Deserialize Json array of array in c#

Question

I am new to c# don't know how to get a JSON array of array stored in a 2d array. I am having a JSON file with students marks like

[
    [10,5,4],
    [9,6,3]
]

and out of this I am using this code but getting error out at JArray

JArray a = JArray.Parse(json);

I have tried some other approaches as well but nothing helped basically what I want to do is want to create a boolean 2D array which will be populated on the basis of the above JSON record and for that purpose I want to populate the array with JSON content.

Answer 1

With the following valid JSON

{ "data" : [
    [10,5,4],
    [9,6,3]
]
}

The following class was used to hold the parsed data

public class RootObject {
    public IList<IList<int>> data { get; set; }
}

which can be parsed using Json.Net

var root = JsonConvert.DeserializeObject<RoootObject>(json);

and the content accessed

var x1 = root.data[0][1]; // 5
var x2 = root.data[1][1]; // 6
