FileStream transfer

Hello!

Which is the easiest way to transfer file stream

from server (service) side to client side

Thank you in advance.

Best regards,

Saso

Answer this question

FileStream transfer

Andre de Cav
Thank you for fast response. Exactly i would like to make download operation.
I will let you know if i encounter any problems making it.

Thank you once again and i hope that i don't bother you.

Sure.

[ServiceContract()]
public interface ISoftwaremakerSongService
{
[OperationContract()]
  Boolean Upload(Stream fileStream);
}

---

  public Boolean Upload(Stream fileStream)
  {
   Console.WriteLine("Saving Softwaremaker.mp3");
   DoSomeSaveFileRoutine("Softwaremaker.mp3", fileStream);
   return true;
  }

--- (No Security Binding on Http)

  <customBinding>
   <binding configurationName="MtomSoftwaremakerDemoNOSecurity">
    <contextFlow transactions="Ignore" transactionHeaderFormat="OleTx"
    <httpTransport manualAddressing="false" maxMessageSize="65536"
     authenticationScheme="Anonymous" bypassProxyOnLocal="false"
     hostnameComparisonMode="StrongWildcard" mapAddressingHeadersToHttpHeaders="true"
     proxyAuthenticationScheme="Anonymous" realm="" transferTimeout="00:01:00"
     useSystemWebProxy="true" />
    <mtomMessageEncoding />
   </binding>
  </customBinding>

Ok, here is the code.

-----------------------------------------------------
// SERVICE

[OperationContract]
public bool Upload(FileStream fs)
{
   // Create the writer for data.
   BinaryWriter w = new BinaryWriter(fs);
   // Write data
   for (int i = 0; i < 100; i++) w.Write((int)i);
   w.Close();
   return (true);
}

-----------------------------------------------------
// CLIENT

using (StockQuoteProxy proxy = new StockQuoteProxy("StockQuoteEndpoint"))
{
   FileStream fs = new FileStream("c:\\test.mp3", FileMode.CreateNew);
   bool b = proxy.Upload(fs);
   fs.Close();
   proxy.Close();
}

-----------------------------------------------------
When i run svcutil and parameter in service operation is FileStream, then i get following exception:

Error: Unable to obtain Metadata from the Uri provided
Error:   WS-MetadataExchange Failed on URI:http://localhost/stock/service.svc
    There was no endpoint listening at http://localhost/stock/service.svc that c

ction, among other things.

The error message from each known type may help you fix the problem:

All i want is to transfer file stream in both directions, "client->server" and "server->client". Please make your own web.config, app.config and write the service operation, which will accept FileStream parameter (upload) and service operation, which will return FileStream (download).

THANK YOU.

I would just stream over the filestream using MTOM encoding
Frank VDL
Softwaremaker,

The command "svcutil.exe config:/app.config" successfully generated a corresponding client.config file, also service and client compiled without problems, but i still can't get file stream from service to client side.

I'm asking you, if there is any chance to make entire vs.net project, with all corresponding files, that will demonstrate how to transfer file stream.

If it possible, attach the project here in forum, otherwise send it to my email.

Sorry for bothering you, but i need to solve that problem as soon as possible.

Than you once again.

Saso
Martin Kristensen
Saso,

It seems that you have missed out the <customBinding> in your web.config Put the same blob of <bindings><customBinding> that I indicated to you in my earlier posts on the config on both sides.
cubeberg
What is the exception you are seeing I suspect it could be a proxy instantiating problem or are you using channelfactories

Do a simple filestream upload operation and post it here (client and service code + the config files)
Sathya
No worries. Let me know if this works and do "Mark as Correct Answer" if it is so others can learn from this as well.
amundra
> Now I can't even run simple service operation on client side. Previosuly i was using wsProfileBindig. Should i also change web.config file Currently is configured like this:

Your bindings used on the client is not the same as the ones used for the server. The best way would be to use a svcutil.exe config:/app.config to generate a corresponding client.config file. You have to make sure the bindings do correspond to each other or else it wont work.

Softwaremaker, i configured app.config file on client side as follows:

Now I can't even run simple service operation on client side. Previosuly i was using wsProfileBindig. Should i also change web.config file Currently is configured like this:

First of all, thank you once again for your fast responses. I examined in details your post, and noticed, that i have syntax error in my web.config file. Then i made it up and since that everything compiles without errors, but when i run client, the exception is still there. <Exception: Unsupported Media Type> Because i need IIS hosted application, i'm using proxy solution. Config files are the same as yours. Enclosed are service and client source files, web.config, app.config and exception message.

Softwaremaker, could you be so kind and write short example.

Thank you.

What do you see when you point your brower to http://localhost/stock/service.svc

My guess is that your soln is failing at the service-side. This could be related to incorrect settings such as the loading of the wrongtype, etc

I am using Indigo B2-ctp now so my bits are slightly different than what you have. I will put my codes in here again. Take note of the loading of the types. I suspect this is where your sevice fails.

As you will see below, I am simulating both sides using a console-hosted application. Once you get the hang of this, port it over to your .svc implementation for a IIS-hosted one

[WilliamTay] As you can see, I am using b64Encoding above. You can uncomment that and use mtomMessageEncoding if you would like for a more optimized approach.

--- Copy the same IEchoService to the client-side. I am using channelFactories to instantiate a channel and not a proxy. I prefer it this way in proof of concepts and such. Of course, you can still do the proxy way.
