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：）
