Consuming Web Services using C#.NET


This is my first experience with SOAP webservices and I'm having problem in calling a function via SOAP web services.

I have add the web services by following the steps provided in msdn: add web reference, put in the uri, press enter, etc...

However, when I try to invoke the Login method. The return object is always null.

Below is the extracted web services wsdl:

- <wsdl:operation name="Login">
<soap:operation soapAction="" />
- <wsdl:input name="LogReq">
<soap:body use="literal" />
- <wsdl:output name="LogRes">
<soap:body use="literal" />

C# code:

SOAPServices proxy = new SOAPServices();
LogReq lReq = new LogReq();
LogRes lRes = new LogRes();

lReq.uname = txtUserName.Text.Trim();
lReq.pwd = txtPassword.Text.Trim();

lRes = proxy.Login(lReq); // The return object is always null

have u included a web service reference. if not then right click on your solution explorer and click "Add Web Reference" option and locate your web service. After that i your c# code, use the using directive as follows:

 using yourwebservicename;

then create its object and use it.
Hope this helps

Please dont forget to mark as answer if any post helps solve your problem.

What do users need to do to consume a .net web service?
