Passing a very large collection via WCF streaming

Hi, guys!

I have to pass a huge number of some objects from my WCF service to a client. So, I configured my service to use strieamingresponse. The interface looks like:

[ServiceContract(Namespace = "http://www.xxx/SomeURI")]
public interface IHistoryRecoveryService
{		
  [OperationContract]
  Stream RecieveTrades (MarketFeed feed, TradeStamp start, TradeStamp end);		
}

Open in new window



But, all examples of streaming implementation are about passing some files (FileStream). Could anybody send me a link to a more complex example like my task?

I guess, I have to inherit "Stream" and implement my stream, retrieving my object from DB at calling Read.

Thanks

Thanks, Darren!

I implemented custom Stream as well as in the eaxample.

By the way: here (http://weblogs.asp.net/cibrax/archive/2008/06/10/streaming-large-content-with-wcf-and-deferred-execution.aspx) is an another approach.

But, it forces client to use XmlReader reader = message.GetReaderAtBodyContents(). I send my data  in binary format (serialized by ProtoBuff-Net).
