How do I get address lists (NOT global) using Exchange WebServices in C#

问题

the web shows dozens of examples to query the exchange's global address list but i want to query the specific address lists! So every user in our Enterprise is ofcourse listed in our global address list but i want to query the address list of a specific company within our Enterprise.

In the example below, Aswebo, Cosimco, etc.. are address lists.

1. How do I list these address lists?
2. How do I list the people within these address lists?

I don't have exchange setup to test this code, so it will need modifications but it should give you a starting point to explore.

The idea is that you set the ItemView to the ContactSchema to retrieve results by company.

// Get the number of items in the Contacts folder. To keep the response smaller, request only the TotalCount property.
ContactsFolder contactsfolder = ContactsFolder.Bind(service,
                                                    WellKnownFolderName.Contacts,
                                                    new PropertySet(BasePropertySet.IdOnly, FolderSchema.TotalCount));

// Set the number of items to the smaller of the number of items in the Contacts folder or 1000.
int numItems = contactsfolder.TotalCount < 1000 ? contactsfolder.TotalCount : 1000;

// Instantiate the item view with the number of items to retrieve from the Contacts folder.
ItemView view = new ItemView(numItems);

view.PropertySet = new PropertySet(ContactSchema.CompanyName, ContactSchema.EmailAddress1);

// Retrieve the items in the Contacts folder that have the properties you've selected.
FindItemsResults<Item> contactItems = service.FindItems(WellKnownFolderName.Contacts, view);

foreach(var contact in contactItems)
{

            Contact contact    = item as Contact;
            // Filter / Group by company name
            // contact.Companyname
}

You can also use service.FindItems(WellKnownFolderName, SearchFilter, ViewBase) to provide additional filtering.

See this MSDN blog for a code example.

I've been searching all afternoon and came up with the code below. It works.. but looking dirty. I would like an entire Principal approach but it seems I'm too dumb :-)

Anyone that wants to translate this code to 100% 'System.DirectoryServices.AccountManagement'?

using System;
using System.Collections.Generic;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            DirectoryEntry ldap;
            DirectorySearcher ldap_search;
            SearchResultCollection ldap_results;
            PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

            var addressLists = new Dictionary<string, string>();


            // Flexible way (but visually complex!) for building the path LDAP://CN=All Address Lists,CN=Address Lists Container,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=DOMAIN,DC=local
            ldap = new DirectoryEntry("LDAP://RootDSE");
            ldap_search = new DirectorySearcher(new DirectoryEntry("LDAP://CN=Microsoft Exchange, CN=Services," + ldap.Properties["configurationNamingContext"].Value), "(objectClass=msExchOrganizationContainer)");
            ldap_search = new DirectorySearcher(new DirectoryEntry("LDAP://CN=All Address Lists,CN=Address Lists Container," + ldap_search.FindOne().Properties["distinguishedName"][0]), "(objectClass=addressBookContainer)");
            ldap_search.Sort = new SortOption("name", SortDirection.Ascending);

            // Find All Address Lists alphabetically and put these into a dictionary
            ldap_results = ldap_search.FindAll();
            foreach (SearchResult ldap_result in ldap_results)
            {
                var addressList = new DirectoryEntry(ldap_result.Path);
                addressLists.Add(addressList.Properties["name"].Value.ToString(), addressList.Properties["distinguishedName"][0].ToString());
            }

            //// list Address Lists
            //foreach (var addressList in addressLists) Console.WriteLine(addressList.Key);

            // List all users from Address List "Aswebo"
            ldap = new DirectoryEntry("LDAP://" + ldap.Properties["defaultNamingContext"].Value); // rename ldap to LDAP://DC=DOMAIN,DC=local
            ldap_search = new DirectorySearcher(ldap, string.Format("(&(objectClass=User)(showInAddressBook={0}))", addressLists["Aswebo"])); // Search all users mentioned within the specified address list
            ldap_results = ldap_search.FindAll();
            foreach (SearchResult ldap_result in ldap_results)
            {
                // Fetch user properties using the newer interface.. just coz it's nice :-)
                var User = UserPrincipal.FindByIdentity(ctx, IdentityType.DistinguishedName, ldap_result.Path.Replace("LDAP://", ""));
                Console.WriteLine(User.DisplayName);
            }

            Console.ReadLine();
        }
    }
}
