C# 在返回视图中返回json值时未传递值

我有一个视图，我想以这种方式返回视图中的json值，但数据不返回。当删除return视图并只传递return json（）时，数据将显示在网格中。但格式不正确意味着像控制台窗口这样的数据显示无法在jqgrid中正确显示。我正在分享我正在使用的动作结果、json函数和网格

请回顾一下，并告诉我什么是解决方案？如何在返回视图中返回json值

Action

    public ActionResult Ownership_Detail(string MemberShipID)
                {
                    ViewBag.id = MemberShipID;
                    Ownership_D(MemberShipID);
                    return View(Json(ViewBag.objOwnershipDetail, JsonRequestBehavior.AllowGet));
