有些系統上面的配置能夠作成config裏面的appsetting。這裏要求寫在json文件裏面。json

首先添加命名空間

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

下面是我json文件裏面的內容由於西門下面的序號是變更的就寫在配置文件裏面也好修改

{
  "StatisticalChart": {
    "0": "/Common/CountReport/DefaultStatis", 
    "68": "/Common/CountReport/CustomerManagerStatis", 
    "98": "/Common/CountReport/FirstExamineStatis",
    "84": "/Common/CountReport/QualityCheckStatis", 
    "112": "/Common/CountReport/ElectricFinalCheckStatis", 
    "70": "/Common/CountReport/ExecutiveDirectorStatis" 
  },
  "NameGetCode":{
    "Default": "0",
    "CustomerManager": "68",
    "FirstExamine": "98",
    "QualityCheck": "84",
    "ElectricFinalCheck": "112",
    "ExecutiveDirector": "70"
  }
}

下面是讀取StatisticalChart節點裏面的內容 power權限參數用戶登陸以後得到。

/// <summary>
        /// 經過角色讀取配置文件返回地址
        /// </summary>
        /// <param name="power">權限編號</param>
        /// <returns></returns>
        public static string GetUrlByPower(string power)
        {
            string url = "";
            try
            {
                //文件路徑
                string jsonfile = HttpContext.Current.Server.MapPath($"\\App_Data\\config\\StatisticalChartConfig.json");
                //打開文件
                System.IO.StreamReader file = System.IO.File.OpenText(jsonfile);
                //加載問卷
                JsonTextReader reader = new JsonTextReader(file);
                //轉化爲JObject
                JObject ojb = (JObject)JToken.ReadFrom(reader);
                //讀取StatisticalChart節點
                var list = ojb["StatisticalChart"].ToString();
                JObject jo = (JObject)JsonConvert.DeserializeObject(list);
                var dat = jo[power];
                if (dat == null)
                    url = "";
                else
                    url = dat.ToString();
            }
            catch (Exception e)
            {
                url = "";
                throw new Exception($"初始化JSON流程配置失敗:{e.Message}");
            }
            return url;
        }

另一種中國省市縣的json文件

讀取的方法（我是經過身份證號碼獲取信息用到的）

 //讀取json文件獲取代碼對應的省市縣
                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 = 0; 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是個實體類接收參數的Model，AreasCodess是區域代碼。讀取json文件代碼就這些全面幾步都是同樣的後面要看具體的json文件格式，就跟Ajax同樣返回來數據類型是後臺決定的你纔好解析！

獲取身份證信息也貼上吧，後面用到又來拿

/// <summary>
        /// 獲取身份證信息
        /// </summary>
        /// <param name="identityCard">身份證號碼</param>
        /// <param name="ageIsTrue">顯示年齡是不是真實大小（當前年份減去出生年份 月份 日期都要計算）</param>
        /// <returns>List->IDCard模型</returns>
        public static List<IDCard> GetIDCardInfo(string identityCard, bool ageIsTrue = true)
        {

            if (string.IsNullOrEmpty(identityCard))//爲空返回null
                return null;
            else
            {
                if (identityCard.Length != 15 && identityCard.Length != 18)//身份證號碼只能爲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 == 18)//處理18位的身份證號碼從號碼中獲得生日和性別代碼
            {
                //出身年月日
                card.Birthday = identityCard.Substring(6, 4) + "-" + identityCard.Substring(10, 2) + "-" + identityCard.Substring(12, 2);
                strSex = identityCard.Substring(14, 3);//
            }
            //530323 670401 001的含義; 530爲雲南，03爲曲靖 ，23是師宗，出生日期爲1967年4月1日，順序號爲001。
            if (identityCard.Length == 15)
            {
                card.Birthday = "19" + identityCard.Substring(6, 2) + "-" + identityCard.Substring(8, 2) + "-" + identityCard.Substring(10, 2);
                //性別代碼
                strSex = identityCard.Substring(12, 3);
            }

            card.Age = CalculateAge(card.Birthday, ageIsTrue);//根據生日計算年齡
            if (int.Parse(strSex) % 2 == 0)//性別代碼爲偶數是女性奇數爲男性
                card.Sex = "女";
            else
                card.Sex = "男";
            string AreasCodess = identityCard.Substring(0, 6);
            List<AreasCode> list = new List<AreasCode>();

                {
                    JObject jo = (JObject)JsonConvert.DeserializeObject(obj[i].ToString());
                    if (jo["zoneCode"].ToString() == AreasCodess)
                    {
