MVC .NET Create Drop Down List from Model Collection in Strongly Typed view
提问by Colin Pear
So I have a view typed with a collection like so:
所以我有一个像这样的集合类型的视图：
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IList<DTO.OrganizationDTO>>" %>
The OrganizationDTO looks like this:
OrganizationDTO 看起来像这样：
public OrganizationDTO
{
int orgID { get; set; }
string orgName { get; set; }
}
I simply want to create a Drop Down List from the collection of OrganizationDTO's using an HTML helper but for the life of me I cant figure it out! Am I going about this the wrong way?
我只是想使用 HTML 帮助程序从 OrganizationDTO 的集合中创建一个下拉列表，但在我的一生中我无法弄清楚！我会以错误的方式解决这个问题吗？
Should I be using a foreach loop to create the select box?
我应该使用 foreach 循环来创建选择框吗？

I did a small example, with a model like yours:
我做了一个小例子，有一个像你这样的模型：
public class OrganizationDTO
{
public int orgID { get; set; }
public string orgName { get; set; }
}
and a Controller like:
和一个控制器，如：
public class Default1Controller : Controller
{
//
// GET: /Default1/
public ActionResult Index()
{
IList<OrganizationDTO> list = new List<OrganizationDTO>();
for (int i = 0; i < 10; i++)
{
list.Add(new OrganizationDTO { orgID = i, orgName = "Org " + i });
}
return View(list);
}
}
and in the view:
并在视图中：
<%= Html.DropDownListFor(m => m.First().orgID, new SelectList(Model.AsEnumerable(), "orgId","orgName")) %>

Try this:
尝试这个：
<%= Html.DropDownList("SomeName", new SelectList(Model, "orgID", "orgName"), "Please select Organization") %>
