Add new records to private Outlook distribution list

I need to read records containing name and email from a file or database and add them to an existing Oulook distribution list (from the private contacts, not from the GAL).

I just saw examples of reading from OL using LINQ to DASL which I have working for mail and appointments, but I can't figure out how to list the contents of a dist list:

private static void GetContacts() { Outlook.Application app = new Outlook.Application(); Outlook.Folder folder = (Outlook.Folder)app.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts); var distLists = from item in folder.Items.AsQueryable<MyDistList>() where item.DLName == "My Dist List" select item.Item; var builder = new StringBuilder(); foreach (var list in distLists) { builder.AppendLine(list.DLName); foreach (var item in list.Members) { // can't figure out how to iterate through the members here // compiler says Object doesn't have GeNumerator... } } Console.WriteLine(builder.ToString()); Console.ReadLine(); }

Once I can read the members I need to be able to add new ones which is even more trick. Any help would be appreciated.


Turns out it is easy enough. I was simply missing the call to Resolve as I thought that was only if you were resolving against the GAL:

Outlook.Recipient rcp = app.Session.CreateRecipient("Smith, John<>"); rcp.Resolve(); list.AddMember(rcp); list.Save();

And I can create an iterator that uses the distList.GetMember method:

// Wrap DistListItem.GetMembers() as an iterator

public static class DistListItemExtensions { public static IEnumerable<Outlook.Recipient> Recipients(this Outlook.DistListItem distributionList) { for (int i = 1; i <= distributionList.MemberCount; i++) { yield return distributionList.GetMember(i); } } }
