How to Active Directory User Properties with System.DirectoryServices.AccountManagement Namespace?

To retrieve Active Directory user properties using the System.DirectoryServices.AccountManagement namespace in C#, you can use the UserPrincipal class.

Here's an example of how to retrieve user properties using the UserPrincipal class:

using System.DirectoryServices.AccountManagement; // Set up the context for the Active Directory domain using (var context = new PrincipalContext(ContextType.Domain, "domain.com")) { // Search for a user by username var user = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, "username"); if (user != null) { // Retrieve the user properties var firstName = user.GivenName; var lastName = user.Surname; var email = user.EmailAddress; var phoneNumber = user.VoiceTelephoneNumber; var department = user.Department; } }

In this example, we first set up a PrincipalContext object to represent the Active Directory domain. We then call the UserPrincipal.FindByIdentity method to retrieve a UserPrincipal object representing the user with the specified username.

We then retrieve the user properties using the properties of the UserPrincipal object, such as GivenName, Surname, EmailAddress, VoiceTelephoneNumber, and Department.

By using the UserPrincipal class, you can easily retrieve Active Directory user properties in your C# application. Note that you can also modify user properties using the UserPrincipal class, by setting the properties and calling the Save method of the UserPrincipal object.
