它的替代品是什么?

what is the alternate for it?

您应该只使用 ViewModels，它是推荐的方法.创建强类型视图.这将使您的代码更简洁且易于维护.

You should only use ViewModels, It's the recommended approach. Create Strongly typed views. It would make your code cleaner and easy to maintain.

会出现哪些极端问题?

Viewbags/ViewData 的问题是编译时检查.ViewBags 只是字典，直到运行时您才会意识到任何问题，因此它会使您的代码容易出错.所以总是尝试使用 ViewModel.

Issue with Viewbags/ViewData is compile time checking. ViewBags are just dictionaries and you won't be aware about any issues until run time and thus it makes your code error-prone. So always try to go with ViewModels.
