I am trying to make a facebook open graph api call from inside by web application.I am making a web request using a C# request like this.\[code\]string token ="q2Fe0utty5gzCasPL23dTQYLDNlH5RSOiavNPJ4YNSs2We1+inyhAo9dsaLCMNa9u5l0tZS/g5IFdAa0v2qENKdSXIkLd1yPnYmSG695F3VCAknBxvdoYFQYI+mDqrZUqrXct5iM5cn0YeCdrIkojge/MJ0M2Q=="; string url = "https://graph.facebook.com/me?access_token=" + HttpUtility.UrlEncode(token) +"&response_type=id"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream receiveStream = response.GetResponseStream(); StreamReader readStream = newStreamReader(receiveStream,Encoding.UTF8); string responseData = http://stackoverflow.com/questions/12744393/readStream.ReadToEnd(); _context.SaveChanges();\[/code\]As the token has some special characters(+,/,==) in it i have encoded it using HttpUtility.UrlEncode(token) but still i get the following error.The remote server returned an error: (400) Bad Request. How do i go about fixing this error.I did the above things by seeing some response in stack-overflow,but still getting the error.Where did i go wrong?Thanks,In advance.
