    public class Product
    {
        [DisplayName("產品名稱")]
        public string Name { get; set; }
    }
 
    public class Category
    {
        [DisplayName("類別名稱")]
        public string Name { get; set; }
        private IList<Product> _products = new List<Product>();
 
        public IList<Product> Products
        {
            get { return _products; }
            set { _products = value; }
        }
    }

思路

控制器方法能接收的格式為：
Category.Name
Category.Products[0].Name
Category.Products[1].Name
...

前臺視圖使用jquery動態(tài)生成input，并把input的name屬性設置成Category.Products[i].Name格式。

Home/Index.cshtml視圖

@model AddingMultipleNestedData.Models.Category
 
@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
 
@using (Html.BeginForm("Create", "Home", FormMethod.Post, new {id = "addForm"}))
{
    <div>
        @Html.LabelFor(m => m.Name)
        @*@Html.EditorFor(m => m.Name)*@
        @Html.TextBox("Category.Name")
    </div>
    <div id="products"></div>
    <div>
        <input id="btnAddProduct" type="button" value="添加產品"/>
    </div>
    <div>
        <input type="submit" value="提交"/>
    </div>
}
 
@section scripts
{
    <script type="text/javascript">
        $(function() {
            var noOfProducts = 0;
            $('#btnAddProduct').click(function() {
                var product = getNestedName("Category.Products", noOfProducts);
                noOfProducts++;
                $('#products').append("<input type='text' name='"+product+".Name' /><p>");
            });
 
        });
 
        function getNestedName(itemName, itemNumber) {
            return (itemName + "[" + itemNumber + "]");
        }
    </script>
}

沒有添加產品前：

添加產品集合：

HomeController

        public ActionResult Index()
        {
            return View();
        }
 
        [HttpPost]
        public ActionResult Create(Category category)
        {
            return View();
        }
