        {
            Application app = new Application();
            ForEachEnumeratorInfos feInfos = app.ForEachEnumeratorInfos;

            // Search the collection by name.
            if (feInfos.Contains("For Each File Enumerator"))
                Console.WriteLine("The collection contains {0} enumerator", feInfos[0].Name);
