如何在windows phone 8.1 winRT中使用facebook初始化获取用户数据？

我正在windows phone应用程序中开发facebook集成。我遵循了此链接

在我的类文件中：

class ContinuationManager
    {
        public void ContinueWith(IActivatedEventArgs args)
        {
            var rootFrame = Window.Current.Content as Frame;
            if (rootFrame == null)
                return;

            switch (args.Kind)
            {
                case ActivationKind.PickFileContinuation:
                    break;
                case ActivationKind.PickFolderContinuation:
                    break;
                case ActivationKind.PickSaveFileContinuation:
                    break;
                case ActivationKind.WebAuthenticationBrokerContinuation:
                    var continuator = rootFrame.Content as IWebAuthenticationBrokerContinuable;
                    if (continuator != null)
                        continuator.ContinueWithWebAuthenticationBroker((WebAuthenticationBrokerContinuationEventArgs)args);
                    break;
                default:
                    break;
            }
        }
    }

 interface IWebAuthenticationBrokerContinuable
    {
        void ContinueWithWebAuthenticationBroker(WebAuthenticationBrokerContinuationEventArgs args);
    }  

在上面的代码中，continuator获取null，因此下面的方法不调用

在我的主页中：

 public async void ContinueWithWebAuthenticationBroker(WebAuthenticationBrokerContinuationEventArgs args)
        {
            ObjFBHelper.ContinueAuthentication(args);
            if (ObjFBHelper.AccessToken != null)
            {
                fbclient = new Facebook.FacebookClient(ObjFBHelper.AccessToken);

                //Fetch facebook UserProfile:  
                dynamic result = await fbclient.GetTaskAsync("me");
                string id = result.id;
                string email = result.email;
                string FBName = result.name;

                //Format UserProfile:  
                GetUserProfilePicture(id);
                TxtUserProfile.Text = FBName;
                StckPnlProfile_Layout.Visibility = Visibility.Visible;
                BtnLogin.Visibility = Visibility.Collapsed;
                BtnLogout.Visibility = Visibility.Visible;
            }
            else
            {
                StckPnlProfile_Layout.Visibility = Visibility.Collapsed;
            }

Iam已成功登录，但未获取用户数据。我想获取用户数据。请任何人帮助我。

这里也有同样的问题。您应该在应用程序中标记页面：“

YourPageName:page，IWebAuthenticationBrokerContinuable”

你为我耍了把戏

您收到的数据是什么？有错误陈述吗？

结果的值是多少？您找到解决方案了吗？我也有同样的问题
