  @model IEnumerable的＆LT; SportsStore.Entities.Towar＆GT;
@model IEnumerable的＆LT; SportsStore.Entities.Kategorie＆GT;
@ {
    ViewBag.Title =清单;
}＆LT; H2＆GT;列表与LT; / H＆GT;@foreach（以型号VAR P）

    ＆LT; D​​IV CLASS =项＆GT;
         ＆LT; H3＆GT; @ p.Nazwa＆LT; / H3 GT＆;
         @ p.Opis
         ＆LT; H4＆GT; @ p.Cena.ToString（C）＆LT; / H4＆GT;
    ＆LT; / DIV＆GT;
}
 

解决方案

您只能有每个视图一个模型。但是你可以用另一目的是declarate模型：

 公共类SomeViewModel
{
   公共IEnumerable的＆LT; Towar＆GT; Towars;
   公共IEnumerable的＆LT;类别及GT;分类;   公共SomeViewModel（IEnumerable的＆LT; Towar＆GT; towars，IEnumerable的＆LT;分类和GT;类）{
     Towars = towars;
     类别=类别;
   }
}
 

，然后用它在你看来是这样的：

  @model SportsStore.Entities.SomeViewModel@foreach（在Model.Towars VAR项）
{
  ＆LT; D​​IV CLASS =项＆GT;
    ＆LT; H3＆GT; @ p.Nazwa＆LT; / H3 GT＆;
    @ p.Opis
    ＆LT; H4＆GT; @ p.Cena.ToString（C）＆LT; / H4＆GT;
  ＆LT; / DIV＆GT;
}
@foreach（在Model.Categories VAR项）{
  @ item.Name @ *或你需要什么到这里@ *
}
 

我也建议你在MVC中使用英文名字。它更清晰的阅读和理解。）

I would like to using two times @model to get data from another part of my website is it possible? Because now I have got error but if I have only this first @model everything working correct.

Look -> MVC 3 - Exception Details: System.InvalidOperationException

Error 2 'SportsStore.Entities.Kategorie' does not contain a definition for 'Opis' and no extension method 'Opis' accepting a first argument of type 'SportsStore.Entities.Kategorie' could be found (are you missing a using directive or an assembly reference?) c:\Users\Rafal\Desktop\MVC ksiązka\moj projekt\sklep\SportsStore.WebUI\Views\Product\List.cshtml 16 4 SportsStore.WebUI

@model IEnumerable<SportsStore.Entities.Towar>
@model IEnumerable<SportsStore.Entities.Kategorie>


@{
    ViewBag.Title = "List";
}

<h2>List</h2>

@foreach (var p in Model)
{
    <div class="item">
         <h3>@p.Nazwa</h3>
         @p.Opis
         <h4>@p.Cena.ToString("c")</h4>
    </div>
}

解决方案

You only can have one Model per View. But you can use another object to declarate the model:

public class SomeViewModel
{
   public IEnumerable<Towar> Towars;
   public IEnumerable<Category> Categories;

   public SomeViewModel(IEnumerable<Towar> towars, IEnumerable<Category> categories) {
     Towars = towars;
     Categories = categories;
   }
}

And then use it in your view like this:

@model SportsStore.Entities.SomeViewModel

@foreach (var item in Model.Towars)
{
  <div class="item">
    <h3>@p.Nazwa</h3>
    @p.Opis
    <h4>@p.Cena.ToString("c")</h4>
  </div>
}
@foreach (var item in Model.Categories) {
  @item.Name @* or what you need down here *@
}

I would also recommend you to use english names in MVC. It's more clear to read and understand ;).
