I have use LinqtoTwitter api in my application. i want to update user profile image without that again asking for permission which i have taken accesstoken and oAuthToken info before. Here is my code and received error message;   Thanks a lot ..


IOAuthCredentials credentials = new SessionStateCredentials();

private MvcAuthorizer auth;
private TwitterContext twitterCtx;

if (credentials.ConsumerKey == null || credentials.ConsumerSecret == null)


                   credentials.ConsumerKey = ConfigurationManager.AppSettings["ConsumerKey"];

                   credentials.ConsumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"];


               credentials.OAuthToken = "db.OAuthToken";

               credentials.AccessToken = "db.AccessToken";

               auth = new MvcAuthorizer


                   Credentials = credentials


twitterCtx = new TwitterContext(auth);

if (auth.IsAuthorized)


          User user = twitterCtx.UpdateAccountImage(Server.MapPath("/images/n.jpg"));   ==> Error  : Error while querying Twitter.

Could you give me more info on the exception, like message and stack trace?  Also, could you pull up Fiddler2 and see what type of response you're getting from Twitter?  This will help me figure out what error you're receiving.
