如何从员工的UserPrincipal对象获取管理器的UserPrincipal对象

Question

I have an Active Directory searcher to get users' details using UserPrincipal objects. I'm using System.DirectoryServices and System.DirectoryServices.AccountManagement and it's accessing AD through a context.

However, I also need to get the user's manager as a separate UserPrincipal object. What would be the most direct way to go about this?

I have tried the following but unfortunately the cast won't work:

DirectoryEntry directoryEntry = (DirectoryEntry)userPrincipal.GetUnderlyingObject();
UserPrincipal manager = (UserPrincipal)directoryEntry.Properties["manager"][0];

I hoped there would be a UserPrincipal property called UsersManager inside every UserPrincipal object but I'm unable to find this so I'm guessing there's no such thing.

Thanks!

The manager attribute will give you the distinguished name of the manager's account, which is just a string. So you'll have to look up the manager's account using that DN.

This might work (assuming you already have a context object):

UserPrincipal manager = UserPrincipal.FindByIdentity(context, IdentityType.DistinguishedName, directoryEntry.Properties["manager"][0].ToString());
