[rabbitmq-discuss] Decoding header fields

[Bernhard Mogens Ege]

Hmm, I guess I have to work a bit on how I send the information, then. In
effect, I send a message like this:

                IBasicProperties bp = channel.CreateBasicProperties();
                bp.Headers = new Dictionary<string,string>{ { "languageid",
"1" } };
                channel.BasicPublish(ExchangeName, routingKey, false, true,
bp, payload);

payload can be null or some byte array. The value string would in my case be
"0" or "1".

So I have to send it differently?

I would expect a byte array if the producer populated the field with a byte
array (prefixed by 'x'), but it could be any of AMQP table field type.
Consumers and producers may agree on types for certain keys beforehand, or
the consumer can determine the type at runtime using GetType().

See RabbitMQ.Client.Impl.WireFormatting.ReadFieldValue() for the relevant
implementation and mapping between AMQP types and .NET types.
