数据表在表单提交时未将 rowid 返回给 asp.net MVC 控制器

我无法在表单提交时将 rowid 从 jquery 数据表获取到我的控制器。

请在下面找到 html 代码：

 <form id="frm-example" action="@Url.Action("Index", "Home")" method="POST">
    <table id="example" class="display select" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th><input name="select_all" value="1" type="checkbox"></th>
                <th>User ID</th>
                <th>User Name</th>
            </tr>
        </thead>
    </table>
    <hr>
    <p>
        <input type="button" value="Add" class="btn btn-success" onclick="location.href='@Url.Action("Create", "UserProfile")'" />
        <button type="submit" id="frm-example" class="btn btn-danger" value="Delete">Delete</button>
    </p>
<pre id="example-console">
</pre>
</form>

请在控制器中找到我的代码。

  namespace DOSApplication.Controllers
  {
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Index(string[] id)
        {

            return View("Index");
        }
        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";
            return View();
        }
        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";
            return View();
        }
    }
}

主控制器的索引操作中的值显示为空。
