Get html result from web page

Question

I am planning create a movil application (for fun) that should use the result from this web page (http://consultawebvehiculos.carabineros.cl/index.php). is there any ways to create a instance of a browser in my Net code and read this result and publish it using a web service.. something like:

var IE= new broswer("http://consultawebvehiculos.carabineros.cl/index.php");
var result=IE.FindElementByID("txtIdentityCar").WriteText(YourIdentityCar);
publicToWebSerivce(result);

Update: Using Fiddler i can see that http post is somthing like that:

POST http://consultawebvehiculos.carabineros.cl/index.php HTTP/1.1
Host: consultawebvehiculos.carabineros.cl
Connection: keep-alive
Content-Length: 61
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Origin: http://consultawebvehiculos.carabineros.cl

Content-Type: application/x-www-form-urlencoded
Referer: http://consultawebvehiculos.carabineros.cl/index.php
Accept-Encoding: gzip,deflate,sdch
Accept-Language: es-ES,es;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

May be i need some .Net class like webclient in order connect with the php page...no sure.

UPDATE: I finally i found the solution using Fiddler to know the total parameters and I've used the code from http://www.hanselman.com/blog/HTTPPOSTsAndHTTPGETsWithWebClientAndCAndFakingAPostBack.aspx

If your are just interested in scraping the page, I suggest using Html Agility Pack.

If you also want to display the page, then you could use the WebBrowser control.

What i would like to do with the page is: 1) connect with the php page. 2) add input to the page. 3) send this information using http post. 4) wait for the response and check the html.

We've been using http://htmlunit.sourceforge.net/ for similair tasks. It allows you to send requests, receive response/status code/etc.

(it's a Java lib, so you could either google for a .Net port or use a converter to convert Java assembly into .Net assembly - see http://blog.stevensanderson.com/2010/03/30/using-htmlunit-on-net-for-headless-browser-automation/ for guidance. We've used the convertion approach).
