PrincipalContext＆amp; UserPrincipal如何知道密码何时到期？

Question

我有一个具有很多属性的UserPrincipal对象，但我找不到密码到期日期的属性。

如何做到这一点？

Answer 1

这是我能够提出的最简单的方法......

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：<{>>添加参考对话框的 COM 标签上列出ActiveDs Active DS类型库

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