JSON解析

用Newtonsoft.Json.dll 下载 http://json.codeplex.com/

1：简单的单层JSON解析

如： //"{ \"result\": 1, \"adminId\": 2, \"customerId\": 1}"

 JObject jobj = JObject.Parse(resultStr);                    int result = (int)jobj["result"];                    int adminId = (int)jobj["adminId"];                    int customerId = (int)jobj["customerId"];

2：简单的双层解析

如：

 JObject jo = JObject.Parse(result);            int resulta = (int)jo["result"];JArray jas = (JArray)jo["customers"];                string createTime = jas[0]["createTime"].ToString();                int customerId = (int)jas[0]["customerId"];                int parkingCount = (int)jas[0]["parkingCount"];                int type = (int)jas[0]["type"];                string companyName = jas[0]["companyName"].ToString();                string modifyTime = jas[0]["modifyTime"].ToString();

如果存在内容有

类似这种的,就只要知道rechargeRecord下面有多少个数组就好了。Jraay有一个Count的方法，可以得到个数

JArray jas = (JArray)jo["rechargeRecord"];                int joa = jas.Count();                for (int i = 0; i < joa; i++)                {                    string createTime = (string)jas[i]["createTime"];                    DateTime createDate = GetNoralTime(createTime);                    int insideCarId = (int)jas[i]["insideCarId"];                    int customerId = (int)jas[i]["customerId"];                    int vChargeRecrodId = (int)jas[i]["vChargeRecrodId"];                    int type = (int)jas[i]["type"];                    int rechargeRecordId = (int)jas[i]["rechargeRecordId"];                                       string sql = "";                    if (type == 0)                        sql = "insert into tb_rechargeRecrod values (" + rechargeRecordId + "," + customerId + "," + insideCarId + "," + vChargeRecrodId + ",'" + createDate + "')";                    else                        sql = "update tb_rechargeRecrod set createTime='" + createTime + "' where rechargeRecordId=" + rechargeRecordId;                    DataBase.UpdateDB(sql);                }

这样就可以得到每个数组的数据。。。嘎嘎

嗯。自己瞎搞出来的。感觉怪怪的。
