[Mediawiki-l] Beginners help .Net and formatting the POST Request

[Nick Jones]

Hi guys,

I would be very grateful if someone could give me an indication of how to build up the request to the API. Just for a simple page query. I have some code that uses Web request/response which works with other API's but it does not work with the mediawiki api. I would be verya grateful if anyone could help me out. I one of the methods I have tried below:
I consistenly get a  "The remote server returned an error: (417) Expectation failed." Error.


string pgTitle = txtPageTitle.Text;

        Uri address = new Uri("http://en.wikipedia.org/w/api.php");

       HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;

        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";


        string action = "query";
        string query = pgTitle;

        StringBuilder data = new StringBuilder();
        data.Append("action=" + HttpUtility.UrlEncode(action));
        data.Append("&query=" + HttpUtility.UrlEncode(query));

        byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());


        request.ContentLength = byteData.Length;

        using (Stream postStream = request.GetRequestStream())
        {
            postStream.Write(byteData, 0, byteData.Length);
        }

          using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
        {
            // Get the response stream
            StreamReader reader = new StreamReader(response.GetResponseStream());


            divWikiData.InnerText = reader.ReadToEnd();
        }
