ASP.NET MVC DropDown编辑器模板

我正在寻找使用MVC创建下拉列表编辑器模板的最佳方法.似乎有各种各样的方法,但我找不到任何最好的方法,每个人似乎都有不同的方法.我也在使用带有Razor的MVC3,所以首选一种适用于此的方法.

有很多方法和说法哪个最好是主观的,可能不适用于你的场景,这是你忘记在你的问题中描述的方式.我是这样做的:

模型:

public class MyViewModel
{
    public string SelectedItem { get; set; }
    public IEnumerable Items { get; set; }
}

public class Item
{
    public string Value { get; set; }
    public string Text { get; set; }
}

控制器:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new MyViewModel
        {
            // TODO: Fetch this from a repository
            Items = new[] 
            {
                new Item { Value = "1", Text = "item 1" },
                new Item { Value = "2", Text = "item 2" },
                new Item { Value = "3", Text = "item 3" },
            }
        };
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        if (!ModelState.IsValid)
        {
            // redisplay the view to fix validation errors
            return View(model);
        }

        // TODO: The model is valid here => 
        // perform some action using the model.SelectedItem 
        // and redirect to a success page informing the user
        // that everything went fine
        return RedirectToAction("Success");
    }
}

查看(~/Views/Home/Index.cshtml):

@model MyApp.Models.MyViewModel

@{ Html.BeginForm(); }
    @Html.EditorForModel()
    
@{ Html.EndForm(); }

编辑模板(~/Views/Home/EditorTemplates/MyViewModel.cshtml):

@model MyApp.Models.MyViewModel

@Html.DropDownListFor(x => x.SelectedItem, 
    new SelectList(Model.Items, "Value", "Text"))
