Code
For those of you scouring the web looking for a simple routine that sends/receives an XML file using HttpWebRequest/Response here ya go:
public static XmlDocument PostXMLTransaction(string v_strURL, XmlDocument v_objXMLDoc)
{
//Declare XMLResponse document
XmlDocument XMLResponse = null;
//Declare an HTTP-specific implementation of the WebRequest class.
HttpWebRequest objHttpWebRequest;
//Declare an HTTP-specific implementation of the WebResponse class
HttpWebResponse objHttpWebResponse = null;
//Declare a generic view of a sequence of bytes
Stream objRequestStream = null;
Stream objResponseStream = null;
//Declare XMLReader
XmlTextReader objXMLReader;
//Creates an HttpWebRequest for the specified URL.
objHttpWebRequest = (HttpWebRequest)WebRequest.Create(v_strURL);
try
{
//---------- Start HttpRequest
//Set HttpWebRequest properties
byte[] bytes;
bytes = System.Text.Encoding.ASCII.GetBytes(v_objXMLDoc.In nerXml);
objHttpWebRequest.Method = "POST";
objHttpWebRequest.ContentLength = bytes.Length;
objHttpWebRequest.ContentType = "text/xml; encoding='utf-8'";
//Get Stream object
objRequestStream = objHttpWebRequest.GetRequestStream();
//Writes a sequence of bytes to the current stream
objRequestStream.Write(bytes, 0, bytes.Length);
//Close stream
objRequestStream.Close();
//---------- End HttpRequest
//Sends the HttpWebRequest, and waits for a response.
objHttpWebResponse = (HttpWebResponse)objHttpWebRequest.GetResponse();
//---------- Start HttpResponse
if (objHttpWebResponse.StatusCode == HttpStatusCode.OK)
{
//Get response stream
objResponseStream = objHttpWebResponse.GetResponseStream();
//Load response stream into XMLReader
objXMLReader = new XmlTextReader(objResponseStream);
//Declare XMLDocument
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(objXMLReader);
//Set XMLResponse object returned from XMLReader
XMLResponse = xmldoc;
//Close XMLReader
objXMLReader.Close();

catch (WebException we)
