Get Outlook AddressBook Contacts folders in VSTO addIn

Question

Am developing an Outlook VSTO AddIn wherein I need to get the list of folders inside the AddressBook using C# code (see below screenshot)

That is, here I need to get the list folder names and subfolder names like Contacts, Offline Global Address List, All Contacts, All Distribution Lists, etc.

i.e., the folders we get using Outlook.SelectNamesDialog snd =
Application. Session.GetSelectNamesDialog();
snd.Display();

Note that now I have two accounts configured within my Outlook.

Thanks in advance!
