I have looked at this, but calling it via my C# code and parsing the XML is my issue?

what are all the Common URL Parameters you using in your c# code? is the outFormat xml or json?

can you give me your sample url without key value. also what error you are getting while parsing the response?
Here is some php code that will do the job if that helps?

      function distance($lat1, $lon1, $lat2, $lon2, $unit) {
        $theta = $lon1 - $lon2;
        $dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) +  cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta));
        $dist = acos($dist);
        $dist = rad2deg($dist);
        $miles = $dist * 60 * 1.1515;
        $unit = strtoupper($unit);
        if ($unit == "K") {
          return ($miles * 1.609344);
        else if ($unit == "N") {
            return ($miles * 0.8684);
        else if ($unit == "Y") {
            return ($miles * 1760);
            else {
              return $miles;
      echo distance(50.850, -0.75838, 50.850, -0.85838, "M") . " Miles<br>";
      echo intval(distance(50.840, -0.89838, 50.849, -0.89838, "Y")) . " Yards<br>";
      echo distance(53.632293, -0.89838, 53.623393, -0.89838, "K") . " Kilometers<br>";
      echo distance(50.84316, -0.89838, 50.84317, -0.89838, "N") . " Nautical Miles<br>";
