RABBITMQ Message Queue (ii): "Hello, World" [Turn]

2. Sending

First program Send.cs: Send Hello World to queue. As we mentioned in the previous article, the 9th line of your program is to establish a connection, the 12th line is to create a channel, and the 14th line creates a queue named Hello.

1 usingSystem;2 usingrabbitmq.client;3 usingSystem.Text;4 5 classSend6 {7      Public Static voidMain ()8     {9         varFactory =NewConnectionFactory () {HostName ="localhost" };Ten         using(varConnection =Factory. CreateConnection ()) One         { A             using(varChannel =connection. Createmodel ()) -             { -Channel. Queuedeclare ("Hello",false,false,false,NULL); the                 stringMessage ="Hello world!"; -                 varBODY =Encoding.UTF8.GetBytes (message); -Channel. Basicpublish ("","Hello",NULL, body); -Console.WriteLine ("[x] Sent {0}", message); +             } -         } +     } A}

As you can see from the architecture diagram, producer can only be sent to exchange, and it cannot be sent directly to the queue.

Line 17th: Now we use the default Exchange (the name is a null character). This default Exchange allows us to send to the specified queue. Routing_key is the specified queue name.

3. Receiving

The second program Receive.cs will get a message from the queue and print to the screen.

1 usingrabbitmq.client;2 usingRabbitMQ.Client.Events;3 usingSystem;4 usingSystem.Text;5 6 classReceive7 {8      Public Static voidMain ()9     {Ten         varFactory =NewConnectionFactory () {HostName ="localhost" }; One         using(varConnection =Factory. CreateConnection ()) A         { -             using(varChannel =connection. Createmodel ()) -             { theChannel. Queuedeclare ( "hello" ,false,false,false,NULL); -                 varConsumer =New Queueingbasicconsumer(channel); -Channel.Basicconsume("Hello",true, consumer); -Console.WriteLine ("[*] waiting for messages."+"To exit Press CTRL + C"); +                  while(true) -                 { +                     varEA =(Basicdelivereventargs) consumer. Queue.dequeue ();//Blocking A                     varBODY =ea. Body; at                     varMessage =Encoding.UTF8.GetString (body); -Console.WriteLine ("[x] Received {0}", message); -                 } -             } -         } -     } in}

4. Final Run

Run Send.cs First, andSend.cs will stop each time it finishes running. Note: The data is now stored in the queue. After receiving it receive. cs.
