我们可以在视图中拥有多个模型吗？ [英] Can we have multiple models in a view ?

问题描述

我知道可以通过将一个List属性保存到另一个中来完成，如下所示：

 Class Customer 
 {
  public   string 名称{ get < /跨度>;  set ;} 
公开列表<地址>地址{获取;  set ;} 
 
} 
 
类地址
 {
  public   string  StreetNo { get ;  set ;} 
  public   string  HouseNo { get ;  set ;} 
} 

然后，@ model View中的Customer和@ Model.Name和@foreach（地址中的var项目）{item.StreetNo}来呈现值或保留ViewModel或ModelBinder。



但是我的具体问题是如果我在下面的视图中保持如下，



@model客户

@model地址

- 在Customer =>以下模型类的Index.cshtml。

 Class Customer 
 {
  public   string 名称{ get ;  set ;} 
 
} 
 
类地址
 {
  public   string  StreetNo { get ;  set ;} 
  public   string  HouseNo { get ;  set ;} 
} 

无效。为什么？



在这种情况下，相同的视图应该呈现两个不同的模型对象和我的CustomerController => Action方法（）我将根据条件（if / else）返回Customer或Address对象。我不想使用局部视图。



具体问题是为什么我们在视图中不能有两个模型？ MVC内部如何停止这样做/不接受这样做？



任何指导都是适合的。

ASP.NET MVC 4 / MVC 5视图中的多个模型 [ ^ ]

如何选择在ASP.NET MVC中传递多个模型的最佳方式 [ ^ ]

I know that it can be done by keeping one List property into another, Like Below:

Class Customer
{
 public string Name {get; set;}
 Public List<Address> Address {get; set;}

}

Class Address
{
 public string StreetNo {get; set;}
 public string HouseNo {get; set;}
}

And then, @model Customer in View and @Model.Name and @foreach(var item in Address){item.StreetNo} to render values or keeping a ViewModel or ModelBinder.

But my specific question is if I keep like below in a view,

@model Customer
@model Address
-- in Customer => Index.cshtml for the below model classes.

Class Customer
{
 public string Name {get; set;}

}

Class Address
{
 public string StreetNo {get; set;}
 public string HouseNo {get; set;}
}

Will not work. Why ?

In this case, the same view should render for two different model objects and in my CustomerController => Action method() I will either return Customer or an Address object based on condition(if/else). I do not want to use partial view.

The specific question is Why we can not have two models in a View ? How MVC internally stops to do this/not accept to do this ?

Any guidence would be appriciable.
