使用 C# 代码从 Active Directory 获取当前登录信息

Question

如何使用 C# 代码从 Windows Active Directory 获取当前用户的登录名？

Answer 1

Simply,

string Name = new System.Security.Principal.WindowsPrincipal(System.Security.Principal.WindowsIdentity.GetCurrent()).Identity.Name;

OR

string Name = System.Environment.UserName  

OR

string Name = Environment.GetEnvironmentVariable("USERNAME");

OR

string Name = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

works :)

Answer 2

If you're on .NET 3.5 and up, you can use:

// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// find current user
UserPrincipal user = UserPrincipal.Current;

if(user != null)
{
   string loginName = user.SamAccountName; // or whatever you mean by "login name"
}    

The new S.DS.AM makes it really easy to play around with users and groups in AD!

Answer 3

System.DirectoryServices.AccountManagement.UserPrincipal.Current.Name

This is also working for me! Thanks

Answer 4

我得到了“NT AUTHORITY\\NETWORK SERVICE”以及其他提供的解决方案，但System.Threading.Thread.CurrentPrincipal.Identity.Name.ToString()为我工作。

Answer 5

我有这个想法，非常适合我！
