            string app_id = "aaaa";

            string app_secret = "aaa";

            string scope = "publish_stream,manage_pages";


            if (Request["code"] == null)
            {
                Response.Redirect(string.Format("https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}", app_id, Request.Url.AbsoluteUri, scope));
            }
            else
            {

                    app_id, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);

                HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;

                using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
                {
                    StreamReader reader = new StreamReader(response.GetResponseStream());

                    string vals = reader.ReadToEnd();

                    foreach (string token in vals.Split('&'))
                    {
                        tokens.Add(token.Substring(0, token.IndexOf("=")),
                            token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
                    }
                }

                string access_token = tokens["access_token"];
                dict.Add(access_token, null);

                var client = new FacebookClient(dict);
                
                client.Post("/me/feed", new { message = bodymessage });

Facebook可能使用OAuth 1.0。要与Facebook进行互动，您的代码必须遵循OAuth客户端协议。 DotNetOpenAuth是一个流行的OAuth库。它还提供了与google，hotmail，facebook等交互的示例代码。您可以在代码中使用此库。你在这做什么可能是正确的。但我不熟悉这种方法。我使用过DotNetOpenAuth库并且工作正常。

Facebook probably uses OAuth 1.0. To interact with facebook, your code has to follow OAuth client protocol. DotNetOpenAuth is a popular OAuth library. It also provides sample codes to interact with google, hotmail, facebook etc. You may use this library in your code. What you are doing here might be correct. But I am not familiar of such approach. I have used DotNetOpenAuth library and it worked fine.
