HI All
This is my code snippet

C#

var request = (HttpWebRequest)WebRequest.Create("http://xx.xx.xx.xx/xx/xx/xxx/xxx.aspx");
           var data1 = Encoding.ASCII.GetBytes(Url);
           request.Method = "POST";
           request.ContentType = "application/x-www-form-urlencoded";
           request.ContentLength = data1.Length;

           using (var stream = request.GetRequestStream())
           {
               stream.Write(data1, 0, data1.Length);
           }
           var response = (HttpWebResponse)request.GetResponse();
           var responseString =
                    new StreamReader(response.GetResponseStream()).ReadToEnd();

I assume you're trying to do all of this with code and not a browser?

You have to load the HTML into an XMLReader.

Read through the XML to find the form element and all the input elements.

Get the action attribute of the form element as this is the address to which you should post the form back to.

Get the value and name attributes from each of the input elements.

Then use the action and name, value pairs to build up a new WebRequest object.

Then submit the web request.
