    </table>
    <input type="submit" value="提交" />
}
        [HttpPost]
        public ActionResult Index(List<mvctest.Models.SysUser> list)
        {
            return View(db.SysUsers.ToList());
        }

注意Action参数名称与view中的list名称一致才可以,这里view中Name属性使用了list[0].username这样的名称,即view中list的名称为list,所以Action参数也要命名为list
