ASP.NET CORE combined with RabbitMq message queue - asp.net-core

Question

I am using asp.net core to create a project, I want to combine rabbitmq to realize the sending and receiving of message queue.I installed rabbitmq using docker and it runs successfully.But the queue I registered in the project is not displayed on the RabbitMq management interface.
ConnectionFactory factory = new ConnectionFactory
{
UserName = "guest",
Password = "guest",
HostName = "*******"
};
var connection = factory.CreateConnection();
var channel = connection.CreateModel();
channel.QueueDeclare("test", false, false, false, null);
Console.WriteLine("\nRabbitMQ enter exit to exit！");
string input;
do
{
input = Console.ReadLine();
var sendBytes = Encoding.UTF8.GetBytes(input);
channel.BasicPublish("", "test", null, sendBytes);
} while (input.Trim().ToLower()!="exit");
channel.Close();
connection.Close();
The above is my message production code.But there is no display on my RabbitMq dashboard.
enter image description here

You did not specify the port number to connect to and the VirtualHost to connect to, I am not sure if you are caused by this. Do you have a specific error? Or your project can run normally. I have written a demo for sending messages here, you can refer to it, it may be useful to you.
class Program
{
static void Main(string[] args)
{
try
{
var factory = new ConnectionFactory();
factory.VirtualHost = "/";
factory.HostName = "localhost";
factory.Port = 5672;
factory.UserName = "guest";//Default username guest
factory.Password = "guest";//Default password guest
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();
}
catch (Exception ex)
{
Console.Write(string.Format("RabbitMQ connection error :{0}\n", ex.ToString()));
}
}
}
Refer to the official document example:
https://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html
If you run this code and get this error:
Check if your corresponding virtual hosts match, I set "/" here, if you are not, please add your hosts here:
Result:
console:
rabbitmq:
