How to parse complex json to c# .net classes

Question

my json is as given below. i need to convert it into c# class. Please note all values will be different in actual scenario.

{
  'aa-AA': {
    lanCODE: 'aa-AA',
    genNames: {
      female: ['Wavenet'],
      male: ['Bavenet', 'Bavenet'],
    },
    default: 'Wavenet',
    systemLocale: ['ara', 'aru', 'are', 'aro', 'arh', 'arm', 'arq', 'ark'],
    name: 'xxxx',
  },
  'aa-AA': {
    lanCODE: 'aa-AA',
    genNames: {
      female: ['Wavenet'],
      male: ['Bavenet', 'Bavenet'],
    },
    default: 'Wavenet',
    systemLocale: ['ara', 'aru', 'are', 'aro', 'arh', 'arm', 'arq', 'ark'],
    name: 'xxxx',
  },
  'aa-AA': {
    lanCODE: 'aa-AA',
    genNames: {
      female: ['Wavenet'],
      male: ['Bavenet', 'Bavenet'],
    },
    default: 'Wavenet',
    systemLocale: ['ara', 'aru', 'are', 'aro', 'arh', 'arm', 'arq', 'ark'],
    name: 'xxxx',
  }
 }

Does the complexity of the JSON cames from the fact that it's ill formated and not valid ? — Self, Apr 26 '21 at 14:16

"You need" is different than what you have tried. Please post what you have tried in c# and the challenges it has presented to to so we may help you fix it. — Mark Schultheiss, Apr 26 '21 at 14:20
Format error are : using single quote `'` instead of double quote, Property name must be double quoted `"`. Trailling comma are illegal ([1,2,3 **,** ]=> illegal) — Self, Apr 26 '21 at 14:26
step 1: make sure your JSON is valid. step 2: ***write at least some code yourself***. step 3: ask again when you have a _specific_ problem, instead of a generic task that's been asked and answered thousands of times before. — Franz Gleichmann, Apr 26 '21 at 14:28
And multiple properties named `"aa-AA"`, while it's legal (https://stackoverflow.com/questions/5306741/do-json-keys-need-to-be-unique). It's undefined behavior, where the last properties will eraze the previous value. — Self, Apr 26 '21 at 14:29

The initial property is almost certainly meant to be a dictionary key, so I would go with something like this:

public class Language
{
    [JsonProperty("lanCODE")]
    public string LanguageCode { get; set; }
    
    public string Default { get; set; }

    public List<string> SystemLocale { get; set; }

    public GenNames GenNames { get; set; }
}

public class GenNames
{
    public List<string> Female { get; set; }
    public List<string> Male { get; set; }
}

And deserialise like this:

var languages = JsonConvert.DeserializeObject<Dictionary<string, Language>>(json);
