Public class WebRequestHelper

Hr. Method = "POST ";
System. IO. Stream RequestStream = hr. GetRequestStream ();

System. Net. WebResponse response = hr. GetResponse ();
StreamReader reader = new StreamReader (response. GetResponseStream (), Encoding. GetEncoding ("UTF-8 "));
String ReturnVal = reader. ReadToEnd ();
