我希望有人可以幫助我,我試圖創建一個連接到辦公室365以提取聯繫信息的xamarin android應用程序。如果你的谷歌「在你的應用程序中放一些office 365」,並且打開第一個鏈接,我可以找到我正在遵循的教程。作者是Mayur Tendulkar。Xamarin.Android Office 365身份驗證
我能夠將連接的服務添加到我的應用程序和所有程序集下載,儘管可以從教程(ActiveDirectorApiSample,CalendarApiSample等)的步驟4的屏幕截圖中看到的示例cs文件不會被添加到我的項目中:http://i.imgur.com/olLfjoN.png
當試圖添加EnsureClientCreated()方法的Visual Studio警告我說,Authenticator的命名空間找不到,所以我嘗試添加它:

我注意到,Visual Studio中嘗試使用Xamarin的補充。 Auth,但是如果我檢查教程中的源代碼我下面的Xamarin.Auth參考是不是有:
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using System.Threading.Tasks;
using System.Collections.Generic;
using Microsoft.Office365.Exchange;
using Microsoft.Office365.OAuth;
using System.Linq;
namespace O365Client
{
[Activity(Label = "O365 Client", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : ListActivity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
GetMessages (this);
}
const string ExchangeResourceId = "https://outlook.office365.com";
const string ExchangeServiceRoot = "https://outlook.office365.com/ews/odata";
public async Task<IEnumerable<IMessage>> GetMessages(Context context)
{
var client = await EnsureClientCreated(context);
var messageResults = await (from i in client.Me.Inbox.Messages
orderby i.DateTimeSent descending
select i).ExecuteAsync();
MyGlobalDeclaration.Messages = messageResults.CurrentPage.ToList();
ListAdapter = new HomeScreenAdapter(this, MyGlobalDeclaration.Messages);
return messageResults.CurrentPage;
}
private async Task<ExchangeClient> EnsureClientCreated(Context context)
{
Authenticator authenticator = new Authenticator(context);
var authInfo = await authenticator.AuthenticateAsync(ExchangeResourceId);
return new ExchangeClient(new Uri(ExchangeServiceRoot), authInfo.GetAccessToken);
}
protected override void OnListItemClick (ListView l, View v, int position, long id)
{
var bodyActivity = new Intent (this, typeof(MessageBodyActivity));
bodyActivity.PutExtra ("Id", v.Tag.ToString());
StartActivity (bodyActivity);
}
}
}
如果我使用Xamarin.Auth然後與Visual Studio錯誤:無法創建抽象類或接口的實例「Xamarin.Auth.Authenticator」
任何人都可以確認我如何解決Authenticator錯誤?
