Add data from two tables in one view MVC 4

Question

I am trying to add data from two different table in one view. Here somne code: Code of viewmodel

public class ProductIndexData
{
    public IEnumerable<Order> Orders { get; set; }
    public IEnumerable<Magnet> Magnets { get; set; }
    public IEnumerable<Map> Maps { get; set; }
    public IEnumerable<Portrait> Portraits { get; set; }
    public IEnumerable<Tablet> Tablets { get; set; }
    public IEnumerable<Other> Others { get; set; }
}

Code of controller:

public ActionResult Index()
    {
        ProductIndexData products = new ProductIndexData();
        products.Magnets = (from o in db.Magnets select o).ToList();
        return View(products);
    }

Code of view:

@model List<SvLaserIS.ProductIndexData>
@{
    ViewBag.Title = "Product";
}

<h2>Product</h2>
<table>
@foreach (var item in Model) {
    foreach(SvLaserIS.Models.Magnet magnet in item) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => magnet.Count)
        </td>
        <td>
            @Html.DisplayFor(modelItem => magnet.Model)
        </td>
        <td>
            @Html.DisplayFor(modelItem => magnet.Color)
        </td>
        <td>
            @Html.DisplayFor(modelItem => magnet.FullPrice)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new {  }) |
            @Html.ActionLink("Details", "Details", new {  }) |
            @Html.ActionLink("Delete", "Delete", new {  }) 
        </td>
    </tr>
    }
}
    </table>

After compilation i ve got error in the second foreach cycle in view that says its not contait the definition for GetEnumerator. Looking for help with it :/

Answer 1

似乎您只是忘了指定要迭代item.Magnets属性：

foreach(SvLaserIS.Models.Magnet magnet in item.Magnets)

Answer 2

I solved it. Just passing single object in view and using single foreach cycle for each table in view. Thanks everyone for respones.

Answer 3

In model
--------

simple example 


 public class subdomain
   {

       public string Function { get; set; }
       public string SubDomain { get; set; }
       public string URL { get; set; }
       public Guid DomainId { get; set; }

   }
   public class emailserver
   {
       public string Priority { get; set; }
       public string MailExchanger { get; set; }
       public Guid DomainId { get; set; }
   }


  public class  tablevalues
   {
       public List<emailserver> emailserver { get; set; }

       public List<subdomain> subdomain { get; set; }
   }



in controller
-------------
tablevalues dto=new tablevalues();
dto.subdomain=from  p in context.tablename1  select p
dto.emailserver=from q in context.tablename2 select q
return View(dto);


in .cshtml
----------


 @model MVCDropDownlist.Models.tablevalues 

@{
    Layout = null;
}


 <table width="100%" border="0" cellspacing="0" cellpadding="0" id="tbsub" style="visibility: @(Model.subdomain.Count==0? "hidden" : "visible") " >
            <thead>
                <tr>

                </tr>
                <tr>
                    <th>Web Sub Domain</th>
                    <th>Function</th>
                    <th>Points To</th>
                </tr>
            </thead>
            <tbody>
                @if (Model != null && Model.subdomain.Count() > 0)

                        </td>
                        <td>@Html.DisplayFor(modelItem => item.Function)</td>
                        <td>@Html.DisplayFor(modelItem => item.URL)</td>
                    </tr>
