Json 集合传入 mvc action 中

action 中

model对象 的list集合作为参数，如图

那jq拼接json的格式我是这样写的

     function ss() {
            var DishesComposition = '{"DishesComModel":[';
      
  
            $('.cailiaohide').each(function () {
   
                DishesComposition += '{ "id": "0", "pid": "' + modelid + '", "product": "' + modelname + '", "rid": "' + cailiaoid + '", "num": "' + nums + '", "ownership": "' + ownership + '" },';});
            拼接json字符串尾部
            DishesComposition +=']}';
          
           json字符串转为json集合
            var dvalues = JSON.parse(DishesComposition);

            if (isvalide) {
                $.ajax({
                    type: "POST",
                    cache: false,
                    dataType: "json",
                    url: "Combination",
                    data: dvalues,
                    success: function (result) {
                        if (result.state == 'OK') {
                            alert(result.msg);
                            location.href = '/DishesComposition?ownership=' + ownership;
                        }
                        else {
                            alert(result.msg);
                        }
                    },
                    error: function (result) {
                        alert(result);
                    }

                });
            }
        }
    

这样action就能获取到 集合List<DishesComModel> DishesComModel 的参数，action方法的参数名要和json参数的key值，也就是

DishesComModel 一样。
