重新想象 Windows 8 Store Apps (58) - 微软账号

作者：webabcd


介绍
重新想象 Windows 8 Store Apps 之 微软账号

• 获取微软账号的用户相关的信息
• 获取或设置微软账号的图片和视频
• 微软账号的验证，和相关信息的获取

示例
1、演示如何获取微软账号的用户相关的信息
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

/*
 * 演示如何获取微软账号的用户相关的信息
 */

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) // 是否允许访问用户名
            {
                // 获取用于显示的名称
                lblMsg.Text = "display name: " + await UserInformation.GetDisplayNameAsync();
                lblMsg.Text += Environment.NewLine;

                // 获取 first name
                lblMsg.Text += "first name: " + await UserInformation.GetFirstNameAsync();
                lblMsg.Text += Environment.NewLine;

                // 获取 last name
                lblMsg.Text += "last name: " + await UserInformation.GetLastNameAsync();
                lblMsg.Text += Environment.NewLine;
            }

            // 如果需要获取 GetDomainNameAsync(), GetPrincipalNameAsync(), GetSessionInitiationProtocolUriAsync() 等信息
            // 则需要在 Package.appxmanifest 中增加配置 <Capability Name="enterpriseAuthentication" />，且必须使用公司账号上传 app
        }
    }
}

2、演示如何获取或设置微软账号的图片和视频
Account/AccountPicture.xaml

<Page
    x:Class="XamlDemo.Account.AccountPicture"
    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">

            <StackPanel Orientation="Horizontal">
                <Button x:Name="btnSetImage" Content="设置当前微软账号的图片（可以分别指定小图，大图，视频）" 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" />
            </StackPanel>

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

Account/AccountPicture.xaml.cs

/*

                    BitmapImage bitmapImage = new BitmapImage();

                }
                finally { }
            }
        }

        // 获取视频

                }
                finally { }
            }
        }


        // 设置图片
        private async void btnSetImage_Click_1(object sender, RoutedEventArgs e)
        {

                }
            }

3、演示微软账号的验证，和相关信息的获取
Account/AccountAuthorization.xaml

<Page

    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" />
            <Button Name="btnSignIn" Content="登录"  Margin="0 10 0 0" Click="btnSignIn_Click_1" />
            <Button Name="btnSignOut" Content="注销" Margin="0 10 0 0" Click="btnSignOut_Click_1" />
            
        </StackPanel>
    </Grid>
</Page>

Account/AccountAuthorization.xaml.cs

/*
