Simple use of Json data parsing, json data parsing

Simply remember the simple and practical Json parsing:

Scenario: Json data uploaded from the background to the client, similar:

string jsonObject="{'Name':'Jack','Age':25}";string jsonArray = "[{'Name':'Jhon','Age':23},{'Name':'Jack','Age':25}]";      

The client can define a class. The attributes in the class correspond to the corresponding fields in the data.

class Student{    public string Name { get; set; }    public int Age { get; set; }}

Add a reference to Newtonsoft. Json using the Nuget package, and add the using Newtonsoft. Json. Linq; namespace.

Create a JToken object and parse the above string:

 JToken jtoken = JToken.Parse(jsonObject); JToken jtoken2=JToken.Parse(jsonArray);

Then you can convert the data to the corresponding object:

if (jtoken1 is JObject) {       Student s=jtoken.ToObject<Student>();       Console.WriteLine(s.Name);       Console.WriteLine(s.Age); }if (jtoken2 is JArray){    List<Student> students = jtoken2.ToObject<List<Student>>();    foreach (var student in students)    {        Console.WriteLine(string.Format("Name:{0}\tAge:{1}", student.Name, student.Age));    }}

A Simple Method for parsing data :)
