将数据收集对象从Jquery ajax方法传递到显示空对象的MVC控制器

Question

I'm try to pass data object to MVC controller using JQuery method. While I'm click submit button it will create data object in JavaScript method. Data Object is not null in Ajax method. When we passing it to MVC controller it hit the method correctly but data object is showing null.

I tried single object as well, but it also showing null.

This is JQuery Ajax Method:

$(function () {
    $('.save-user').on('click', function () {

        var tr = $(this).parents('tr:first');
        var SrcCountryId = $("#ExchangeRateSetUpHeader_SrcCountryId option:selected").val();
        var DestCountryId = $("#ExchangeRateSetUpHeader_DestCountryId option:selected").val();
        var SrcCurrencyId = $("#ExchangeRateSetUpHeader_SrcCurrencyId option:selected").val();
        var DestCurrencyId = $("#ExchangeRateSetUpHeader_DestCurrencyId option:selected").val();
        var Rate = $("#ExchangeRateSetUpHeader_Rate").val();
        var RemittanceSettlementId = tr.find("#RemittanceId").val();
        var CommPercentage = tr.find("#CommPercentage").val();
        var CommFixed = tr.find("#CommFixed").val();
        var SellRate = tr.find("#SellRate").val();
        var Id = tr.find("#ItemId").val();

        var ExchangeRateSetUp =
            {
                "Id": Id,
                "SrcCountryId": SrcCountryId,
                "DestCountryId": DestCountryId,
                "SrcCurrencyId": SrcCurrencyId,
                "DestCurrencyId": DestCurrencyId,
                "Rate": Rate,
                "RemittanceSettlementId": RemittanceSettlementId,
                "CommPercentage": CommPercentage,
                "CommFixed": CommFixed,
                "SellRate": SellRate
            };
        $.ajax({
            url: '/ExchangeRateSetUp/Create/',
            type: 'POST',
            data: JSON.stringify(ExchangeRateSetUp),
            contentType: 'application/json; charset=utf-8',
            success: function (data) {
                alert(data);
            }
        });
        });
        });

This is my MVC COntroller Method.

[HttpPost]
public JsonResult Create(ExchangeRateSetUp model)
{
   return Json("Success", JsonRequestBehavior.AllowGet);
}

Please help me to Sortout this issue. Thanks.

Answer 1

You are passing data as json string, hence you need to accept it as string in create method.

Change ExchangeRateSetUp object to String parameter in create method and then covert String to ExchangeRateSetUp object :

public JsonResult Create(String model)
{
   //convert String model into ExchangeRateSetUp here

   return Json("Success", JsonRequestBehavior.AllowGet);
}

Answer 2

same thing happened for me. the reason was the absence of { get; set; } in the c# class defined to accept model in controller.

Check whether your class ExchangeRateSetUp has { get; set; } for the properties
