Backwater world war I Windows 10 (83)-users and accounts: Add and manage data accounts, and verify OAuth 2.0

Author: webabcd


Introduction
Users and accounts of Windows 10

• Add and manage data accounts
• OAuth 2.0 Verification

Example
1. demonstrate how to add and manage data accounts
UserAndAccount/DataAccount. xaml

<Page x: Class = "Windows10.UserAndAccount. dataAccount "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"> <TextBlock Name = "lblMsg" Margin = "5"/> <button Name = "buttonAdd" Content = "add a data account" Margin = "5" Click = "buttonAdd_Click"/> </StackPanel> </Grid> </Page>

UserAndAccount/DataAccount. xaml. cs

/** Demonstrate data account addition and Management ** UserDataAccountManager-data account manager * ShowAddAccountAsync ()-The account addition page * ShowAccountSettingsAsync ()-The Account Management Interface * RequestStoreAsync () is displayed () -Return to the storage region of the current user's data account * GetForUser ()-Return to the storage region of the specified user's data account (use the RequestStoreAsync () method of the returned UserDataAccountManagerForUser object) ** UserDataAccountStore-data account storage Region * FindAccountsAsync ()-returns all data Accounts * GetAccountAsync ()-returns the specified data account ** UserDataAccount-data account * Use RDisplayName-user name * Id-Unique Id of the data account on the local device * SaveAsync ()-save * DeleteAsync ()-delete *... there are many other attributes and Methods ** Note: You need to use the Package function. appxmanifest for related configuration * 1. Windows is used. system. <Capability Name = "userAccountInformation"/> * 2. <Capability Name = "appointments"/>, <Capability Name = "contacts"/> */using System; using System. linq; using System. collections. generic; using Windows. applicationModel.

2. demonstrate how to develop a client based on OAuth 2.0 Verification
