请在控制器中完成模型绑定的实现,要求绑定不成功或者出现错误时,抛出异常。代码如下: public ActionResult Edit() { var album=new Album(); (album);//绑定模型Album if( )//判断是否绑 { db.Entry( ).State=EntityState.Modified; db.SaveChange(); return RedirecToAction("Index"); } else { ViewBag.GenreId=new SelectList(db.Genres,"GenreId","Name",album.GenreId); ViewBag.ArtistId=new SelectList(db.Artists,"ArtistId","Name",album.ArtistId); } } 请将以下选项正确地填入各下划线处: A.album B.TryUpdateModel C.UpdateModel D.ModelState.IsValid E.Album F.Albums
