C#后端接收前端json数组

方案一：

/// <summary>
    /// （APP端）查询购物车选中商品的总价
    /// </summary>
    public class CartTotalPriceRequestDto
    {
        /// <summary>
        /// UserID

        /// <summary>
        /// 购买数量
        /// </summary>
        public int Quantity { get; set; }
    }

============================================================

 /// <summary>
        /// （APP端）查询购物车选中商品的总价，测试
        /// </summary>
        /// <returns></returns>
        public ActionResult QueryCartTotalPrice(CartTotalPriceRequestDto req)
        {
            string resultJson = HttpAjaxHelper.ActionPost(req, "QueryCartTotalPrice", "Cart");
            var resultObj = JsonConvert.DeserializeObject<BaseResponse<decimal>>(resultJson);
            string data = JsonConvert.SerializeObject(resultObj.Result);
            return Json(JsonAjax.JsonResult("1", "查询成功", data, ""));
        }

============================================================

//（APP端）查询购物车选中商品的总价
                url: "/ShopUsers/QueryCartTotalPrice",
                data: {
                    "UserID": 4088,
                    "GoodsList": [
                      {
                          "SkuProductID": 6358,
                          "Quantity": 8,
                          "GoodsName": "贝德玛舒妍洁肤液",
                          "GoodsID": 1418
                      },
                      {
                          "SkuProductID": 6358,
                          "Quantity": 8,
                          "GoodsName": "贝德玛舒妍洁肤液",
                          "GoodsID": 1418
                      }
                    ]
                },

方案二：

============================================================

<script>
    $(function () {
        $("#btnOK").click(function () {

            var QueryCartTotalPriceObj =
                {
                    "UserID": "4083",
                    "GoodsList": {
                        "GoodsID": "12",
                        "GoodsName": "33",
                        "SkuProductID": "44",
                        "Quantity": "55"
                    }
                };
            var QueryCartTotalPriceJson = JSON.stringify(QueryCartTotalPriceObj);

            $.ajax({
                type: "Post", dataType: "application/json",
                //traditional: true,//布尔值，规定是否使用参数序列化的传统样式。这样后台数组变量才能接受到值

 

============================================================

//（APP端）查询购物车选中商品的总价
                url: "/ShopUsers/QueryCartTotalPrice",
                data: {
                    "RequestJson": QueryCartTotalPriceJson,                    
                },

============================================================

/// <summary>
        /// （APP端）查询购物车选中商品的总价，测试
        /// </summary>
        /// <returns></returns>
        public ActionResult QueryCartTotalPrice(CartTotalPriceRequestDto req)
        {
            string requestJson = Request["RequestJson"];
 }

多个参数也一样，"RequestJson"算是一个参数，需要多个参数自己加。

============================================================

方案三

前端ajax请求数据

var reregulationJson = JSON.stringify({
                "id": "3",
                "channelsource": "www",
                "tradedate": "2018-09-01",
                "status": "1",
                "opid": "1",
                "opname": "",
                "opdate": "2019-03-02"
            });
            var reregulationareadetailJson = JSON.stringify(
                [{
                    "id": "1",
                    "areacode": "类型编号",
                    "areaname": "南区",
                    "gj_amounttotal": "123456",
                    "gn_amounttotal": "777",
                    "gj_ticketcount": "999",
                    "gn_ticketcount": "111",
                    "gj_orders": "666",
                    "gn_orders": "999",
                    "clientcount": "333"
                }]
            );
            var reregulationairlinedetailJson = JSON.stringify(
                [
                    {
                        "id": "123",
                        "airlinecode": "航司编码789",
                        "airlinename": "航司名称",
                        "gj_ticketcount": "111",
                        "gn_ticketcount": "222"
                    },
                    {
                        "id": "123",
                        "airlinecode": "航司编码789",
                        "airlinename": "航司名称",
                        "gj_ticketcount": "999",
                        "gn_ticketcount": "333"
                    }
                ]);

            $.ajax({
                url: "/api/Regulate/AddRegulateMain",
                type: "post",
                dataType: "json",
                //data: {
                //    reRegulation: 123,
                //    reRegulationAreadetail: 456,
                //    reRegulationAirlinedetail: null
                //},


                data: {
                    reregulation: reregulationJson,
                    reregulationareadetail: reregulationareadetailJson,
                    reregulationairlinedetail: reregulationairlinedetailJson,
                },

注意：如果后端对象是List，前端的json必须中括号[]，不然反序列化会失败！

----------------------------------------------------------------------------------------------

后端接收数据

 

[HttpPost]
        public string AddRegulateMain()
        {
            string reRegulationJson = HttpContext.Current.Request["reRegulation"];
            string reRegulationAreadetailJson = HttpContext.Current.Request["reRegulationAreadetail"];
            string reRegulationAirlinedetailJson = HttpContext.Current.Request["reRegulationAirlinedetail"];

            Rs_regulation regulationObj = JsonConvert.DeserializeObject<Rs_regulation>(reRegulationJson);
            List<Rs_regulation_Areadetail> reRegulationAreadetailObj = JsonConvert.DeserializeObject<List<Rs_regulation_Areadetail>>(reRegulationAreadetailJson);
            List<Rs_regulation_Airlinedetail> reRegulationAirlinedetailObj = JsonConvert.DeserializeObject<List<Rs_regulation_Airlinedetail>>(reRegulationAirlinedetailJson);

            return "main";
        }

 

方案四：

public class RegulateController : ApiController

/// <summary>
        /// 调控列表启用选中项
        /// </summary>
        /// <param name="objRequest"></param>
        /// <returns></returns>
        public string Regulation_Enable(EnableRequest objRequest)
        {
            //var tst = request.idList;
            return ("成功");
        }

public class EnableRequest {
        public List<int> idList { get; set; }       
    }

 

/// 编辑调控维护
                url: "/api/Regulate/Regulation_Enable",
                type: "post",             
                dataType: "json",
                data: {
                    idList: [9,10,11]
                },
