1层JSON

    List<RefillData_Model> list = new List<RefillData_Model>();//List存数据
DataTable refilldt = fill.GetFacInfo();
                        for (int j = 0; j < refilldt.Rows.Count; j++)
                        {
                            RefillDataFac_Model refill = new RefillDataFac_Model();
                            refill.action = refilldt.Rows[j]["action"].ToString();
                            refill.facility = refilldt.Rows[j]["facility"].ToString();
                            refill.hSerial = refilldt.Rows[j]["Head_serial"].ToString();
                            refill.so = refilldt.Rows[j]["so"].ToString();
                            refill.refno = refilldt.Rows[j]["refno"].ToString();
                            refill.partNum = refilldt.Rows[j]["partno"].ToString();
                            refill.slot = refilldt.Rows[j]["slot"].ToString();
                            refill.qty = refilldt.Rows[j]["planqty"].ToString();
                            refill.Sdte = refilldt.Rows[j]["sdte"].ToString();
                            refill.stme = refilldt.Rows[j]["stme"].ToString();
                            refill.reelcut = refilldt.Rows[j]["reelcut"].ToString();
                            refill.mdte = refilldt.Rows[j]["mdte"].ToString();
                            refill.mtme = refilldt.Rows[j]["mtme"].ToString();
                            refill.soseq = refilldt.Rows[j]["soseq"].ToString();
                            refill.slotserial = refilldt.Rows[j]["SlotSerial"].ToString();
                            refilldata.Add(refill);
                        }
                        string json = JsonConvert.SerializeObject(refilldata);

以上是3层和1层的JSON数组写法 通过NewtonSoftJson 当然也可以用JSONhelper里面的拼接方法 在需要使用灵活的JSON时可以自己拼接。

反序列化

            List<AbNormallReport_Model> datalist = new List<AbNormallReport_Model>();
            datalist = Newtonsoft.Json.JsonConvert.DeserializeObject<List<AbNormallReport_Model>>(data);
