mvc返回json数据

不知道是不是你要的那种，这是用于返回简单数据表达数据操作成功，中间复杂代码掠过看首尾

 [HttpPost]
        public IActionResult DataRole(int id, string[] complay_arry, string[] site_arry, string[] equipment_arry)
        {
            var message = "修改失败！";
            int success = ;
            try
            {
                using (var transaction = _session.BeginTransaction())
                {

                    for (int i = ; i < complay_arry.Length; i++)
                    {
                        for (int j = ; j < site_arry.Length; j++)
                        {
                            for (int k = ; k < equipment_arry.Length; k++)
                            {

                }

            catch (Exception)
            {

                message = "修改失败！";
            }

            return Json(new { success, message });
        }

在视图接收

 $.ajax({
            type: "post",//提交方式
            data: { complay_arry: complay_arry, site_arry: site_arry, equipment_arry: equipment_arry, id: id },//查询的参数
            url: "/Role/DataRole",//提交的路径
            success: function (res2) {
                alert(res2.message);
                location.href = "/Role/Edit/"+id;
            }
        })

成功之后跳转界面
