用ajax post array数组到Mvc web Api后台接受不到的问题

普通string数组

            $.ajax({                    type: "post",                    url: "http://localhost:8902/api/PriceRatio/Add",                    data: {"":["123","123","12"]},                    dataType: "json",                    traditional: true,                    success: function (msg) {                    }                });

        [HttpPost]        public bool Add([FromBody]string[] ids)        {            return true;        }

对象数组：

 for (var i = 0; i < 3; i++) {                    prices.push({                        Id:"123",                        UpdateTime: null,                        Type: "other",                        Price: 123,                        Url: "www",                        Remark: "demo",                    });                };                $.ajax({                    type: "post",                    url: "http://localhost:8902/api/PriceRatio/Add",                    data: { "": prices},                    dataType: "json",                    traditional: false,                    success: function (msg) {                    }                });

        [HttpPost]        public bool AddPriceRatios([FromBody]List<PriceRationModel> priceRations)        {            if (ModelState.IsValid)            {                return PriceRatioBLL.AddPriceRatios(priceRations) > 0;            }            else            {                throw new Exception(BadRequest(ModelState).ModelState.Values.FirstOrDefault()?.Errors.FirstOrDefault()?.ErrorMessage);            }        }

如果Post是string数组或者int数组，则ajax中traditional: true,

如果Post是对象数组，则ajax中traditional: false,否则对象将为空
