The ForEachSMOEnumerator object is created and hosted by a ForEachEnumeratorHost. The following code example shows how to create a ForEachSMOEnumerator within the host object.

            ForEachEnumeratorInfos infos = app.ForEachEnumeratorInfos;
            ForEachEnumeratorInfo info = null;

            foreach (ForEachEnumeratorInfo enumInfo in infos)
            {
            Console.Write("Available enumerators: {0}\n", enumInfo.Name);
            // When the SMO enumerator is found, set the info variable.

            {
