title: C# - HttpWebRequest POST (Login to Facebook)
body: <p>I'm trying to login to Facebook in my program and parse some information from there (like name, profile pic, etc).</p>
  
  <p>I'm getting redirected back to Facebook's main page everytime I execute the code below.</p>
  
  <pre><code>string email = "email";
  string pw = "pw";
  string PostData = String.Format("email={0}&amp;pass={1}", email, pw);
  
  CookieContainer cookieContainer = new CookieContainer();
  
  HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("");
  req.CookieContainer = cookieContainer;
  req.Method = "POST";
  req.ContentLength = PostData.Length;
  req.ContentType = "application/x-www-form-urlencoded";
  req.AllowAutoRedirect = true;
  req.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
  
  ASCIIEncoding encoding = new ASCIIEncoding();
  byte[] loginDataBytes = encoding.GetBytes(PostData);
  req.ContentLength = loginDataBytes.Length;
  Stream stream = req.GetRequestStream();
  stream.Write(loginDataBytes, 0, loginDataBytes.Length);
  
  HttpWebResponse webResp = (HttpWebResponse)req.GetResponse();
  
  Stream datastream = webResp.GetResponseStream();
  StreamReader reader = new StreamReader(datastream);
  webBrowser1.DocumentText = reader.ReadToEnd();
  
  foreach (Cookie cookies in webResp.Cookies)
  {
      MessageBox.Show(cookies.Name + "   " + cookies.Value);
  }
  </code></pre>
  
  <p>What am I doing wrong here? Any help would be appreciated, many thanks! :)</p>
  
  <p>edit:
  I found out how to do it shortly after I posted.</p>
  
  <p>Facebook sends a cookie everytime you visit it to see if you have cookies enabled, what I did was send a request to the login page of Facebook to get the cookies, then send another with the POST data. It worked this way and I successfully logged in.</p>
  
  <p>Thanks anyway! :)</p>
