Who can give an example of json parsing in C#?

Question

JSON

I have been struggling in c # with json for several days now. Working with json or xml in delphi is very easy compared to C#. I rummaged through about a hundred articles and forums on working with json in C #, but they contain something like this:

This picture also applies to the documentation of libraries for working with json.
Who can provide minimal C# code? You need to enter values ​​with title and url in the ListBox.

{
  "response":{
  "count":198,
  "items":[
  {
    "id":340125039,
    "owner_id":34254853,
    "artist":"IOWA",
    "title":"Маршрутка",
    "duration":190,
    "url":"http:\/\/cs7-5v4.vk-cdn.net\/p12\/630de313d73392.mp3?extra=fNremCtKgl4pnCbyZ0q-LOBIfvRoUf5QGo8oWwYrOCza6AlSUOdYIImUideFd3hpPa325ckSD_c3zQ5FNluMS80lrSJiM6FC",
    "genre_id":9
  },
  {
    "id":340120602,
    "owner_id":34254853,
    "artist":"Stromae",
    "title":"Tous Les Memes",
    "duration":168,
    "url":"http:\/\/cs7-1v4.vk-cdn.net\/p18\/600b1a66ef64d6.mp3?extra=GNP79R4nHR39dY50YJ_ddDxEuX6SQcxtG3nCgzI0LdvxoaLh5lQ2qZqqpABCqPoXOISyNzWOqMZx4_nTL3bQ31i57z-UXl4V",
    "lyrics_id":99395752

  }
  ]
  }
}

PS: Of course, you can make it on delphi dll, which will process json, then connect this dll to a project in C #, but this is at worst, of course, since I do not consider this method correct.

Answer 1

Here is an example very similar to yours:
stackoverflow.com/questions/13469666/how-to-parse-...
Used by LitJson. Essence: start classes for serialization, in them you do get-ers on fields named the same as json fields. All. In the example, the link even has an array.
Slightly more difficult - JBoy. You can also use it, the example is also easy to google.

Answer 2

internal static class Serializer
    {
        internal static void Serialize<T>(this T arg, string fileName)
        {
            string res = JsonConvert.SerializeObject(arg, Formatting.Indented);
            File.WriteAllText(fileName,res);
        }

        internal static T Deserialize<T>(string fileName)
        {
            string json = File.ReadAllText(fileName);
            T res = JsonConvert.DeserializeObject<T>(json);
            return res;
        }
    }

This class serializes/deserializes objects.

public class Item 
{
...
public string title{get; set;}
public string url{get;set;}
...
}

This is a single entry class. For serialization, use auto-properties (the same get; set;), be sure to public.

public class Response
{
public int count{get;set;}
public List<Item> items{get; set;}
}

To get data use code like

string pathToFIle = @"C:\temp\anyFile";
Response response = Serializer.Deserialize<Response>(pathToFile);
String[] titles = response.items.Select(item => item.title).ToArray(); // Массив названий
String[] urls = response.items.Select(item => item.url)ToArray(); // Массив адресов

library: newtonsoft.json.dll
If necessary, I can throw off a ready-made example (is there a personal on the toaster?).
