背水一战 Windows 10 (82) - 用户和账号: 获取用户的信息, 获取用户的同意

作者：webabcd

介绍
背水一战 Windows 10 之 用户和账号

• 获取用户的信息
• 获取用户的同意

示例
1、演示如何获取用户的信息
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

/*
 * 演示如何获取用户的信息
 *
 * 需要在 Package.appxmanifest 中的“功能”中勾选“用户账户信息”，即 <Capability Name="userAccountInformation" />
 * 如上配置之后，即可通过 api 获取用户的相关信息（系统会自动弹出权限请求对话框）
 *
 * User - 用户
 *     FindAllAsync() - 查找全部用户，也可以根据 UserType 和 UserAuthenticationStatus 来查找用户
 *         经过测试，其只能返回当前登录用户
 *     GetPropertyAsync(), GetPropertiesAsync() - 获取用户的指定属性
 *         可获取的属性请参见 Windows.System.KnownUserProperties
 *     GetPictureAsync() - 获取用户图片
 *         图片规格有 64x64, 208x208, 424x424, 1080x1080
 *     NonRoamableId - 用户 id
 *         此 id 不可漫游
 *     UserType - 用户类型
 *         LocalUser, RemoteUser, LocalGuest, RemoteGuest
 *     UserAuthenticationStatus - 用户的身份验证状态
 *         Unauthenticated, LocallyAuthenticated, RemotelyAuthenticated
 *     CreateWatcher() - 返回 UserWatcher 对象，用于监听用户的状态变化
 *         本例不做演示

                    IRandomAccessStream stream = await streamReference.OpenReadAsync();
                    BitmapImage bitmapImage = new BitmapImage();
                    bitmapImage.SetSource(stream);
                    imageProfile.Source = bitmapImage;
                }
            }

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

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

            <Button Name="buttonRequestConsent" Content="获取用户的同意" Click="buttonRequestConsent_Click" Margin="5" />

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

UserAndAccount/UserVerifier.xaml.cs

/*
 * 演示如何获取用户的同意
 *
 * UserConsentVerifier - 验证器（比如 pin 验证等）
 *     CheckAvailabilityAsync() - 验证器的可用性
 *     RequestVerificationAsync(string message) - 请求用户的同意（可以指定用于提示用户的信息）
