You have to access the corresponding dictionary from the NOD and iterate through its content.

For example here is how to access the attached PDF dictionary and reload the pdfs:

 [CommandMethod("PdfNetReload")]
        static public void PdfNetReload()
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database db = doc.Database;
            Editor ed = doc.Editor;

            using (Transaction Tx = db.TransactionManager.StartTransaction())
            {
                DBDictionary nod = Tx.GetObject(db.NamedObjectsDictionaryId, OpenMode.ForRead) as DBDictionary;

                string defDictKey = UnderlayDefinition.GetDictionaryKey(typeof(PdfDefinition));

                if (!nod.Contains(defDictKey))
                    return;

                DBDictionary pdfDict = Tx.GetObject(nod.GetAt(defDictKey), OpenMode.ForWrite) as DBDictionary;

                foreach (DBDictionaryEntry entry in pdfDict)
                {
                    PdfDefinition entryObj = Tx.GetObject(entry.Value, OpenMode.ForWrite) as PdfDefinition;
                    entryObj.Load(null);

                    ObjectIdCollection collection = entryObj.GetPersistentReactorIds();

                    foreach (ObjectId id in collection)
                    {
                        DBObject temObject = Tx.GetObject(id, OpenMode.ForRead);

                        if (temObject is PdfReference)
                        {
                            PdfReference pdfref = temObject as PdfReference;
                            pdfref.UpgradeOpen();
                            pdfref.RecordGraphicsModified(true);
                        }
                    }
                }

                Tx.Commit();
            }
        }
