我试图从我的索引中传递一个额外的值，并且我已经从返回中传递了一些其他的东西，因为我使用的是 pagedList 方法。我需要将 vm 从索引返回中传递出来，所以它看起来像
return View(vm);
目前看起来像这样
return View(IAMP.ToPagedList(pageNumber, pageSize));
我一直在阅读下面链接的这个问题，以更好地了解如何将两个表传递给一个视图，但我无法弄清楚我应该如何使用 pagedList 所需的当前返回值返回“vm”。我还发布了我的控制器、模型和索引的代码，如果需要更多代码以提高清晰度，请告诉我。
真正的问题是我需要获得一个版本号以显示在索引中以及位于另一个表中的其他值。我希望我正在尝试做的事情是有意义的。:) 感谢您对所有可以提供帮助的人的支持！
