Facebook API登录c#桌面应用程序

我正试图简单地连接到使用c#控制台应用程序的Facebook图形，但我有一个FacebookOAuth异常。下面是我到目前为止的代码:

       var client = new FacebookClient();
        // Exchange the code for an access token
        dynamic result = client.Get("/oauth/access_token", new
        {
            client_id = "****************",
            client_secret = "*****************************",
            redirect_uri = "http://www.teamdavix.com",
        });
        // Read the auth values
        string accessToken = result.access_token;
        DateTime expires = DateTime.UtcNow.AddSeconds(Convert.ToDouble(result.expires));
        var query = "SELECT author_uid, page_id, message FROM checkin WHERE page_id = 357981198572";
        dynamic parameters = new ExpandoObject();
        parameters.q = query;
        dynamic results = client.Get("/fql", parameters);
        Console.WriteLine(results);
        Console.ReadKey();
