如何访问在剃刀视图的数据？ [英] How do I access data in a view in Razor?

问题描述

在标准的WebForms，我早就性能屈指可数，并且设置这些。然后，网页会绑定到他们，例如使用＆LT;％＃客户名称％方式＆gt;

In standard WebForms, I would have a handful of properties, and set those. Then the Web Page would bind to them, for example with <%#CustomerName%>.

据我所知，MVC是一种不同的方法，但仍有一定是在同一时间显示来自多个源的数据的基本需要。

I understand that MVC is a different approach, but there must still be a basic need for displaying data from multiple sources at the same time.

我可以看到，如果我用 @Model 然后将访问控制器中的数据集。但是，如果你想从2个或3个独立的项目显示数据是什么？

I can see that if I use @Model then it will access the data set in the controller. But what if You want to display data from 2 or 3 separate items?

如果我想显示客户，他们的地址和当前订单都在同一页上，有没有经过这3个独立的模式，以一个视图的方式，或者是它，我需要为每一个局部视图，然后显示他们都在同一页上的情况？

If I want to display a Customer, their address and their current order all on the same page, is there a way of passing these 3 seperate models to the one view, or is it a case that I need to create a partial view for each, and then display them all on the same page?

推荐答案

有一个视图模型它包含所有这些数据（类）作为属性并返回到您的视图

Have a ViewModel which holds all those data(classes) as properties and return that to your view

public class CustomerViewModel
{
  public int ID { set;get;}
  public string Name { set;get;}
  public Address Address{ set;get;}
  public IEnumerable<Order> Orders { set;get;}

  public CustomerViewModel()
  {
    if(Address==null)
        Address=new Addres();
    if(Orders ==null)
        Orders =new List<Order>();

  }
}
public class Address
{  
   public string AddressLine1 { set;get;}
   //Other properties
}
public class Order
{  
   public int ORderID { set;get;}
   //Other properties
}

您GET Action方法

your GET Action method

public ActionResult Index(int id)
{
  var vm=new CustomerViewModel();

  vm.Name=repo.GetUser(id).Name;

  vm.Address=repo.GetAddressFromUserID(id);

  vm.Orders=repo.GetOrdersFromUser(id); 

  return View(vm);
}

和您的视图将被强类型TP CustomerViewModel

And your View will be strongly typed tp CustomerViewModel

@model CustomerViewModel

<p>@Model.Name</p>
<p>@Model.Address.AddressLine1</>
@foreach(var item in Model.Orders)
{
  <p>@item.OrderID</p>
}
