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










　　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 ，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

















　　Account/AccountPicture.xaml.cs



/*
* 演示如何获取或设置微软账号的图片和视频
*/
using System;
using Windows.Storage;
using Windows.Storage.Pickers;
using Windows.Storage.Streams;
using Windows.System.UserProfile;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media.Imaging;
using Windows.UI.Xaml.Navigation;
using XamlDemo.Common;
namespace XamlDemo.Account
{
public sealed partial class AccountPicture : Page
{
public AccountPicture()
{
this.InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
GetSmallImage();
GetLargeImage();
GetVideo();
// 当微软账号的图片或视频发生变化时触发的事件
UserInformation.AccountPictureChanged += PictureChanged;
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
UserInformation.AccountPictureChanged -= PictureChanged;
}
private void PictureChanged(object sender, object e)
{
GetSmallImage();
GetLargeImage();
GetVideo();
}
// 获取小图片
private async void GetSmallImage()
{
// UserInformation.GetAccountPicture(AccountPictureKind.SmallImage) - 获取当前微软账号的小图片
StorageFile image = UserInformation.GetAccountPicture(AccountPictureKind.SmallImage) as StorageFile;
if (image != null)
{
try
{
IRandomAccessStream imageStream = await image.OpenReadAsync();
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(imageStream);
imgSmall.Source = bitmapImage;
}
finally { }
}
}
// 获取大图片
private async void GetLargeImage()
{
// UserInformation.GetAccountPicture(AccountPictureKind.LargeImage) - 获取当前微软账号的大图片
StorageFile image = UserInformation.GetAccountPicture(AccountPictureKind.LargeImage) as StorageFile;
if (image != null)
{
try
{
IRandomAccessStream imageStream = await image.OpenReadAsync();
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(imageStream);
imgLarge.Source = bitmapImage;
}
finally { }
}
}
// 获取视频
private async void GetVideo()
{
// UserInformation.GetAccountPicture(AccountPictureKind.Video) - 获取当前微软账号的视频
StorageFile video = UserInformation.GetAccountPicture(AccountPictureKind.Video) as StorageFile;
if (video != null)
{
try
{
IRandomAccessStream videoStream = await video.OpenAsync(FileAccessMode.Read);
mediaElement.SetSource(videoStream, "video/mp4");
}
finally { }
}
}

// 设置图片
private async void btnSetImage_Click_1(object sender, RoutedEventArgs e)
{
if (Helper.EnsureUnsnapped())
{
FileOpenPicker imagePicker = new FileOpenPicker
{
ViewMode = PickerViewMode.Thumbnail,
SuggestedStartLocation = PickerLocationId.PicturesLibrary,
FileTypeFilter = { ".jpg", ".jpeg", ".png", ".bmp" }
};
StorageFile imageFile = await imagePicker.PickSingleFileAsync();
if (imageFile != null)
{
// UserInformation.SetAccountPicturesAsync() - 设置微软账号的图片和视频（可以分别指定：小图片，大图片，视频）
SetAccountPictureResult result = await UserInformation.SetAccountPicturesAsync(null, imageFile, null);
if (result == SetAccountPictureResult.Success)
{
}
}
}
}
}
}
　　
3、演示微软账号的验证，和相关信息的获取
Account/AccountAuthorization.xaml












　　Account/AccountAuthorization.xaml.cs



/*
* 演示微软账号的验证，和相关信息的获取
*
* 注：
* 1、如果要使用此功能，需要先去 https://manage.dev.live.com/Applications/Index 注册，否则会出现“应用程序请求身份验证令牌被禁用或者配置错误”错误
* 2、关于 Live Connect 的更多东西，请参见“Live Connect 开发人员中心”：http://msdn.microsoft.com/zh-cn/live

using System;
using System.Collections.Generic;

using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

{
public sealed partial class AccountAuthorization : Page

/*

if (result.Tickets[0].Value != string.Empty)

lblMsg.Text += "token: " + result.Tickets[0].Value;
lblMsg.Text += Environment.NewLine;
}
else

}
catch (Exception ex)
