1. 序列化 物件

 /** 使用 Newtonsoft.Json 序列化物件 **/
        [WebMethod]
        public String getPersonInfos() {
            // 初始化資料
            List<Pserson> mlist = new List<Pserson>();
            for (int i = 0; i < 5;i++ )
            {
                Pserson mpersopn = new Pserson();
                mpersopn.name = "張三";
                mpersopn.sex = i % 2 == 0 ? "男" : "女";
                mpersopn.age = 20 + i;
                mlist.Add(mpersopn);
            }

            CallbackObject mcallback = new CallbackObject();
            mcallback.falg = "200";
            mcallback.message = "請求成功";
            mcallback.result = mlist;
            String str = JsonConvert.SerializeObject(mcallback);
            return str;
        }
 

2. 反序列化 json字串

 /** 使用 Newtonsoft.Json 反序列化json字串 **/
        [WebMethod]
        public List<Pserson> getPersonInfo()
        {  
          string jsonText = "[{'name':'張三','sex':'男','age':30},{'name':'李四','sex':'女','age':25}]";
          List<Pserson> personlist = JsonConvert.DeserializeObject<List<Pserson>>(jsonText);
          foreach(Pserson p in personlist){
              System.Diagnostics.Debug.WriteLine("\n\n");
               String str = "name = " + p.name + "\t sex = " + p.sex + "\t age = " +  p.age +"\n";
               System.Diagnostics.Debug.WriteLine(str);
          }
            return personlist;
        }
