在MVC中将视图中的数组值从视图发送到控制器而无需实体框架

Question

`hello friends

我在不使用实体框架的情况下开发主要详细数据输入表单。 为此，我有两张桌子进行交易和交易详细信息     我使用ajax调用将master和detail的值传递给控制器​​。     它运行良好，所有记录都在控制器中，我通过放置一个断点来检查它。     但问题是，在检查模型状态时，它不在里面。它使模型状态为假，并给出错误    “结果视图=展开结果视图将枚举IEnumerable。”

please help me to resolve my issue

我的Ajax通话视图     创建交易明细对象

        var dealDetail = {  "ItemSysSeq": "", "Qty": "", "UnitPrice": "" };

        // creating deal master objects

        var DealMaster = { "DealSysSeq": "", "DealCode": "", "DealName": "", "ActiveFromDate": "", "ActiveToDate": "", "TotalCost": "", "Discount": "", "Dealoffer": "", "Remarks": "", "DealDetails": [] };

        //  // Set Deals Master Value
        DealMaster.DealSysSeq = 0;
        DealMaster.DealCode = $("#DealCode").val();
        DealMaster.DealName = $("#DealName").val();
        DealMaster.ActiveFromDate = $("#dateFrom").val
        DealMaster.ActiveToDate = $("#dateTo").val();
        DealMaster.TotalCost = $("#lblTotal").val();
        DealMaster.Discount = $("#txtdiscount").val();
        DealMaster.Dealoffer = $("#txtoffer").val();
        DealMaster.Remarks = $("#txtremarks").val();


        //creating the array and set the deal detail values

        //$('#stockitemError').text('');
        var stockvalues = [];
        //var erroritemcount = 0;

        $('#Dealdetailitems  tr').each(function (tr) {

            //if (
            //    $('select.pc', this).val() == "0" ||
            //    $('.txtQty', this).val() == "" ||
            //    isNaN($('.txtQty', this).val()) ||
            //    $('.txtopeningBalance', this).val() == "" ||
            //    isNaN($('.txtopeningBalance', this).val())
            //)
            //{
            //    erroritemcount++;
            //    $(this).addClass('error');


            //}



            //else {


            dealDetail.ItemSysSeq = $('select.pc', this).val(),
            dealDetail.Qty = parseFloat($('.txtQty', this).val()),
            dealDetail.UnitPrice = parseFloat($('.txtUnitPrice', this).val())

            DealMaster.DealDetails.push(dealDetail);

            dealDetail = { "ItemSysSeq": "", "Qty": "", "UnitPrice": "" };

            //}

        });


        // Set Ajax Post

        $.ajax({

            url: '/DealMaking/Create',

            data: JSON.stringify(DealMaster),

            //traditional: true,

                if (result.Scccess == 1) {

                    //will send status from server side

                    alert('Successfully done.');
                }

                else {

         }
       }
   });
