title: Sending and receiving data from web service in winform
body: <p>I wrote a WinForm application which should use a Web service to retrieve needed information.
  the address is <a href="http://www.portaltvto.com/index.php/azmoonse/electronic_gavahi_srv/getstudent?wsdl" rel="nofollow">this</a> :</p>
  
  <p>I read some articles here and in msdn and also added service reference to my project but when I want to use the methods I can't.</p>
  
  <p>Now I've got confused. I need to send username and password to service and after authenticating send an ID and the web service sends back the appropriate information then I need to send back the log of what I've received. Is it possible through WinForm ? How can I do it?</p>
  
  <p>Some sample code or reference would be appriciatted. </p>
