Call Soap service

using System;
using System.IO;
using System.Net;
using System.Text;
using System.Xml;
using System.Xml.XPath;
public class CallSoap {
  private const string soapNS = "http://schemas.xmlsoap.org/soap/envelope/";

    MemoryStream stream = new MemoryStream( );
    XmlTextWriter writer = new XmlTextWriter(stream,encoding);
    writer.WriteStartDocument( );
    writer.WriteStartElement("soap","Envelope",soapNS);
    writer.WriteStartElement("Body",soapNS);
    writer.WriteStartElement("GetNumberInStock",yourNS);
    writer.WriteElementString("productCode","1111");
    writer.WriteEndElement( );

    stream.Seek(0,SeekOrigin.Begin);
    StreamReader reader = new StreamReader(stream);

Invoke web service with Http Get

using System;
using System.IO;
using System.Net;
using System.Xml.XPath;
public class GetNumberInStockHttpGet {

    Stream stream = response.GetResponseStream( );
    XPathDocument document = new XPathDocument(stream);
    XPathNavigator nav = document.CreateNavigator( );
    XPathNodeIterator nodes = nav.Select("//int");
    Console.WriteLine(nodes.Current);
  }
}
