json字符窜转对象

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<Class1>(returnCitySN);
            Console.ReadKey();
        }
        public static T ParseFormJson<T>(string szJson)
        {
            T obj = Activator.CreateInstance<T>();
            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson)))
            {
                DataContractJsonSerializer dcj = new DataContractJsonSerializer(typeof(T));
                return (T)dcj.ReadObject(ms);
            }
        }

第二种方法:

//使用Json.NET类库需要引入的命名空间
//-----------------------------------------------------------------------------
using Newtonsoft.Json;
//-------------------------------------------------------------------------

 EastGroup jsonEast = JsonConvert.DeserializeObject<EastGroup>(strLine);//反序列化
