How to make request to web service with soap message - asp.net /C#

If you have web services and want to call the web service from your c# code, you can try to use this code example. The code example uses HttpWebRequest to create a request for the web service. 

Code Behind

         HttpWebRequest request = (HttpWebRequest)WebRequest.Create(<web service address>);  
         request.Headers.Add("SOAPAction", "http://tempuri.org/" + <web service method>);  
         request.ContentType = "text/xml;charset=\"utf-8\"";  
         request.KeepAlive = false;  
         request.Timeout = 300000; // - in millisecond. (5 minit)  
         request.Method = "POST";  
         request.Credentials = CredentialCache.DefaultCredentials;  
         byte[] byteArray = Encoding.ASCII.GetBytes(<data you want to send to webservice>);  
         request.ContentLength = byteArray.Length;  
         Stream s = request.GetRequestStream();  
         s.Write(byteArray, 0, byteArray.Length);  
         s.Dispose();  
         s.Close();  
         HttpWebResponse response = (HttpWebResponse)request.GetResponse();  
         Encoding enc = System.Text.Encoding.GetEncoding(1252);  
         StreamReader resStream = new StreamReader(response.GetResponseStream());  
         result = resStream.ReadToEnd(); // read webservice response
         dataToSend = "";  
         resStream.Dispose();  
         resStream.Close();  
         response.Close();  
         return result;
