Vista - WSStreamedHttpBinding : how does it works ?

Hi,

In a previous post I've a problem with transfering file using wshttpbinding.
An answer was to check the MS sample : WSStreamedHttpBinding in order to
allow using Stream in operation.

However, and even with the help shipped with the sample, I don't understand
what in the WSStreamedHttpBinding sample allow to use stream, there is no
reference of the stream class in the code...

Can someone explain why this binding sample allow transfert of stream ?

Thanks,
Steve

That because of "transfermode" attribute in config file ( look at
http://windowssdk.msdn.microsoft.com...nsfermode.aspx )
transferMode="Streamed"

I'm still having troubles to make it working.
Since I'm in a P2P pattern, host application acts both as client and server.
According one of your advise, I do not use the service reference dialog of
VS, but instead, I use the channelfactory :

ChannelFactory<IDestination> channelFactory = new ChannelFactory<IMyService
>(

new WSStreamedHttpBinding("StreamedBinding"),

new EndpointAddress(remoteUri)

);


IMyService proxy = channelFactory.CreateChannel();

proxy.DoIt(

File.OpenRead(sourceFile)

);

The app.config of the host (which is a console application) has this
configuration (only usefull lines are pasted) :

<service behaviorConfiguration="FileDestinationServiceBehavior"

name="MyService">

<endpoint binding="wsStreamedHttpBinding"
bindingConfiguration="StreamedBinding"

contract="IMyService" />

</service>

....

<bindings>

<wsStreamedHttpBinding>

<binding name="StreamedBinding" transferMode="Streamed"
securityMode="None"/>

</wsStreamedHttpBinding>

</bindings>



However, when the application reach the DoIt method, it throws an exception
saying the FileStream is not serializable... even if the transfertMode is
set to Streamed.



I'm quite lost in this quite simple prototype... What is wrong ?

Thanks in advance,

Steve

Actually, the doit method wait an argument which is not directly a stream,
but a small class (with other property I've not pasted for lisibility :

public class FileCopyInfo

{

private Stream m_rawFile;

[DataMember]

public Stream RawFile

{

get { return m_rawFile; }

set { m_rawFile = value; }

}

}



If I change my code to pass a Stream object instead of the FileCopyInfo
object with stream, the server side is correctly called.

Is there any limitation on putting stream properties in a datacontract
marked class ?

When you use stream , you stand that it stream of bytes only not
serializable class defined by DataContract. IMHO you can use both. Obviously
the data received, you can deserialize as you need
