel())
{
channel.QueueDeclare(queue: "hello1",
durable: true,
exclusive: false,
autoDelete: false,
arguments: null);
channel.BasicQos(prefetchSize: 0, prefetchCount: 1, global: false);
Console.WriteLine(" [*] Waiting for messages.");
var consumer = new EventingBasicConsumer(channel);
consumer.Received += (model, ea) =>
{
var body = ea.Body;
var message = Encoding.UTF8.GetString(body);
Console.WriteLine(" [x] Received {0}", message);
channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
};
channel.BasicConsume(queue: "hello1",
noAck: false,
consumer: consumer);
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
}
}
It's over. In general, people who use persistence are lazy, and the code can be understood by the program directly.
