第一种方法：

注意引用：using System.Runtime.Serialization.Json;              using System.IO; static void Main(string[] args)        {            //IRace human = new Human();            //human.Showking();            //IRace orc =new Orc();            //orc.Showking();            var returnCitySN = "{ \"cip\": \"183.39.52.39\", \"cid\": \"440300\", \"cname\": \"广东省深圳市\"}";            Class1 class1 = ParseFormJson
     
      (returnCitySN);            Console.ReadKey();        }        public static T ParseFormJson
      
       (string szJson)        {            T obj = Activator.CreateInstance
       
        ();            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson)))            {                DataContractJsonSerializer dcj = new DataContractJsonSerializer(typeof(T));                return (T)dcj.ReadObject(ms);            }        }

//使用Json.NET类库需要引入的命名空间//-----------------------------------------------------------------------------using Newtonsoft.Json;//------------------------------------------------------------------------- EastGroup jsonEast = JsonConvert.DeserializeObject
     
      (strLine);//反序列化
