本文探讨Mvc框架中后端如何处理前端发送的数据，重点在于反序列化的过程，包括接收JSON、XML等格式的数据并转化为对象的机制。

后端

 public ActionResult AddInfo(Array arra)
        {
            string z = ((string[])arra)[0];
            List<Root> rbList = JsonConvert.DeserializeObject<List<Root>>(z);//反序列化
            for (int i = 0; i < rbList.Count; i++)
            {
                string id = rbList[i].ScoreID;               
                var bk = db.ScoreInfo.Find(id);
                bk.UsualScore = rbList[i].UsualScore;
                bk.MiddleScore = rbList[i].MiddleScore;
                bk.FinalScore = rbList[i].FinalScore;
                bk.AbsentTime = rbList[i].AbsentTime;
                bk.GeneralScore = (Convert.ToDouble(bk.UsualScore) * 0.3 + Convert.ToDouble(bk.MiddleScore) * 0.3 + Convert.ToDouble(bk.FinalScore) * 0.4).ToString();
                db.SaveChanges();
            }
            var list = (from a in db.ScoreInfo
                        from b in db.UserInfo
                        from c in db.CourseInfo
                        from d in db.ClassInfo
                        where a.UserID == b.UserID && a.CourseID == c.CourseID && b.ClassesID == d.ClassesID
                        select new ScoreDM
                        {
                            ScoreID = a.ScoreID,
                            UserName = b.UserName,
                            IDNum = b.IDNum,
                            UsualScore = a.UsualScore,
                            MiddleScore = a.MiddleScore,
                            FinalScore = a.FinalScore,
                            AbsentTime = a.AbsentTime,
                            GeneralScore = a.GeneralScore,
                            ClassesName = d.ClassesName,
                            CourseName = c.CourseName
                        }).ToList();
            var p = list.OrderBy(x => x.ScoreID).Skip(0).Take(3).ToList();
            return Json(p);
        }

        //反序列化列表
        public class Root
        {
            public string ScoreID { get; set; }
            public string UsualScore { get; set; }
            public string MiddleScore { get; set; }
            public string FinalScore { get; set; }
            public string AbsentTime { get; set; }
        }

前端

 add: function () {
                var obj = document.getElementsByName("ids");
                var oba = document.getElementsByName("UsualScore"); var obb = document.getElementsByName("MiddleScore");
                var obc = document.getElementsByName("FinalScore"); var obd = document.getElementsByName("AbsentTime");
                for (var i = 0; i < obj.length; i++) {
                    var score = { ScoreID: obj[i].value, UsualScore: oba[i].value, MiddleScore: obb[i].value, FinalScore: obc[i].value, AbsentTime: obd[i].value };
                    ids.push(score);
                }
                $.post('@Url.Action("AddInfo")', { arra: JSON.stringify(ids) }, function (data) {
                    viewModel.people(data); IFRead();
                });
            }
