How to create an iterator based on another collection

I have a collection of Users List where User looks like: User -id -uniqueKey (String)

I have another collection of List where ExternalUser has a uniqueKey also.

I want to loop through the List, but actually return a External User.

How can I create an iterator that does this?

Without having your sample code, it is hard to fully answer. However, this is a code sample that I believe would provide you with what you are looking for:

var externalUsers = users.Select(user => externalUserIds.Contains(user.UniqueKey));

That will provide you with a iterator of user object instances which have a UniqueKey of an external user.
