Asp.Net MVC 读取json文件

有些系统上面的配置可以做成config里面的appsetting。这里要求写在json文件里面。

首先 添加命名空间

using Newtonsoft.Json;
using System.IO;
using Newtonsoft.Json.Linq;
using System.Web;

下面是我json文件里面的内容 因为西门下面的序号是 变动的就写在配置文件里面也好修改

{
  "StatisticalChart": {
    "": "/Common/CountReport/DefaultStatis",
    "": "/Common/CountReport/CustomerManagerStatis",
    "": "/Common/CountReport/FirstExamineStatis",
    "": "/Common/CountReport/QualityCheckStatis",
    "": "/Common/CountReport/ElectricFinalCheckStatis",
    "": "/Common/CountReport/ExecutiveDirectorStatis"
  },
  "NameGetCode":{
    "Default": "",
    "CustomerManager": "",
    "FirstExamine": "",
    "QualityCheck": "",
    "ElectricFinalCheck": "",
    "ExecutiveDirector": ""
  }
}

下面是读取StatisticalChart节点里面的内容 power权限参数 用户登录之后获得。

/// <summary>
        /// 通过角色读取配置文件返回地址
        /// </summary>
        /// <param name="power">权限编号</param>
        /// <returns></returns>
        public static string GetUrlByPower(string power)
        {
            string url = "";
            try
            {
                //文件路径
                string jsonfile = HttpContext.Current.Server.MapPath($"\\App_Data\\config\\StatisticalChartConfig.json");
                //打开文件
                System.IO.StreamReader file = System.IO.File.OpenText(jsonfile);
                //加载问卷
                JsonTextReader reader = new JsonTextReader(file);
                //转化为JObject
                JObject ojb = (JObject)JToken.ReadFrom(reader);
                //读取StatisticalChart节点
                var list = ojb["StatisticalChart"].ToString();
                JObject jo = (JObject)JsonConvert.DeserializeObject(list);
                var dat = jo[power];
                if (dat == null)
                    url = "";
                else
                    url = dat.ToString();
            }
            catch (Exception e)
            {
                url = "";
                throw new Exception($"初始化JSON流程配置失败:{e.Message}");
            }
            return url;
        }

另外一种 中国省市县的json文件

读取的方法（我是通过身份证号码获取信息用到的）

 //读取json文件获取代码对应的省市县
                string jsonfile =HttpContext.Current.Server.MapPath($"\\App_Data\\Config\\AreasData.json");
                StreamReader file = File.OpenText(jsonfile);
                JsonTextReader reader = new JsonTextReader(file);
                var obj = JToken.ReadFrom(reader).ToList();
                for (int i = ; i < obj.Count; i++)
                {
                    JObject jo = (JObject)JsonConvert.DeserializeObject(obj[i].ToString());
                    if (jo["zoneCode"].ToString() == AreasCodess)
                    {
                        var Data = new AreasCode()
                        {
                            Province = jo["province"].ToString(),
                            ProvinceCode = jo["provinceCode"].ToString(),
                            City = jo["city"].ToString(),
                            CityCode = jo["cityCode"].ToString(),
                            Country = jo["zone"].ToString(),
                            CountryCode = jo["zoneCode"].ToString()
                        };
                        list.Add(Data);
                        break;
                    }

                }

AreasCode是个实体类 接收参数的Model，AreasCodess是区域代码。读取json文件代码就这些 全面几步都是一样的 后面要看具体的json文件格式，就跟Ajax一样 返回来数据类型 是后台决定的你才好解析！

获取身份证信息也贴上吧，后面用到又来拿

/// <summary>
        /// 获取身份证信息
        /// </summary>
        /// <param name="identityCard">身份证号码</param>

        /// <returns>List->IDCard模型</returns>
        public static List<IDCard> GetIDCardInfo(string identityCard, bool ageIsTrue = true)
        {

            if (string.IsNullOrEmpty(identityCard))//为空返回null
                return null;
            else
            {
                if (identityCard.Length !=  && identityCard.Length != )//身份证号码只能为15位或18位其它不合法
                    return null;
            }
            List<IDCard> dCards = new List<IDCard>();
            IDCard card = new IDCard();
            string strSex = string.Empty;
            //530326 1994 1201 2521
            if (identityCard.Length == )//处理18位的身份证号码从号码中得到生日和性别代码
            {

                card.Birthday = identityCard.Substring(, ) + "-" + identityCard.Substring(, ) + "-" + identityCard.Substring(, );
                strSex = identityCard.Substring(, );//
            }
            //530323 670401 001的含义; 530为云南，03为曲靖 ，23是师宗，出生日期为1967年4月1日，顺序号为001。
            if (identityCard.Length == )

            else
                card.Sex = "男";
            string AreasCodess = identityCard.Substring(, );
            List<AreasCode> list = new List<AreasCode>();

                    if (jo["zoneCode"].ToString() == AreasCodess)
                    {
                        var Data = new AreasCode()
