Post XML Data to an ASP.NET Page using C#

Code For Posting

To post XML, use the following function:

 WebRequest req = null;
 WebResponse rsp = null;
 try
 {
  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
  writer.WriteLine(this.GetTextFromXMLFile(fileName));
  writer.Close();
  // Send the data to the webserver
  rsp = req.GetResponse();

 }
 catch(WebException webEx)
 {

 }
 catch(Exception ex)
 {

 }
 finally
 {
  if(req != null) req.GetRequestStream().Close();
  if(rsp != null) rsp.GetResponseStream().Close();
 }Function to read xml data from local system
/// <summary>
/// Read XML data from file
/// </summary>
/// <param name="file"></param>
/// <returns>returns file content in XML string format</returns>
private string GetTextFromXMLFile(string file)
{
 StreamReader reader = new StreamReader(file);
 string ret = reader.ReadToEnd();
 reader.Close();
 return ret;
}

Code For Reading Posted Data

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(); 
}
