c# - Live SDK - 尝试在没有 SignInButton 的情况下登录

Question

有什么方法可以登录到应用程序（Silverlight，WP7 可以）而无需单击登录按钮。

我想动态登录我，例如：当你启动应用程序时，我想登录我。如何在不使用按钮的情况下做到这一点？

Answer 1

我想出了怎么做，所以我决定分享：

using System.Windows;
using Microsoft.Live;

public class LiveLogin
{

    private static readonly string[] scopes = 
        new string[] { 
            "wl.signin", 
            "wl.basic", 
            "wl.calendars", 
            "wl.calendars_update", 
            "wl.contacts_calendars", 
            "wl.events_create" };

    private LiveAuthClient authClient;
    private LiveConnectClient liveClient;


    public LiveLogin()
    {
        this.authClient = new LiveAuthClient("**your client id here**");
        this.authClient.InitializeCompleted += authClient_InitializeCompleted;
        this.authClient.InitializeAsync(scopes);
    }

    private void authClient_InitializeCompleted(object sender, LoginCompletedEventArgs e)
    {
        if (e.Status == LiveConnectSessionStatus.Connected)
        {
            this.liveClient = new LiveConnectClient(e.Session);
        }
        else
        {
            this.authClient.LoginCompleted += authClient_LoginCompleted;
            this.authClient.LoginAsync(scopes);
        }
    }

    private void authClient_LoginCompleted(object sender, LoginCompletedEventArgs e)
    {
        if (e.Status == LiveConnectSessionStatus.Connected)
        {
            this.liveClient = new LiveConnectClient(e.Session);
            MessageBox.Show("Signed");
        }
        else
        {
            MessageBox.Show("Failed!");
        }
    }
}

很好的答案理查德。这真的很有帮助。

我注意到有人抱怨他们找不到 InitializedCompleted 事件的一些评论。如果您在 .Net 4.5 中进行编码，那么您需要遵循异步方法的 async/await 模式。上面的类看起来像这样：

public class LiveLogin
    {
        private static readonly string[] Scopes =
            new[]
                {
                    "wl.signin",
                    "wl.basic",
                    "wl.calendars",
                    "wl.calendars_update",
                    "wl.contacts_calendars",
                    "wl.events_create"
                };

        private LiveAuthClient _authClient;



        public async Task<LiveConnectClient> Login()
        {
            _authClient = new LiveAuthClient("**your client id here**");

            LiveLoginResult result = await _authClient.InitializeAsync(Scopes);
            if (result.Status == LiveConnectSessionStatus.Connected)
            {
                return new LiveConnectClient(result.Session);
            }
            result = await _authClient.LoginAsync(Scopes);
            if (result.Status == LiveConnectSessionStatus.Connected)
            {
                return new LiveConnectClient(result.Session);
            }
            return null;
        }


    }

MS在这里有一个异步等待入门

感谢代码示例 - 帮助我想出了 Windows Phone 8 等的代码更新版本 :)

    private LiveConnectClient _connection;
    private LiveLoginResult _login;

    public LiveLogin()

    private async void OnLoaded(object sender, RoutedEventArgs routedEventArgs)

            //----------------------------------------------------------------------

            if (_login.Status != LiveConnectSessionStatus.Connected)
            {

            }

            //----------------------------------------------------------------------

            //----------------------------------------------------------------------
            _connection = new LiveConnectClient(_login.Session);
        }
        catch (Exception ex)
