微軟賬號的驗證，和相關信息的獲取

示例

1、演示如何獲取微軟賬號的用戶相關的信息

Account/AccountInfo.xaml

<Page
    x:Class="XamlDemo.Account.AccountInfo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:XamlDemo.Account"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">
    
    <Grid Background="Transparent">
        <StackPanel Margin="120 0 0 0">
    
            <TextBlock Name="lblMsg" FontSize="14.667" />
    
        </StackPanel>
    </Grid>
</Page>

Account/AccountInfo.xaml.cs

/*

 */
    
using System;
using Windows.System.UserProfile;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Navigation;
    
namespace XamlDemo.Account
{
    public sealed partial class AccountInfo : Page
    {
        public AccountInfo()
        {
            this.InitializeComponent();
        }
    
        protected async override void OnNavigatedTo(NavigationEventArgs e)
        {
            if (UserInformation.NameAccessAllowed) // 是否允許訪問用戶名
            {
                // 獲取用於顯示的名稱
                lblMsg.Text = "display name: " + await UserInformation.GetDisplayNameAsync();
                lblMsg.Text += Environment.NewLine;
    
                // 獲取 first name
                lblMsg.Text += "first name: " + await UserInformation.GetFirstNameAsync();
                lblMsg.Text += Environment.NewLine;

                lblMsg.Text += "last name: " + await UserInformation.GetLastNameAsync();
                lblMsg.Text += Environment.NewLine;
            }
    
            // 如果需要獲取 GetDomainNameAsync(), GetPrincipalNameAsync(), GetSessionInitiationProtocolUriAsync() 等信息
            // 則需要在 Package.appxmanifest 中增加配置 <Capability Name="enterpriseAuthentication" />，且必須使用公司賬號上傳 app
        }
    }
}

2、演示如何獲取或設置微軟賬號的圖片和視頻

    <Grid Background="Transparent">
        <StackPanel Margin="120 0 0 0">
    
            <StackPanel Orientation="Horizontal">
                <Button x:Name="btnSetImage" Content="設置當前微軟賬號的圖片（可以分別指定小圖，大圖，視頻）" Click="btnSetImage_Click_1" />
            </StackPanel>
    
            <StackPanel Orientation="Horizontal" Margin="0 10 0 0">
                <Image x:Name="imgSmall" Width="96" Height="96" HorizontalAlignment="Left" />
                <Image x:Name="imgLarge" Width="448" Height="448" Margin="10 0 0 0" HorizontalAlignment="Left" />
                <MediaElement x:Name="mediaElement" Width="200" Height="200" Margin="10 0 0 0" HorizontalAlignment="Left" />
