推荐答案

为此您必须创建ViewModel。然后从您的域模型中填充ViewModel数据并将其绑定到您的视图中（即ViewModel查看）。



什么是ViewModel？



＃允许您将一个或多个数据模型或源中的多个实体整形为一个对象



＃优化消费和视图渲染



我写了一篇关于此的文章。请查看更多信息。



如何在ASP.NET MVC中使用ViewModel？

For that you have to create ViewModel.Then fill that ViewModel from your domain models data and bind that into your view (i.e. ViewModel to View).

What is a ViewModel ?

# Allow you to shape multiple entities from one or more data models or sources into a single object

# Optimized for consumption and rendering by the view

I have written an article about this.Please check that for more info.
