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

using System.Collections.Generic;
using Windows.Foundation.Collections;
using Windows.Storage.Streams;
using Windows.System;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media.Imaging;
using Windows.UI.Xaml.Navigation; namespace Windows10.UserAndAccount
{
public sealed partial class UserInfo : Page
{
public UserInfo()
{
this.InitializeComponent();
} protected async override void OnNavigatedTo(NavigationEventArgs e)
{
base.OnNavigatedTo(e); // 我这里测试的结果是：返回的集合中只有一个元素，就是当前的登录用户
IReadOnlyList<User> users = await User.FindAllAsync(); // 系统会自动弹出权限请求对话框
User user = users?[];
if (user != null)
{
// 对于获取用户的 NonRoamableId, Type, AuthenticationStatus 信息，不同意权限请求也是可以的
string result = "NonRoamableId: " + user.NonRoamableId + "\n";
result += "Type: " + user.Type.ToString() + "\n";
result += "AuthenticationStatus: " + user.AuthenticationStatus.ToString() + "\n"; // 对于获取用户的如下信息及图片，则必须要同意权限请求
string[] desiredProperties = new string[]
{
KnownUserProperties.DisplayName,
KnownUserProperties.FirstName,
KnownUserProperties.LastName,
KnownUserProperties.ProviderName,
KnownUserProperties.AccountName,
KnownUserProperties.GuestHost,
KnownUserProperties.PrincipalName,
KnownUserProperties.DomainName,
KnownUserProperties.SessionInitiationProtocolUri,
};
// 获取用户的指定属性集合
IPropertySet values = await user.GetPropertiesAsync(desiredProperties);
foreach (string property in desiredProperties)
{
result += property + ": " + values[property] + "\n";
}
// 获取用户的指定属性
// object displayName = await user.GetPropertyAsync(KnownUserProperties.DisplayName); lblMsg.Text = result; // 获取用户的图片
IRandomAccessStreamReference streamReference = await user.GetPictureAsync(UserPictureSize.Size64x64);
if (streamReference != null)
{
IRandomAccessStream stream = await streamReference.OpenReadAsync();
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(stream);
imageProfile.Source = bitmapImage;
}
}
}
}
}
2、演示如何获取用户的同意
UserAndAccount/UserVerifier.xaml
<Page
x:Class="Windows10.UserAndAccount.UserVerifier"
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" /> <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）
*/ using System;
using Windows.Security.Credentials.UI;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Navigation; namespace Windows10.UserAndAccount
{
public sealed partial class UserVerifier : Page
{
public UserVerifier()
{
this.InitializeComponent();
} protected async override void OnNavigatedTo(NavigationEventArgs e)
{
base.OnNavigatedTo(e); try
{
UserConsentVerifierAvailability verifierAvailability = await UserConsentVerifier.CheckAvailabilityAsync();
switch (verifierAvailability)
{
case UserConsentVerifierAvailability.Available: // 验证器可用
lblMsg.Text = "UserConsentVerifierAvailability.Available";
break;
case UserConsentVerifierAvailability.DeviceBusy:
lblMsg.Text = "UserConsentVerifierAvailability.DeviceBusy";
break;
case UserConsentVerifierAvailability.DeviceNotPresent:
lblMsg.Text = "UserConsentVerifierAvailability.DeviceNotPresent";
break;
case UserConsentVerifierAvailability.DisabledByPolicy:
lblMsg.Text = "UserConsentVerifierAvailability.DisabledByPolicy";
break;
case UserConsentVerifierAvailability.NotConfiguredForUser:
lblMsg.Text = "UserConsentVerifierAvailability.NotConfiguredForUser";
break;
default:
break;
}
}
catch (Exception ex)
{
lblMsg.Text = ex.ToString();
} lblMsg.Text += "\n";
} private async void buttonRequestConsent_Click(object sender, RoutedEventArgs e)
{
try
{
UserConsentVerificationResult consentResult = await UserConsentVerifier.RequestVerificationAsync("我要做一些操作，您同意吗？");
switch (consentResult)
{
case UserConsentVerificationResult.Verified: // 验证通过
lblMsg.Text += "UserConsentVerificationResult.Verified";
break;
case UserConsentVerificationResult.DeviceBusy:
lblMsg.Text += "UserConsentVerificationResult.DeviceBusy";
break;
case UserConsentVerificationResult.DeviceNotPresent:
lblMsg.Text += "UserConsentVerificationResult.DeviceNotPresent";
break;
case UserConsentVerificationResult.DisabledByPolicy:
lblMsg.Text += "UserConsentVerificationResult.DisabledByPolicy";
break;
case UserConsentVerificationResult.NotConfiguredForUser:
lblMsg.Text += "UserConsentVerificationResult.NotConfiguredForUser";
break;
case UserConsentVerificationResult.RetriesExhausted:
lblMsg.Text += "UserConsentVerificationResult.RetriesExhausted";
break;
case UserConsentVerificationResult.Canceled: // 验证取消
lblMsg.Text += "UserConsentVerificationResult.Canceled";
break;
default:
break;
}
}
catch (Exception ex)
{
lblMsg.Text += ex.ToString();
} lblMsg.Text += "\n";
}
}
}
OK
