using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Identity.Client;
using Newtonsoft.Json.Linq;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
namespace DesignKGVC
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class GetUsersPage : ContentPage
    {
        public GetUsersPage()
        {
            InitializeComponent();
        }
        protected override async void OnAppearing()
        {
            // let's see if we have a user in our belly already
            try
            {
                var result = await App.AuthenticationClient.AcquireTokenSilentAsync(Constants.Scopes);
                GetUsersInfo(result.Token);
                await DisplayAlert("OK", "OK", "OK");
            }
            catch
            {
                // doesn't matter, we go in interactive more

            }
        }

        private async void btnlogi(object sender, EventArgs e)
        {
            try
            {

                var result = await App.AuthenticationClient.AcquireTokenAsync(
                Constants.Scopes,
                string.Empty,
                UiOptions.SelectAccount,
                string.Empty,
                null,
                Constants.Authority,
                Constants.SignUpSignInPolicy);
                GetUsersInfo(result.Token);


                // await DisplayAlert("OK", "OK", "OK");

            }
            catch (Exception)
            {
                //
            }


        }

        public async void GetUsersInfo(string token)
        {
            var client = new HttpClient();
            var request = new HttpRequestMessage(HttpMethod.Get,
                "https://graph.windows.net/me?api-version=1.6");
            request.Headers.Authorization =
                 new AuthenticationHeaderValue("Bearer", token);
            //new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", result.Token);

            var response = await client.SendAsync(request);
            var content = await response.Content.ReadAsStringAsync();
            if (response.IsSuccessStatusCode)
            {
                JObject user = JObject.Parse(content);


                lbldisplayname.Text = user["displayName"].ToString();
                lblmail.Text = user["otherMails"].ToString();


                // just in case
                // btnSignInSignOut.Text = "Sign out";


            }
            else
            {
                lbldisplayname.Text = "Api Call Dont Work";
                //DisplayAlert("Something went wrong with the API call", responseString, "Dismiss");
            }
        }

    }
}

and instead of geting display name and email, im geting "Api Call Dont Work" that i wrote in else condition so that i assume my Http Request is not succed, so what make that happen ? I tough there is no thing that i miss and i'm already get token that i send as parameter , or maybe b2c dont support Graph Api ? EDIT this is what i get when im using App Registration in Active Directory

Are you trying to get the signed in user's display name and email address? or other users? — spottedmahn, Oct 27 '17 at 12:23

To get the signed-in user's email address, you can select it as an Application Claim in the policy:

Decoded id token via jwt.ms

See this guide to query the B2C tenant that contains all of the users: Azure AD B2C: Use the Azure AD Graph API

Create App Registration and Key
Connect to AD Graph Api w/ the key

See this SO Post for Azure AD Graph API vs Micrsoft Graph API

but what i want is, to get the user from b2c portal, if i create app registeration and key and use it , isnt that make me not use b2c and using Azure Ad instead as a login ? – Theodorus Agum Gumilang Oct 30 '17 at 03:19
Using the Azure AD Graph will allow you to query all users that are in the B2C Tenant i.e. all users in the B2C portal. No, you will still be using B2C. – spottedmahn Oct 30 '17 at 14:19
bro i already tried using app registration but just like i said its using another portal to login, instead of login via kgvc aka my b2c name, its login via Graph Api (My App Registration in Active Directory) and thats make my users cant login there. any sugestion ? – Theodorus Agum Gumilang Oct 31 '17 at 03:32
