This article describes the function to post XML data to an ASP.NET page and then read the data on an ASP.NET page

Code For Posting

To post XML, use the following function:

   WebRequest req = null;
   WebResponse rsp = null;
    string fileName = "C:\test.xml";
    string uri = "http://localhost/PostXml/Default.aspx";
    req = WebRequest.Create(uri);
    //req.Proxy = WebProxy.GetDefaultProxy(); // Enable if using proxy
    req.Method = "POST";        // Post method
    req.ContentType = "text/xml";     // content type
    // Wrap the request stream with a text-based writer
    StreamWriter writer = new StreamWriter(req.GetRequestStream());
    // Write the XML text into the stream
    // Send the data to the webserver
    rsp = req.GetResponse();
   catch(WebException webEx)
   catch(Exception ex)
    if(req != null) req.GetRequestStream().Close();
    if(rsp != null) rsp.GetResponseStream().Close();
   }Function to read xml data from local system
  /// <span class="code-SummaryComment"><summary></span>
  /// Read XML data from file
  /// <span class="code-SummaryComment"></summary></span>
  /// <span class="code-SummaryComment"><param name="file"></param></span>
  /// <span class="code-SummaryComment"><returns>returns file content in XML string format</returns></span>
  private string GetTextFromXMLFile(string file)
   StreamReader reader = new StreamReader(file);
   string ret = reader.ReadToEnd();
   return ret;

Now, on the Web server in the ASP.NET page, write the following code to access the posted data:

private void Page_Load(object sender, EventArgs e)
     page.Response.ContentType = "text/xml";
    // Read XML posted via HTTP
    StreamReader reader = new StreamReader(page.Request.InputStream);
    String xmlData = reader.ReadToEnd();
