I'm trying to use a public webservice, which I have been using for years with other programming environment where you have to prepare everything at a lower level of coding, placing everything with hand( soap header, body, authantication etc). In VS2008 I have succeded referencing and accessing the web service. But I don't know how to invoke the request by sending the requested complex and simple elements and invoking the response and getting the return values. This is my code;

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Web;
using System.Web.Services;

namespace HowTo
     public partial class WEBSERVICE : Form
        HowTo.tr.gov.sgk.medula.ProvizyonGirisDVO oProvizyon=new HowTo.tr.gov.sgk.medula.ProvizyonGirisDVO();
        //HowTo.tr.gov.sgk.medula.HastaKabulIslemleriService   "This is the servise I like to use
        //HowTo.tr.gov.sgk.medula.ProvizyonGirisDVO  "This is the complex type that includes data to be sent
        //HowTo.tr.gov.sgk.medula.ProvizyonCevapDVO  "This complex element contains list of elements with return data elements

        public WEBSERVICE()


        private void button1_Click(object sender, EventArgs e)
            //this is where I like to use web service. Send request and get response


I appreciate any help

Thanks in advance


I generated the Web Reference and I have the proxy and I see the methods and services of Web Service. Question is how do I send a request ? Maybe this is a simple question but I just cannot see it. The link you mentioned did not help much

I invoked the method to send request data.Web service has received it and created the response. I can see it. But now I am struggling to read the returned data which contains complex element. So my problem nos is to fetch the returning data.

// execute the Request 
            proxy.hastaKabul(oProvizyon);// here I invoke hastaKabul method which also includes the response
// Below what I want to read (<sonucKodu>0503</sonucKodu>
