    Unhappy This was a question for an MCTS exam

    You need to retrieve all queued e-mail messages into a collection and ensure type safety. Which code segment should you use to define the signature of the GetQueuedEmailsFromDb() method in the Poller.cs file?

    A. private static object[] GetQueuedEmailsFromDb(int queueID)
    B. private static ArrayList GetQueuedEmailsFromDb(int queueID)
    C. private static EmailMessages GetQueuedEmailsFromDb(int queueID)
    D. private static IList<object> GetQueuedEmailsFromDb(int queueID)

    Is the answer choice D correct since it has generics parameter ?

    It sounds as if the only "type safe collection" there is the " EmailMessages" , thus answer should be C
    ...at present time, using mainly Net 4.0, Vs 2010
