SoapHeader class not instantiated during response deserialization
I had no problem creating a .Net web service that uses document binding style
and literal formatting that had both a SoapHeader on input for Authentication
and a SoapHeader on output for sending back general status information.
Unfortunately, I have to communicate with a web service that is using rpc
binding stype and encoded formatting. I have no problem sending the input
authentication SoapHeader up to the service provider's web service and I do
receive a response back with correct return parameters, but the class
associated with the output SoapHeader does not get instantiated during the
response deserialization process like it does in the implementation I stated
in the first paragraph.
Here's the .Net Web Service implementation:
public class Service1 : System.Web.Services.WebService
{
public AuthenticationHeader1 AuthHeader;
public callStatus1 ResponseStatus;
[WebMethod]
[SoapHeader("AuthHeader")]
[SoapHeader("ResponseStatus", Direction = SoapHeaderDirection.Out)]
public string HelloWorldEx(string name, int val)
{
ResponseStatus = new callStatus1();
if (AuthHeader.username == 45 && AuthHeader.password == "npa")
{
ResponseStatus.statusText = "Success";
ResponseStatus.statusCode = 0;
return "Hello World Ex";
}
else
{
ResponseStatus.statusText = "Unauthorized Access";
ResponseStatus.statusCode = 1;
return "Unauthorized Access";
}
}
}
Here's are the important portions of the proxy client for the web service
above:
[System.Web.Services.WebServiceBindingAttribute(Name="Service1Soap",
Namespace="http://tempuri.org/")]

System.Web.Services.Protocols.SoapHttpClientProtocol {

Here is the code that calls the proxy client:
private void LHTestEx()
{
Service1 dhs;
try
{
dhs = new Service1();
// To see the request turn the proxy on and run ProxyTrace
on 8080
// You will also need to change the web service URL to
192.168.1.178
// and it will fail, but at least you get to see the packet
going out
// in the ProxyTrace window
//WebProxy webProxy = new WebProxy("http://localhost:8080/",
false);
//dhs.Proxy = webProxy;
AuthenticationHeader1 ah = new AuthenticationHeader1();
ah.username = 111;
ah.password = "xxx";
dhs.AuthenticationHeader1Value = ah;
string result = dhs.HelloWorldEx("blah", 123);
int statusCode = dhs.callStatus1Value.statusCode;
string statusText = dhs.callStatus1Value.statusText;
MessageBox.Show(result);
}
catch (SoapHeaderException ex)
{
string s = ex.Message;
s = ex.Message;
}
catch (Exception ex)
{
string s = ex.Message;
s = ex.Message;
}
}

Below is the proxy client generated from the service provider's WSDL file
that is using RPC / encoded. Basically there is just the changes in the
Attributes to support SOAP serialization instead of XML serialization:
[System.Web.Services.WebServiceBindingAttribute(Name =
"DemoSoapBinding", Namespace = "https://centdev.liveglobalbid.com/Demo")]
public partial class DemoHandlerService :
System.Web.Services.Protocols.SoapHttpClientProtocol

Here is the calling code to the proxy client for the service provider's web
service:
private void LGBGetSaleCount()
{

try
{
dhs = new DemoHandlerService();
//WebProxy webProxy = new WebProxy("http://localhost:8080/",
false);
//dhs.Proxy = webProxy;
AuthenticationHeader ah = new AuthenticationHeader();
//callStatus cs = new callStatus();
ah.username = 111;
ah.password = "xxx";
dhs.AuthenticationHeaderValue = ah;
//dhs.callStatusValue = cs;
string result = dhs.getSaleCount("Binh", 5);
int statusCode = dhs.callStatusValue.statusCode;
string statusText = dhs.callStatusValue.statusText;
MessageBox.Show(result);
}
catch (SoapHeaderException ex)
{
string s = ex.Message;
s = ex.Message;
}
catch (Exception ex)
