[rabbitmq-discuss] How to setup dead-letter queue in C# ?

Mon Dec 10 16:11:55 GMT 2012

I changed the code at some places, without any luck.

static void Main(string[] args)
{

    ConnectionFactory connectionFactory = new ConnectionFactory();
    connectionFactory.HostName = "10.57.244.205";

    IConnection connection = connectionFactory.CreateConnection();
    IModel channel = connection.CreateModel();

    //Declare default exchange
    channel.ExchangeDeclare("MessageQueueExchange", ExchangeType.Direct);
    Hashtable arguments = new Hashtable()
                                {
                                    {"x-dead-letter-exchange", "amq.fanout"}                                          
                                };
    channel.QueueDeclare("MessageQueue", true, false, false, arguments);
    channel.QueueBind("MessageQueue", "MessageQueueExchange",
"MessageQueue", null);

    //Queue message
    byte[] messageBody;
    MyMessage message = new MyMessage("ID-1");
    DataContractJsonSerializer serializer = new
DataContractJsonSerializer(typeof (MyMessage));
    using (MemoryStream memoryStream = new MemoryStream())
    {
        serializer.WriteObject(memoryStream, message);
        messageBody = memoryStream.ToArray();
    }

    IBasicProperties basicProperties = channel.CreateBasicProperties();
    basicProperties.ContentType = "application/json";
    basicProperties.DeliveryMode = 2;

    channel.BasicPublish("MessageQueueExchange", "MessageQueue",
basicProperties, messageBody);

    //DeQueue
    BasicGetResult result = channel.BasicGet("MessageQueue", false);

    //Negative Acknowledge
    channel.BasicNack(result.DeliveryTag, false, false);
}

Attached some screenshots with the exchanges/queues.
