Hi Omar,
string strResult = result.Text;
ServiceReference1.nwebserviceClient req = new ServiceReference1.nwebserviceClient();
req.aaCheck(username.Text, password.Text,ref strResult);

Hi,
Try this Code:
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("SOAPAction", action);
webRequest.ContentType = "text/xml;charset=\"utf-8\"";
webRequest.Accept = "text/xml";
webRequest.Method = "POST";
XmlDocument soapEnvelopeDocument = new XmlDocument();
soapEnvelopeDocument.LoadXml(@""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/1999/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/1999/XMLSchema"">"http://tempuri.org/"" SOAP-ENV:encodingStyle=""http://schemas.xmlsoap.org/soap/encoding/"">"xsd:integer"">12"xsd:integer"">32");
using (Stream stream = webRequest.GetRequestStream())
{
    soapEnvelopeXml.Save(stream);
}
