背水一戰 Windows 10 (82) - 用戶和賬號: 獲取用戶的信息, 獲取用戶的同意

作者：webabcd


介紹
背水一戰 Windows 10 之 用戶和賬號

• 獲取用戶的信息
• 獲取用戶的同意

示例
1、演示如何獲取用戶的信息
UserAndAccount/UserInfo.xaml

<Page
    x:Class="Windows10.UserAndAccount.UserInfo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.UserAndAccount"
    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="10 0 10 10">

            <TextBlock Name="lblMsg" Margin="5" />

            <Image x:Name="imageProfile" Margin="5" Width="64" Height="64" HorizontalAlignment="Left" />
            
        </StackPanel>
    </Grid>
</Page>

UserAndAccount/UserInfo.xaml.cs

/*
 * 演示如何獲取用戶的信息
 * 
 * 需要在 Package.appxmanifest 中的“功能”中勾選“用戶賬戶信息”，即 <Capability Name="userAccountInformation" />
 * 如上配置之后，即可通過 api 獲取用戶的相關信息（系統會自動彈出權限請求對話框）
 * 
 * User - 用戶
 *     FindAllAsync() - 查找全部用戶，也可以根據 UserType 和 UserAuthenticationStatus 來查找用戶
 *         經過測試，其只能返回當前登錄用戶
 *     GetPropertyAsync(), GetPropertiesAsync() - 獲取用戶的指定屬性
 *         可獲取的屬性請參見 Windows.System.KnownUserProperties
 *     GetPictureAsync() - 獲取用戶圖片
 *         圖片規格有 64x64, 208x208, 424x424, 1080x1080
 *     NonRoamableId - 用戶 id
 *         此 id 不可漫游
 *     UserType - 用戶類型
 *         LocalUser, RemoteUser, LocalGuest, RemoteGuest
 *     UserAuthenticationStatus - 用戶的身份驗證狀態
 *         Unauthenticated, LocallyAuthenticated, RemotelyAuthenticated
 *     CreateWatcher() - 返回 UserWatcher 對象，用於監聽用戶的狀態變化
 *         本例不做演示

    <Grid Background="Transparent">
        <StackPanel Margin="10 0 10 10">

            <TextBlock Name="lblMsg" Margin="5" />

            <Button Name="buttonRequestConsent" Content="獲取用戶的同意" Click="buttonRequestConsent_Click" Margin="5" />

        </StackPanel>
    </Grid>
</Page>

UserAndAccount/UserVerifier.xaml.cs

/*
 * 演示如何獲取用戶的同意
 * 
 * UserConsentVerifier - 驗證器（比如 pin 驗證等）
 *     CheckAvailabilityAsync() - 驗證器的可用性
 *     RequestVerificationAsync(string message) - 請求用戶的同意（可以指定用於提示用戶的信息）
