ive searched everywhere and cannot find how to post data using vb.net
So i was wondering if someone can convert this curl code I made into vb.net :)

$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1"; 
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE ); // return into a variable
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec( $ch ); // run!
curl_close($ch);

$ Veri bir dizi değil, olsa vb.net nasıl çalışacağını emin olmak.
