Like this ?

The below code I copied from here

Preventing AutoCAD objects from being selected


 void OnSelectionAdded(object sender, SelectionAddedEventArgs e)
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Editor ed = doc.Editor;

            ObjectId[] addedIds = e.AddedObjects.GetObjectIds();

            for (int i = 0; i < addedIds.Length; i++)

                ObjectId oid = addedIds[i];

                ed.WriteMessage("Selected Item : " +(oid.ObjectClass.DxfName));
