How to deserialize dictionary using Newtonsoft [Answered]

I have a Json file with a bunch of pokemon data. I am having trouble deserializing the information. The console is running and showing no errors, but it exits out immediately. This is not a Console.ReadLine() issue because commenting out the: Pokemon pkmn = JsonConvert.DeserializeObject<Pokemon>(jsonFile); makes the console stay. I also think I have an error with how I am storing the data. I am not sure how to access a specific item.

// Json Template
/*
{
"id": 1,

"name": {
"english": "Bulbasaur",
"japanese": "フシギダネ",
"chinese": "妙蛙种子",
"french": "Bulbizarre"},

"type": [
"Grass",
"Poison"],

"stats": {
"HP": 45,
"Attack": 49,
"Defense": 49,
"Sp. Attack": 65,
"Sp. Defense": 65,
"Speed": 45}
}
*/

//Libraries
using Newtonsoft.Json;


//1. Get the file from the path and read it!
string path = @"C:\Users\c e r e s\Desktop\Pokemon\pokedex.json";
string jsonFile = File.ReadAllText(path);

//2. Access Pokemon Class and deserialize:
Pokemon pkmn = JsonConvert.DeserializeObject<Pokemon>(jsonFile);

//3. Iterate values from the array
Console.WriteLine(pkmn.id);
Console.ReadLine();

//Storage structure
public class Pokemon { 
    public int id { get; set; }
    public Dictionary<string, int> name { get; set; }
    public string[] type { get; set; }
    public Dictionary<string, int> stats { get; set; }
};

// Json Template
/*
{
"id": 1,

"name": {
"english": "Bulbasaur",
"japanese": "フシギダネ",
"chinese": "妙蛙种子",
"french": "Bulbizarre"},

"type": [
"Grass",

"stats": {
"HP": 45,
"Attack": 49,
"Defense": 49,
"Sp. Attack": 65,
"Sp. Defense": 65,

}

name is not a Dictionary<string, int>

Cvfe Cvt ᵖᵘʳʳOP•3y ago

Thank you, what data structure is it?

ero•3y ago

what pairs are in the name element?

Cvfe Cvt ᵖᵘʳʳOP•3y ago

I am unsure of what you mean. I'm not familiar with C# dictionaries, only python. It is my understanding that the language is the key and the pokemon in the value in the name element.

pip•3y ago

what you should do to test this is make a dictionary, then serialize it. see what comes out. i'm thinking that you may have to explicitly specify {"key" : "english", "value":"Bulbasaur"} but that's just a guess

ero•3y ago

no even python has types what type is "english"

Cvfe Cvt ᵖᵘʳʳOP•3y ago

Oh, I suppose a string.

ero•3y ago

and what type is "Bulbasaur"

Cvfe Cvt ᵖᵘʳʳOP•3y ago

A string as well.

ero•3y ago

so what should be the key and value types in the name Dictionary?

Cvfe Cvt ᵖᵘʳʳOP•3y ago

Oh! I didn't realize that was still set to int. I had changed everything to string earlier to test.

ero•3y ago

there you go

Cvfe Cvt ᵖᵘʳʳOP•3y ago

It still doesn't run though lol.

ero•3y ago

any errors? oh, jsonconvert 🤢

Cvfe Cvt ᵖᵘʳʳOP•3y ago

I apologize for the image. VS wasn't showing an error. Had to print screen the console. I didn't realize the error until now

ero•3y ago

can you show your full code? but if possible, just don't use newtonsoft

The entire code is at the top. I'll try System.Text.Json.JsonSerializer.Deserialize<Pokemon>(json); Newton was what I found online. How did you color your blocks?
