1. 序列化 对象

 

/** 使用 Newtonsoft.Json 序列化对象 **/ [WebMethod] public String getPersonInfos() {     // 初始化数据     List < Pserson > mlist = new List < Pserson > ();     for (int i = 0; i < 5; i++)     {         Pserson mpersopn = new Pserson();         mpersopn.name = "张三";         mpersopn.sex = i % 2 == 0 ? "男" : "女";         mpersopn.age = 20 + i;         mlist.Add(mpersopn);     }     CallbackObject mcallback = new CallbackObject();     mcallback.falg = "200";     mcallback.message = "请求成功";     mcallback.result = mlist;     String str = JsonConvert.SerializeObject(mcallback);     return str; }

　　

 

2. 反序列化 json字符串

  /** 使用 Newtonsoft.Json 反序列化json字符串 **

[WebMethod] public List < Pserson > getPersonInfo() {     string jsonText = "[{'name':'张三','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; }

　　

 

 

var result = JsonConvert.DeserializeAnonymousType(client.Execute(request).Content, new { access_token = string.Empty, expires_in = string.Empty });var o2 = JsonConvert.DeserializeObject(json) as JObject;
