Using a JSON array received as a string

Question

I'm receiving a string, output, that looks like this:

{family_name:XXX, given_name:XXX, locale:en, name:XXX, picture:XXX, profile:XXX, sub:XXX}

I'd like to get some of these values and store them in variables, but since it's a string I cant use indexing (I would've just used var x = output[0] etc)

How would I get a hold of these values?

Thanks in advance

You can use `json.net` to deserialize the json string into an object (the easy way), or the classes in `Newtonsoft.Json.linq` to parse it manually. — Zohar Peled, Dec 27 '18 at 13:54
You will have to de-serialize the string using a json parser such as json.net or javascriptserializer provided with .net framework. — shahkalpesh, Dec 27 '18 at 13:55
A JSON string would have quotes around the names and values. Have you removed those quotes or are they not there? http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf This question covers answers regarding C# https://stackoverflow.com/q/6620165/125981 — Mark Schultheiss, Dec 27 '18 at 14:07

The structure of the string is a JSON-object. Therefore, you must handle it as a JSON-object. First parse it to JSON. eg. like this:

JObject json = JObject.Parse(YOUR_STRING);

And now to get the given value you wish, for instance family_name you can say:

string name = (string) json["family_name"];

I would recomend Json.Net.

Parse your string to json, and create a model that can hold those JSON values as

public class Person
{
    public string family_name {get;set}
    public string given_name {get;set;}
    public List<string> siblings{get;set;}
}

(This could be done with https://quicktype.io/csharp/ or manually)

Then:

string json = @"{
  'family_name': 'Foo',
  'given_name': 'Bar',
  'siblings': [
    'Jhon',
    'Doe'
  ]
}";

Person person = JsonConvert.Deserialize<Person>(json);

string familyName = person.family_name;
//Foo
