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 ParentType Parent { get; set; }
    public List<ChildType> Children { get; set; }
}

public ActionResult Edit()
{
    ParentViewModel viewModel = new ParentViewModel();
    viewModel.Parent = GetParentData();
    viewModel.Children = GetChildrenData();
    
    return View(viewModel);
}

@model ParentViewModel

@using (Html.BeginForm("Save", "ControllerName", FormMethod.Post))
{
    @Html.EditorFor(model => model.Parent)
    
    for (int i = 0; i < Model.Children.Count; i++)
    {
        @Html.EditorFor(model => model.Children[i])
    }
    
    <input type="submit" value="Save" />
}

[HttpPost]
public ActionResult Save(ParentViewModel viewModel)
{
    // 处理父类型和子类型的数据
    // 保存到数据库或进行其他操作
    
    return RedirectToAction("Index");
}
