How to deserialize JSON in C# - .NET | Microsoft Learn

A common way to deserialize JSON is to have (or create) a .NET class with properties and fields that represent one or more of the JSON properties. Then, to deserialize from a string or a file, call the JsonSerializer.Deserialize method.

You need to create a structure like this:

public class Friends
{

    public List<FacebookFriend> data {get; set;}
}

public class FacebookFriend
{

    public string id {get; set;}
    public string name {get; set;}
}

Then you should be able to do:

Friends facebookFriends = new JavaScriptSerializer().Deserialize<Friends>(result);

The names of my classes are just an example. You should use proper names.

Adding a sample test:

string json =
    @"{""data"":[{""id"":""518523721"",""name"":""ftyft""}, {""id"":""527032438"",""name"":""ftyftyf""}, {""id"":""527572047"",""name"":""ftgft""}, {""id"":""531141884"",""name"":""ftftft""}]}";

Friends facebookFriends = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<Friends>(json);

foreach(var item in facebookFriends.data)
{
    Console.WriteLine("id: {0}, name: {1}", item.id, item.name);
}

Produces:

id: 518523721, name: ftyft
id: 527032438, name: ftyftyf
id: 527572047, name: ftgft
id: 531141884, name: ftftft

Sometimes I prefer dynamic objects:

public JsonResult GetJson()
{
  string res;
  WebClient client = new WebClient();

  // Download string
  string value = client.DownloadString("https://api.instagram.com/v1/users/000000000/media/recent/?client_id=clientId");

  // Write values
  res = value;
  dynamic dyn = JsonConvert.DeserializeObject(res);
  var lstInstagramObjects = new List<InstagramModel>();

  foreach(var obj in dyn.data)
  {
    lstInstagramObjects.Add(new InstagramModel()
    {
      Link = (obj.link != null) ? obj.link.ToString() : "",
      VideoUrl = (obj.videos != null) ? obj.videos.standard_resolution.url.ToString() : "",
      CommentsCount = int.Parse(obj.comments.count.ToString()),
      LikesCount = int.Parse(obj.likes.count.ToString()),
      CreatedTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds((double.Parse(obj.created_time.ToString()))),
      ImageUrl = (obj.images != null) ? obj.images.standard_resolution.url.ToString() : "",
      User = new InstagramModel.UserAccount()
             {
               username = obj.user.username,
               website = obj.user.website,
               profile_picture = obj.user.profile_picture,
               full_name = obj.user.full_name,
               bio = obj.user.bio,
               id = obj.user.id
             }
    });
  }

  return Json(lstInstagramObjects, JsonRequestBehavior.AllowGet);
}

The problem is your JSON response is an object. You need to extract the data from d property.

Either working with Newtonsoft.Json.Linq to extract the data ind property:

Copyusing Newtonsoft.Json.Linq;

var dtoDirectiries = JObject.Parse(output)
    .SelectToken("d")
    .ToObject<List<Statuses>>();

Or create a Root class and deserialize as Root instance:

Copyvar dtoDirectiries = JsonConvert.DeserializeObject<Root>(output)
    .Data;

public class Root
{
    [JsonProperty("d")]
    public List<Statuses> Data { get; set; }    
}

I've checked many websites, they gave me a very broad understanding of deserializing JSON but I still haven't really managed to get it working since they're not really made for c# beginners.

Anyone know any good beginner links for this?

Currently using restsharp and json.net.

You want to write your own deserializer? Or you want to use one of the many existing libs?

2 of 3

It might be easier to understand how JSON deserialization works by looking at a simpler JSON library, like Tiny Json: https://github.com/zanders3/json/blob/master/src/JSONParser.cs At a high level, it's going to use reflection to go through the properties on the type (like in the ParseObject method). It will have some kind of strategy for mapping the JSON types to .NET primitive types (like a JSON number to a .NET int, long, double, etc.). Deserializing to a dynamic or System.Object type will generally map a JSON array something like List (JArray in Json.NET), and a JSON object to something like Dictionary (JObject in Json.NET).

r/csharp on Reddit: Is there a easy way to deserialize JSON to a struct?

May 9, 2024 -

I'm working on a side project right now where I have a class containing two structs and a string as attributes. I need to read values from a JSON file on the computer, then fill the structs and the string with the values in the JSON.

I deserialized JSON before but was always using classes with primitive-type attributes. It's the first time I need to deserialize JSON to fill a struct. I tried to do the same as with classes, suing JsonProperty annotations and calling JsonConvert.DeserializeObject<T>(json) in my code, but without any success.

Any suggestion online seems to advise creating a custom JsonConverter and it doesn't look really easy. I found one solution using a Dictionary, another using classes, but doesn't seem to be anything using structs. Is that really impossible in C#?

Thanks for any input, it's very appreciated!

EDIT: Here's the JSON that is loaded into the application:

{ "time_prices": { "hour": 19.99, "day": 49.99, "week": 249.99, "month": 999.99 }, "distance_prices": { "free_km": 500, "price_per_km": 0.18 }, "fuel_consumption": 37}

Here's the class representing the JSON; https://dotnetfiddle.net/JOwQtT

The goal is to load that JSON into the class so the values could be accessed to make some price calculations. The values will never be modified. I think they could probably be marked as readonly since once initialized, they will never change.

If you're not doing something weird with the structs, it should be fine. Structs should just be containers for primitives anyway. So you're just adding brackets to the json.

I'm not sure the exact solution for you but I am confident it is possible because I researched this just a few weeks back. You may need to investigate the constructor. Also do your properties all have getters/setters?
