TextBox动态文本

本文关键字：文本 动态 TextBox | 更新日期: 2024-08-01 23:03:00

我正在开发一个应用程序，需要在其中设置一些来自facebook的用户数据。因此，使用WebAuthentication代理，我让用户登录，然后获取信息并将其设置为文本框值。信息被正确地获取，但是在Textbox中没有设置值。我想不出原因。有人能帮忙吗？

async public void SignUpUsingFacebook(string response)
    {            
        if (Utility.isInternetAvailable())
        {
            try { MainPage.StartAnimation();
            MainPage.loaderGrid.Visibility = Visibility.Visible;
            }
            catch
            {
                setAnimation();
                StartAnimation();
                loaderGrid.Visibility = Visibility.Visible;
            }
            string token = response.Substring(response.IndexOf('=') + 1);
            string fbGetInfo = "https://graph.facebook.com/me?access_token=" + token;
            HttpResponseMessage msg = await new HttpClient().GetAsync(new Uri(fbGetInfo), HttpCompletionOption.ResponseContentRead);
            if (msg.IsSuccessStatusCode)
            {
                try
                {
                    string fbData = await msg.Content.ReadAsStringAsync();
