ASP.NET equivalent of this PHP code

Question

Please provide asp.net equivalent of this php code.

 $ip = $_REQUEST['ip']?$_REQUEST['ip']:$_SERVER["REMOTE_ADDR"];
 $client = new SoapClient(null, array(
  'location' => "http://www.itistimed.com/soap/whois-city.php",
  'uri'      => "http://www.itistimed.com/soap/req"));
 $data = $client->ipToCountryCity($ip);
 var_dump($data);

Will display something like:

array(7) { 
     ["status"] =>      int(1) 
     ["status_text"] => string(7)  "Success" 
     ["country"] =>     string(2)  "US" 
     ["city"] =>        string(13) "Mountain View" 
     ["state"] =>       string(2)  "CA" 
     ["zip"] =>         string(5)  "94043" 
     ["org"] =>         string(11) "Google Inc."
    } 

thanks.
