I am using the below code which I got from MSDN to send an XML Data via HTTP Post to a server running a PHP script. I receive a response from the server but it does not recieve my XML data.

The response I get is that no XML data is received by the PHP script. I tried changing my encoding to UTF8 but it did not change anything. I am using .NET 4.0

Any hints or tips will be greatly appreciated.

using System;
using System.IO;
using System.Net;
using System.Text;

namespace Examples.System.Net
    public class WebRequestPostExample
        public static void Main()
            // Create a request using a URL that can receive a post. 
            WebRequest request = WebRequest.Create("http://stage05.fujifilmimagine.com/phototellerphp/job_tracking.php");
            // Set the Method property of the request to POST.
            request.Method = WebRequestMethods.Http.Post;

            // Create POST data and convert it to a byte array.
            string postData = "<XML><JOB_NO>JOB~AAA012238</JOB_NO><JOB_STATUS_ID>21</JOB_STATUS_ID><STATUS_DESCRIPTION>Has been downloaded</STATUS_DESCRIPTION></XML>"; 
            byte[] byteArray = Encoding.ASCII.GetBytes(postData);
            // Set the ContentType property of the WebRequest.
            request.ContentType = "application/x-www-form-urlencoded";
            // Set the ContentLength property of the WebRequest.
            request.ContentLength = byteArray.Length;
            // Get the request stream.
            Stream dataStream = request.GetRequestStream();

            // Write the data to the request stream and send it now
            dataStream.Write(byteArray, 0, byteArray.Length);
            // Close the Stream object.

            // Get the response.
            WebResponse response = request.GetResponse();
            // Display the status.
            // Get the stream containing content returned by the server.
            dataStream = response.GetResponseStream();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader(dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd();
            // Display the content.
            // Clean up the streams.
