[rabbitmq-discuss] how to send a message including a array via .net client?

Tue Jan 4 10:22:47 GMT 2011

Hi Chen,

I like binary serialization at the moment.

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.formatter.aspx

In future I'd like to use binary Json, and there's also google protobuffers
which look pretty good (not sure on how good the .net support is though).
Json is certainly better IMHO than XML. The binary / cross-platform binary
options are more suited to my purposes.

Under .net Json / Binary / Soap serialization works just about the same way.

http://pietschsoft.com/post/2008/02/NET-35-JSON-Serialization-using-the-DataContractJsonSerializer.aspx

Start off serializing / deserializing an object with one property. Get that
going and you'll find it's the same set of steps for anything that inherits
from "object" (includes arrays).  Tag it up / decorate it correctly, and job
done.  Step two, see if Rabbit handles it faithfully (it does for me).

cheers,
-Steven
