推荐答案

你可以有一个视图模型:

You could have a view model:

public class MyViewModel
{
    public int Id { get; set; }
    public bool IsChecked { get; set; }
}

控制器:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var model = new[] 
        {
            new MyViewModel { Id = 1, IsChecked = false },
            new MyViewModel { Id = 2, IsChecked = true },
            new MyViewModel { Id = 3, IsChecked = false },
        };
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(IEnumerable<MyViewModel> model)
    {
        // TODO: Handle the user selection here
        ...
    }
}

一个视图(~/Views/Home/Index.cshtml):

@model IEnumerable<AppName.Models.MyViewModel>
@{
    ViewBag.Title = "Home Page";
}
@using (Html.BeginForm())
{
    @Html.EditorForModel()
    <input type="submit" value="OK" />
}

和相应的编辑器模板(~/Views/Home/EditorTemplates/MyViewModel.cshtml):

and the corresponding Editor template (~/Views/Home/EditorTemplates/MyViewModel.cshtml):

@model AppName.Models.MyViewModel
@Html.HiddenFor(x => x.Id)           
@Html.CheckBoxFor(x => x.IsChecked)

现在，当您提交表单时，您将获得一个值列表以及每个值是否被选中.

Now when you submit the form you would get a list of values and for each value whether it is checked or not.
