Trace/Log SOAP XML Request and Response AND HTTP status code from SOAP .Net Client App

Question

I have C# .Net 2.0 App that is client of SOAP web services added to project through WebReferences. .Net creates convenient wrapper classes extending SoapHttpClientProtocol, so that everything like XML and serialization/deserialization of SOAP XML request/response in the communication is hidden.

I need to log the request and response to the WebServices and especially I want to have the HTTP status codes from the response the HTTP communication.

So far I have implemented SOAP Extension and to get the raw SOAP XML Requests/Responses, however I am unable to get the HTTP status code of the HTTP SOAP Response of the communication?

EDIT: So what I have is an instance of SoapHttpClientProtocol (generated by WSDL) and I want to get the HTTP status code from the communication.

I decompiled

private object[] ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, bool asyncCall)

Curiously there is this condition in it, which actually does not throw error when status 500?

if (num1 >= 300 && num1 != 500 && num1 != 400)
{
    throw new WebException(RequestResponseUtils.CreateResponseExceptionString(httpWebResponse, responseStream), null, WebExceptionStatus.ProtocolError, httpWebResponse);
}

---

EDIT2: So my problem generally is that I have response with HTTP status 500, which actually passes as success, without throwing WebException, due to the code above, which does not work for me, I want to detect such situation, that is why I need the HTTP status code.

HTTP/1.1 500 Internal Server Error

If you want the Http wrapper of the request/response, you can try something like this Call web APIs in C# using .NET framework 3.5.
