推荐答案

使用PrincipalContext和UserPrincipal类。 MSDN足以让你完成它。



主要内容类（System.DirectoryServices.AccountManagement） [ ^ ]



UserPrincipal Class（System.DirectoryServices） .AccountManagement） [ ^ ]



问候

Hi,

By using the PrincipalContext and UserPrincipal classes. The MSDN holds enough for you to be able to get it done.

PrincipalContext Class (System.DirectoryServices.AccountManagement)[^]

UserPrincipal Class (System.DirectoryServices.AccountManagement)[^]

Regards

看看： 查询AD并获取LastLogonTimeStamp [ ^ ]

Take a look: Query AD and get LastLogonTimeStamp[^]

Dim SearchContext As New PrincipalContext(System.DirectoryServices.AccountManagement.ContextType.Domain, <DomainName>)
 Dim ADUser As New UserPrincipal(SearchContext)
 Dim ADSearcher As New PrincipalSearcher()
 Dim LastLogonDateTimeUTC As DateTime

 ADUser.Name = "*"
 ADSearcher.QueryFilter = ADUser
 Dim SearchResult As PrincipalSearchResult(Of Principal) = ADSearcher.FindAll()
 For Each User As UserPrincipal In SearchResult
  Console.WriteLine("Name: " & User.Name)
  If User.LastLogon.HasValue Then
   LastLogonDateTimeUTC = User.LastLogon
   Console.WriteLine("Last Logon: " & LastLogonDateTimeUTC.ToLocalTime)
  End If
 Next User

如果您正在谈论Windows登录和注销，这将比您想象的要困难得多。



只要用户登录Windows或使用需要身份验证的共享资源（例如将驱动器映射到共享，打开UNC或将内容打印到Windows托管的共享），就会发生登录打印机。这些可以由网络上的任何域控制器进行身份验证，具体取决于具体情况。



Windows默认情况下不会跟踪注销，除非您查看安全日志在用户注销的工作站上。没有跟踪注销的中央存储库。

If you're talking about Windows logins and logouts, this is going to be much harder than you think.

A login occurs whenever a user either logs into Windows or uses a shared resource that requires authentication, like mapping a drive to a share, opening up a UNC, or printing something to a Windows-hosted shared printer. These can be authenticated by any domain controller on the network, depending on circumstances.

Windows, by default, doesn't track logouts, unless you look at the security log on the workstation the user logged out of. There is no central repository that tracks logouts.
