❔ Get only values when deserialize json

Hi, it's possible to deserialize something like this with only values?

"genres": {
    "Action": "Action",
    "Adventure": "Aventure",
    "Drama": "Drame",
    "Fantasy": "Fantastique"
},

"genres": {
    "Action": "Action",
    "Adventure": "Aventure",
    "Drama": "Drame",
    "Fantasy": "Fantastique"
},

I would like something like this instead of a Dictionary:

[JsonPropertyName("genres")]
public List<string> Genres { get; set; }

[JsonPropertyName("genres")]
public List<string> Genres { get; set; }

How do you want this to work?

Why wouldn't you just deserialize then convert it to list?

I'm building an api wrapper. So I just use

[JsonPropertyName("genres")]
public Dictionary<string, string> Genres { get; set; }

[JsonPropertyName("genres")]
public Dictionary<string, string> Genres { get; set; }

And I add some method to get a list?

It's not clear how you want to get a list from this because the json is a dictionary You have "Fantasy": "Fantastique" which isn't obvious how it should become an element in a list.

Yes but I only need the values.

Then deserialize into a dictionary and use the Values of the dictionary.

Something like this?

[JsonPropertyName("genres")]
private Dictionary<string, string> _Genres { get; set; }

public List<string> Genres => _Genres.Values.ToList();

[JsonPropertyName("genres")]
private Dictionary<string, string> _Genres { get; set; }

public List<string> Genres => _Genres.Values.ToList();

yeah Although personally I'd use IReadOnlyCollection<string> and not List<string>

Rtransat•12mo ago

I would like to deserialize _Genres with a private visibility because the users of the lib doesn't need to use _Genres. It's possible? Why not IEnumerable<string>?

Wouldn't a DTO to contract map be better in this situation?

Thinker•12mo ago

might be Corrected myself, having a count is probably beneficial
