IList没有正确回发到控制器

标签： c# asp.net-mvc-4

我遇到了需要批量编辑并将记录发回我的mvc 4控制器的情况。我有一个自定义视图模型的列表，我可以在索引视图上正确传递和编辑。但是，当我提交表单并尝试访问post方法中的列表时，我无法检索相同的列表。最多，我只能得到第一条记录，或者我得到空。如何获取整个对象列表？

视图模型：

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;

namespace SitefinityWebApp.Mvc.Models
{
    public class CheckoutViewModel
    {
        public string Title { get; set; }
    [Required]
        public string FirstName { get; set; }
        [Required]
        public string LastName { get; set; }
        [Required]
        public string Email { get; set; }
        [Required]
        public string Phone { get; set; }
        public string PTIN { get; set; }
        public string Sku { get; set; }
        public Guid CartOrderId { get; set; }
        public string IRSCourseNumber { get; set; }
        public string Id { get; set; }

    }
}

控制器：

public ActionResult Index()
    {
        Guid gdShoppingCartId = cmmObj.GetShoppingCartId();
        List<SitefinityWebApp.Custom.Surgent.sf_ec_cart_detail> cartdetails = new List<SitefinityWebApp.Custom.Surgent.sf_ec_cart_detail>();
        SubSiteProductRepository ssp = new SubSiteProductRepository();
        List<CheckoutViewModel> cvml = new List<CheckoutViewModel>();

        if (gdShoppingCartId != Guid.Empty && gdShoppingCartId != null)
        {
            cartdetails = DbContext.sf_ec_cart_details.Where(d => d.cart_order_id == gdShoppingCartId).ToList();
            if (cartdetails.Count > 0)
            {
                if (cartdetails.Where(c => c.need_registration2 == "true").Count() > 0)
                {
                    var webinars = LoadWebinar();
                    //WebinarViewModel wvm = new WebinarViewModel();
                    foreach (DataRow row in webinars.Rows)
                    {
                        cvml.Add(new CheckoutViewModel
                        {
                            Sku = row["sku"].ToString(),
                            Id = row["id"].ToString(),
                            Title = row["title_"].ToString(),
                            CartOrderId = gdShoppingCartId,
                            IRSCourseNumber = row["irsCourseNumber"].ToString()
                        });
                        //foreach (DataColumn column in table.Columns)
                        //{
                        //    object item = row[column];
                        //    // read column and item
                        //}
                    }
                }


            }
        }
        return View(cvml);
    }

    [HttpPost]
    public ActionResult Index([Bind(Prefix="cvm.")]IList<CheckoutViewModel> cvm)
    {
        int viewmodelerror = 0;
        foreach(CheckoutViewModel c in cvm){
            if (ModelState.IsValid)
            {
                //if (c.PTIN != null || c.PTIN != "")
                    //return Redirect("~/CheckOut");
            }
            else
            {
                viewmodelerror++;
                //return View(cvm);
            }
        }

        return View(cvm);
            //return new EmptyResult();
    }

编辑：我想出了如何修复它。我在Html.BeginForm（）方法中有表单标签（我不想要）。事后看来，有意义的是，正在创建多个表单，但只能提交第一个表单。代码的工作版本如下。谢谢你的帮助，斯蒂芬：）
