Try this code, wriiten in a hurry, so check on possible errors:

        [CommandMethod("ltname")]
        public void LayoutNameOfBlockRef()
        {
            Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;
            Editor ed = doc.Editor;
         Transaction tr = doc.TransactionManager.StartTransaction();

         using (tr)
         {

             PromptEntityOptions peo = new PromptEntityOptions("\nSelect block >>");
             peo.SetRejectMessage("\nSelect block only >>");
             peo.AddAllowedClass(typeof(BlockReference), false);
             PromptEntityResult res;
             res = ed.GetEntity(peo);
             if (res.Status != PromptStatus.OK)
                 return;
             Entity ent = (Entity)tr.GetObject(res.ObjectId, OpenMode.ForRead);
             if (ent == null)
                 return;
             BlockReference br = (BlockReference)ent as BlockReference;
             DBObject obj = tr.GetObject(br.OwnerId, OpenMode.ForRead);
             BlockTableRecord lbtr = tr.GetObject(br.OwnerId, OpenMode.ForRead) as BlockTableRecord;
             ObjectId ltId = lbtr.LayoutId;
             Layout lt = tr.GetObject(ltId, OpenMode.ForRead) as Layout;
             Autodesk.AutoCAD.ApplicationServices.Application.ShowAlertDialog("BlockReference belongs to tab: " + lt.LayoutName);
             tr.Commit();
         }
    }
