表单数据批量提交，后台批量接收并保存

前台JS代码

 $("#btn_save").click(function (data) {
            var values = $("#from_jbxx").serializeArray();
            var strdata = {};
            $.each($("#from_jbxx").serializeArray(), function (a, b) { strdata[b.name] = b.value; });
            if ($("#from_jbxx").validationEngine('validate')) {

                $.ajax({
                    type: 'POST',
                    url: getFnDataUrl("HttpAshx/StudentInfo.ashx", "SaveStudentTurnover"),
                    data: JSON.stringify(strdata),
                    success: function (strResult) {
                        var res = $.parseJSON(strResult) || {};
                        if (res.Succeed) {
                            alert(res.Message);
                            location.href = "/Student/UserCenter.aspx";
                        } else {
                            alert(res.Message);
                        }
                    }
                });
                return false;
            } else {
                return false;
            }
        });

后台代码

        public void SaveStudentTurnover(HttpContext context)
        {

            byte[] bytes = new byte[context.Request.InputStream.Length];
            context.Request.InputStream.Read(bytes, 0, bytes.Length);
            var values = System.Text.Encoding.UTF8.GetString(bytes).JsonDeserialize<Dictionary<string, string>>();

            string strId = values["Id"] ?? "";
            var model = _gdc.GetDataSet<XjStudentTurnover>().FirstOrDefault(p => p.Id == strId);
            if (model == null)
            {
                model = XjStudentTurnover.CreateXjStudentTurnover(_gdc.GetNewCode<XjStudentTurnover>());
                model.InnerDeleteFlag = false;
                model.StudentId = values["StudentId"] ?? "";
                _gdc.AddObject(model);
            }

            model.LoadFrom(values);
            _gdc.SaveChanges();
            DtHttpContext.ReturnMesg(AjaxResult.Success("保存成功~！"), context);
            return;
        }
