c# - PrincipalContext & UserPrincipal 如何知道密码何时过期？

Question

我有一个包含很多属性的 UserPrincipal 对象，但我找不到密码过期日期的属性。

如何做到这一点？

Answer 1

这是我能想到的最简单的方法...

using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;
using ActiveDs;

//...

PrincipalContext domain = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(domain, "username");
DirectoryEntry entry = (DirectoryEntry)user.GetUnderlyingObject();
IADsUser native = (IADsUser)entry.NativeObject;
Console.WriteLine(user.GivenName + "'s password will expire on " + native.PasswordExpirationDate);

注意 #1:ActiveDs 在 Add Reference 对话框的 COM 选项卡上列为 Active DS Type Library

注意 #2:据我所知，PasswordExpirationDate 是 UTC 时间。
