在ASP.NET MVC视图中访问模型的属性 [英] Accessing the property of a model in ASP.NET MVC View

问题描述

我在访问通过视图的模型的属性之一时遇到问题.

I am having problems accessing one of the properties of the model I am passing a View.

模型的定义如下:

public class ProductBasket
{
    public ProductBasket()
    {
        Products = new List<ProductConfiguration>();
        Errors = new List<string>();
    }
    public List<ProductConfiguration> Products { get; set; }
    public List<string> Errors { get; set; }
}

在我看来，模型指令的声明如下:

In my view the model directive is declared like this:

@model MyApp.ViewModels.Product.ProductBasket

我无法在foreach循环中访问Products属性.在Visual Studio中，当我将Model变量悬停在循环中时，它显示:

I am unable to access the Products property in a foreach loop. In VisualStudio when I hover of the Model variable in the loop it shows:

List<MyApp.ViewModels.Product.ProductConfiguration> 
WebViewPage<List<MyApp.ViewModels.Product.ProductConfiguration>>.Model { get; }

这是我以前使用的上一个模型-我不知道为什么会出现这个模型?

This is the previous model I was using - I don't know why this is there?

我做了什么

本能告诉我，我应该可以使用Model.Products访问Products属性(请告诉我这是否不正确)，但是我不明白为什么视图没有通过ProductBasket?

Instinct tells me I should be able to access the Products property with Model.Products (please tell me if this is incorrect), but I don't understand why the view isn't being passed a ProductBasket?

推荐答案

看起来您正在将ProductConfiguration类对象的集合传递给视图.确保从操作方法向视图发送ProductBasket类的单个对象

Looks like you are passing a collection of ProductConfiguration class objects to the view. Make sure you are sending a single object of ProductBasket class to your view from your action method

public ActionResult Something()
{
  var vm = new ProductBasket();

 //The below line is hard coded for demo. You may replace with actual list from db.
  vm.Products.Add(new ProductConfiguration { Id=1,Name="test"});

  return View(vm);
}

假设您的ProductConfiguration类具有Id和Name属性.

Assuming your ProductConfiguration class has an Id and Name property.

您的视图应绑定到ProductBasket

@model YourNameSpaceHere.ProductBasket
<h1>Products</h1>

@foreach(var product in Model.Products)
{
  <h2>@product.Name</h2>
}
