c# 使用 Newtonsoft.Json 序列化json字符串以及,反序列化对象

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;
