.NET Forum / ASP.NET / General / March 2008WCF FileStreams
Sorry for the cross post but his group is far more active. I have a need to pass mutiple file streams in WCF Is this possible? I can do this as a regular web service. Simply pass a FileStream[] filled with file streams. But don't how to do this with WCF thanks you can't do it with a webservice either. file streams are not serializable, so can not be sent over either service. you need to create you own file stream objects that are. just serialize the context info (filename, current offset), then when the client does a read from the stream, your stream object makes a call back to the server to get another block of data. on the server side, open the file, seek to the offset, then return a block of data, then close the file. -- bruce (sqlwork.com) > Sorry for the cross post but his group is far more active.

How did you get it to work even in the same solution? How did it serialize as a webservice?  SignatureRegards, Alvin Bruney [MVP ASP.NET] [Shameless Author plug] The O.W.C.

I'm not an expert with c# or wcf but I smply created an arry of filestreams and passed them. It worked fine. I have since tried different projects and run into issues. I am now getting an error saying timeouts are not supported in this stream.I have a co-worked who claimns he is passing a stream with Message header and Message body but he can only do one at a time.
