C# Service Client - Transfer-Encoding: Chunked

Question

I'm currently trying to fix my SOAP-Client in C#, but got somehow stuck with the Transfer-Encoding. I'm more or less a newbie to C#, so it's completly possible that im just missing something minor here.

I consumed a SOAP service from our local Tomcat Server following this: https://web.archive.org/web/20180506023052/http://www.csharptutorial.in/37/csharp-net-how-to-consume-a-web-service-in-csharp-net-visual-studio-2010

My current code:

using System;
using ConsoleApp1.Lims;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            LimsZugriffService client = new LimsZugriffService();
           // FunktionsErgebnis response = client.connect();
           // Console.WriteLine("Connect" + response.meldung);
            String[] bond = new String[] { "versuch.auftrag.nr=2014/0031" };
            String[] bondFail = new String[] { "abc" };
            VersuchsschrittErgebnis reponseVersuch = client.ermittleVersuchsschritte(bond);
            Console.WriteLine(reponseVersuch.ermittelteVersuchsschritte.Length);
            Console.WriteLine(reponseVersuch.meldung);

        }
    }
}

After some testing I found out, that something does not work as intended. My Response-Array of <ermittelteVersuchsschritte> seems to be empty, while the "control"-Flags are parsed normally.

I captured the traffic between client and server to figure out what was wrong and it was actually completly there. Just chunked into 8192 Byte blocks.

Could it be, that the C# implementation of the WebClient got some problems with Transfer-Encoding: Chunked ?

After googling for some hours i could not find a satisfiying solution to this issue. I hope somebody, who knows C# and WebServices better than me has the answer.

For the sake of completeness:

My WSDL

My Traffic - Request->Response

Answer 1

After some researching, trial and error and much time I finally figured out my mistake.

C# seems not to have a problem with the Transfer-Encoding: Chunked

The mistake was on the service side. The consumed wsdl was generated from java code with the help of Axis (the first Axis not Axis2 ). Axis generated a wsdl 1.0 while C# seems to expect wsdl 2.0 . So in the end, the XML-structure described in the wsdl was flawed and could not be automatically consumed.

We fixed this problem by switching from Axis to Apache CXF . The newly generated wsdl was than consumed without a problem at our C# - client side.
