Dictionary<string,string> fbParams = new Dictionary<string,string>();
            fbParams["message"] = Title;
            fbParams["caption"] = string.Empty;
            fbParams["description"] = string.Empty;
            fbParams["req_perms"] = "publish_stream";
            fbParams["scope"] = "publish_stream";
            //Initialize Your Facebook Client in the manner that suits you, I did it by supplying a saved access token from a single users
            FacebookWebClient fbClient = new FacebookWebClient(<YOUR_ACCOUNT_ACCESS_TOKEN>);
            //Get the listing of accounts associated with the user
            dynamic fbAccounts = fbClient.Get("/me/accounts");

            //Loop over the accounts looking for the ID that matches your destination ID (Fan Page ID)
            foreach (dynamic account in fbAccounts.data) {
                if (account.id == <DESTINATION_ID_OF_YOUR_FAN_PAGE>) {
                    //When you find it, grab the associated access token and put it in the Dictionary to pass in the FB Post, then break out.
                    fbParams["access_token"] = account.access_token;
                    break;
                }
            }
            //Then pass your destination ID and target along with FB Post info. You're Done.
            dynamic publishedResponse = fbClient.Post("/" + <DESTINATION_ID_OF_YOUR_FAN_PAGE> + "/feed", fbParams);

===================================

fbParams["access_token"] = account.access_token;
