ASP.NET MVC5如何在同一视图中编辑父类型和List<>类型的子类型

public class ParentViewModel
{
    public string ParentProperty { get; set; }
    public List<ChildViewModel> Children { get; set; }

    public ParentViewModel()
    {
        Children = new List<ChildViewModel>();
    }
}

public class ChildViewModel
{
    public int Id { get; set; }
    public string ChildProperty { get; set; }
}

@model ParentViewModel

@using (Html.BeginForm())
{
    @Html.EditorFor(m => m.ParentProperty)

    <table>
        <thead>
            <tr>
                <th>ID</th>
                <th>Child Property</th>
            </tr>
        </thead>
        <tbody>
            @Html.EditorFor(m => m.Children)
        </tbody>
    </table>

    <input type="submit" value="Submit" />
}

@model ChildViewModel

<tr>
    <td>@Html.HiddenFor(m => m.Id)</td>
    <td>@Html.EditorFor(m => m.ChildProperty)</td>
</tr>

public class YourController : Controller
{
    [HttpGet]
    public ActionResult Edit()
    {
        var viewModel = new ParentViewModel();
        // 初始化viewModel.Children
        return View(viewModel);
    }

    [HttpPost]
    public ActionResult Edit(ParentViewModel viewModel)
    {
        if (ModelState.IsValid)
        {
            // 处理数据保存逻辑
            return RedirectToAction("Success");
        }
        return View(viewModel);
    }
}
