What am I doing wrong with this deserialized data?

When I run my program i'm only getting nulls and zero's when trying to access card prices from the json provided. Anyone have an idea on what I did wrong in my code?

Json Used
https://db.ygoprodeck.com/api/v7/cardinfo.php?name=Tornado%Dragon

(reposted my question with less clutter)

well cardmarket_price isnt on the root of the json, if you deserialized right, you access it like this

price.data[0].card_prices[0].cardmarket_price

you can let a site like https://json2csharp.com/ generate classes out of the json for you

That worked, had no clue it had to be typed down that way (or why [0] is needed).

because data and card_prices are arrays

i see i see thanks, now to see if i can find more information about this. 🙂
