Yes  Json Net is what you need  You basically want to deserialize a Json string into an array of objects   See their examples   string myJsonString          Name    Apple      Expiry      Date 1230375600000 1300         Price   3 99     Sizes          Small        Medium        Large              Deserializes the string into a Product object Product myProduct   JsonConvert DeserializeObject lt Product gt  myJsonString

Old question but worth adding an answer if using  NET Core 3 0 or later  JSON serialization deserialization is built into the framework  System Text Json   so you don t have to use third party libraries any more  Here s an example based off the top answer given by  Icarus  using System  using System Collections Generic   namespace ConsoleApp       class Program               static void Main string   args                        var json        Name     John Smith      Age   35      Name     Pablo Perez      Age   34                     use the built in Json deserializer to convert the string to a list of Person objects             var people   System Text Json JsonSerializer Deserialize lt List lt Person gt  gt  json                foreach  var person in people                                Console WriteLine person Name     is     person Age     years old                                      public class Person                       public int Age   get  set                public string Name   get  set

just take the string and use the JavaScriptSerializer to deserialize it into a native object  For example  having this json   string json      Name  John Simith  Age 35   Name  Pablo Perez  Age 34        You d need to create a C  class called  for example  Person defined as so   public class Person    public int Age  get set    public string Name  get set       You can now deserialize the JSON string into an array of Person by doing   JavaScriptSerializer js   new JavaScriptSerializer    Person    persons    js Deserialize lt Person   gt  json     Here s a link to JavaScriptSerializer documentation   Note  my code above was not tested but that s the idea Tested it  Unless you are doing something  exotic   you should be fine using the JavascriptSerializer

using Newtonsoft Json    Install this class in package console  This class works fine in all  NET Versions  for example in my project  I have  DNX 4 5 1 and DNX CORE 5 0 and everything works   Firstly before JSON deserialization  you need to declare a class to read normally and store some data somewhere This is my class   public class ToDoItem       public string text   get  set        public string complete   get  set        public string delete   get  set        public string username   get  set        public string user password   get  set        public string eventID   get  set        In HttpContent section where you requesting data by GET request for example   HttpContent content   response Content  string mycontent   await content ReadAsStringAsync      deserialization in items ToDoItem   items   JsonConvert DeserializeObject lt ToDoItem   gt  mycontent
