訪問兩個模型（ASP.NET MVC3）的單個剃鬚刀視圖的問題

Question

View（Index.chtml）在訪問視圖中的兩個模型時返回0行。請參閱下面的代碼。我是ASP.NET新手，我仍在學習。我試圖調試，我看到表數據沒有正確傳遞。請幫助

================================================================================ 
Controller: (OrganizationCodesController.cs) 
================================================================================ 
namespace MvcProject.Controllers 
{ 
    public class OrganizationCodesController : Controller 
    { 
     // 
     // GET: /OrganizationCodes/ 

     public ActionResult Index() 
     { 
      List<TABLE_CODES> temp_codes = new List<TABLE_CODES>(); 
      List<TABLE_ORGANIZATIONS> temp_organizations = new List<TABLE_ORGANIZATIONS>(); 

      var viewModel = new OrganizationCodesModel(temp_codes, temp_organizations); 
      return View(viewModel); 

     } 
    }

Model: (OrganizationCodesModel.cs)

    public class OrganizationCodesModel 
    { 
     public List<TABLE_CODES> TABLE_CODES { get; set; } 
     public List<TABLE_ORGANIZATIONS> TABLE_CODES { get; set; } 

     public OrganizationCodesModel(List<TABLE_CODES> _codes, List<TABLE_ORGANIZATIONS> _organizations) 
     { 
      TABLE_CODES = _codes; 
      TABLE_ORGANIZATIONS = _organizations; 
     } 
    } 
}

@foreach (var item in Model.TABLE_CODES) { 
    <tr>

     @foreach (var item_1 in Model.TABLE_ORGANIZATIONS) 
     { 
      if (item.LOCATION == item_1.ID) 
      { 
      @item1.NAME

      } 
     }

     <td> 
     @item.RANK

     <td>

    </tr> 
}

Answer 1

Modiy您Model Class這樣的：

public class OrganizationCodesModel 
{ 
    public List<TABLE_CODES> listTABLE_CODES { get; set; } 
    public List<TABLE_ORGANIZATIONS> listTABLE_ORGANIZATIONS { get; set; } 
} 

我還添加文本 「清單」 作爲前綴列表的名稱將其與類名區分開來，否則列表名和類名相同。

現在好了，你也必須修改Index action method這樣的：

public ActionResult Index() 
    { 
     OrganizationCodesModel model = new OrganizationCodesModel(); 

     List<TABLE_CODES>listCodes = new List<TABLE_CODES> { 
      new TABLE_CODES {LOCATION = 1, RANK = 1, LEVEL =1}, 
      new TABLE_CODES{LOCATION = 2, RANK = 3, LEVEL = 12345} 
     }; 
     List<TABLE_ORGANIZATIONS> listOrganisation = new List<TABLE_ORGANIZATIONS> { 
      new TABLE_ORGANIZATIONS {ID = 1,NAME="ABC"}, 
      new TABLE_ORGANIZATIONS{ID = 2,NAME="XYZ"} 
     }; 

     model.ListTABLE_CODES = listCodes; 
     model.ListTABLE_ORGANIZATIONS = listOrganisation; 
     return View(model); 
    } 

，並在您View只需更換你的列表名稱是這樣的：

@foreach (var item in Model.listTABLE_CODES) 
@foreach (var item_1 in Model.listTABLE_ORGANIZATIONS) 

這是所有。現在，您將能夠看到你這樣的輸出：

Answer 2

List<TABLE_CODES> temp_codes = new List<TABLE_CODES>(); 
List<TABLE_ORGANIZATIONS> temp_organizations = new List<TABLE_ORGANIZATIONS>(); 

var viewModel = new OrganizationCodesModel(temp_codes, temp_organizations); 

您instanciating兩個空單...

，你應該把你的名單東西！

像

List<TABLE_CODES> temp_codes = GetTempCodesFromSomewhere(); 

或

List<TABLE_CODES> temp_codes = new List<TABLE_CODES> { 
    new TABLE_CODES {LOCATION = 1, RANK = 1, LEVEL =1}, 
    new TABLE_CODES{LOCATION = 2, RANK = 3, LEVEL = 12345} 
};
