Comment passer les paramètres POST à la requête Web ASP.Net?

J'essaie de faire des demandes Web par programme dans ASP.NET, en utilisant la méthode POST.
Je voudrais également envoyer des paramètres POST avec la demande Web. Quelque chose comme ceci:

WebRequest req = WebRequest.Create("accounts.craigslist.org/login/pstrdr");
    req.Method = "POST";
    req.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
    //WebRequest.Parameters.add("areaabb","hou");

évidemment la ligne commentée ne fonctionne pas. Comment puis-je y parvenir?

Essayez comme ça ...

  string email = "YOUR EMAIL";
  string password = "YOUR PASSWORD";

  string URLAuth = "https://accounts.craigslist.org/login";
  string postString = string.Format("inputEmailHandle={0}&name={1}&inputPassword={2}", email, password);

  const string contentType = "application/x-www-form-urlencoded";
  System.Net.ServicePointManager.Expect100Continue = false;

  CookieContainer cookies = new CookieContainer();
  HttpWebRequest webRequest = WebRequest.Create(URLAuth) as HttpWebRequest;
  webRequest.Method = "POST";
  webRequest.ContentType = contentType;
  webRequest.CookieContainer = cookies;
  webRequest.ContentLength = postString.Length;
  webRequest.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1";
  webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
  webRequest.Referer = "https://accounts.craigslist.org";

  StreamWriter requestWriter = new StreamWriter(webRequest.GetRequestStream());
  requestWriter.Write(postString);
  requestWriter.Close();

  StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
  string responseData = responseReader.ReadToEnd();

  responseReader.Close();
  webRequest.GetResponse().Close();
