Question

我正在使用Northwind数据库，并且我在主题中收到此错误。所以这里是视图和控制器：

epublic class TestController : Controller
{
    private dbNorthwindEntities db = new dbNorthwindEntities();

    // GET: Test
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult GetOrders()
    {
        using (dbNorthwindEntities db = new dbNorthwindEntities())
        {
            //var orders = db.Orders.OrderBy(o => o.OrderID).ToList();

            var orders = db.Orders.Include(o => o.Customer).Include(o => o.Employee).Include(o => o.Shipper).OrderBy(o => o.OrderID).ToList();
            return Json(new { data = orders }, JsonRequestBehavior.AllowGet);
        }
    }

e@{
    Layout = null;
}

DataTables警告：table id = myDatatable - 无效的JSON响应。有关此错误的更多信息，请参阅http://datatables.net/tn/1
