Newtonsoft.Json使用

一、NuGet包提交Newtonsoft.Json

二、引用命名空间
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

三、命名空间
1、Newtonsoft.Json
JsonConvert，json字符串转换为object对象
object obj = JsonConvert.DeserializeObject(objstring);

JsonConverter
JsonSerializer
JsonReader
JsonReader reader = new JsonTextReader(new StringReader(@"{""input"" : ""value"", ""output"" : ""result""}"));

JsonWriter

2、Newtonsoft.Json.Linq
JObject
JObject jObject = JObject.Parse(objstring);

JObject obj = new JObject();
obj["data"] = 1;
string jsonstring = obj.ToString();

JArray
JArray jArray = JArray.Parse(jObject["data"].ToString());
foreach (var v in jArray){}

var value=jArray[a].ToString()

JArray array = new JArray();
array.Add("1");

JValue
JProperty

3、Newtonsoft.Json.Serialization

反序列化
object对象转为字符串
string datastring = JsonConvert.SerializeObject(result.data);
字符串转为JToken索引对象
JToken json = JValue.Parse(datastring);
取得属性
int id = (int)json["id"];
取得数组
JArray jarray = (JArray)json["jarray"];
foreach (dynamic arr in jarray)
int id = (int)arr["id"];
