WCF FileStreams

[CsaaGuy]

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.

Thats a bummer, i was able to do it when it was in the same solution
with different projects so i was hoping it could be done.

How did you get it to work even in the same solution? How did it serialize
as a webservice?

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.
