using nested class within class doesnt works in mvc 3

Question

Hi I have included nested class within a class to use it in a view but it doesnt show up the properties of that nested class below is the class, I want to use sku in the view : View:

@model Nop.Web.Models.Catalog.CategoryModel
<div class="product-item">
<h2 class="product-title">
@Model.Name
 </h2>

<div class="description">
      **@Model.ProductVariantModels.Select(x => x.Sku)//doesnt works** // partial class productvariant

</div>
<div class="add-info">
@Model.Name <br/> @Model.FullDescription //values from class CategoryModel 
  </div>
</div>

Model:

public class CategoryModel : BaseEntityModel
{
    public CategoryModel()
    {
        ProductVariantModels = new List<ProductVariantModel>();
    }
public string Name { get; set; }
public string FullDescription { get; set; }
public string MetaKeywords { get; set; }
public string MetaDescription { get; set; }
public string MetaTitle { get; set; }
public IList<ProductVariantModel> ProductVariantModels { get; set; }

public class ProductVariantModel : BaseNopEntityModel
    {
    public string Name { get; set; }
    public bool ShowSku { get; set; }
    public string Sku { get; set; }
    public string Description { get; set; }
    }

}

That's a nested class, not a partial class. – SLaks Nov 17 '11 at 14:16 — SLaks, Nov 17 '11 at 14:16
Why doesn't it work? What happens? – SLaks Nov 17 '11 at 14:18 — SLaks, Nov 17 '11 at 14:18

ProductVariantModels is a List. You have to enumerate the List.

@foreach (var pvModel in Model.ProductVariantModels) {
   @pvModel.Sku
}

@if(Model.ProductVariantModels.Count > 0) { foreach (var sku in Model.ProductVariantModels) {@sku.Sku } } – Mr A Nov 17 '11 at 14:18
According to the `CategoryModel ` class, it doesn't have a `Sku` property. only `ProductVariantModel` has a `Sku`. – Daniel A. White Nov 17 '11 at 14:20
yeh i want to use that property – Mr A Nov 17 '11 at 14:22

If you're using HtmlHelpers, you have to use a for loop with an index rather than a foreach loop.

As explained really well here, the automatic model binding expects field input names to have a 'dot' notation like Property.SubProperty.SubSub... to match the instance properties when assigning -- but if you render them in a foreach loop they won't have the full expression, and thus won't output the full 'dot' notation.
