Question

I want do get Active Directory Properties from a user and I want to use System.DirectoryServices.AccountManagement.

my code:

public static void GetUserProperties(string dc,string user) 
        {
            PrincipalContext ctx = new PrincipalContext(ContextType.Domain, dc);
            UserPrincipal u = UserPrincipal.FindByIdentity(ctx, user);

            string firstname = u.GivenName;
            string lastname = u.Surname;
            string email = u.EmailAddress;
            string telephone = u.VoiceTelephoneNumber;

            ...//how I can get company and other properties?
        }

Solution 1

You can transition into the DirectoryServices namespace to get any property you need.

PrincipalContext ctx = new PrincipalContext(ContextType.Domain, dc);
UserPrincipal u = UserPrincipal.FindByIdentity(ctx, user);

string firstname = u.GivenName;
string lastname = u.Surname;
string email = u.EmailAddress;
string telephone = u.VoiceTelephoneNumber;
string company = String.Empty;

...//how I can get company and other properties?
if (userPrincipal.GetUnderlyingObjectType() == typeof(DirectoryEntry))
{
    // Transition to directory entry to get other properties
    using (var entry = (DirectoryEntry)userPrincipal.GetUnderlyingObject())
    {
        if (entry.Properties["company"] != null)
            company = entry.Properties["company"].Value.ToString();
    }
}

If you want to change the proppertie dont forget to call userPrincipal.save() after you changed the value.

entry.Properties["company"].value = company;
userPrincipal.save();
