Select Token C# Json array

Question

I have the code below and i want to select the child note when i am accessing 'a'. But string result is returning null when i select the 'character' node

JObject jObj = (JObject)JsonConvert.DeserializeObject(strJson);
Assert.IsTrue(response.IsSuccessStatusCode.Equals(true));
var a = (JArray)jObj["cast"];
string result = (string)a.SelectToken("character");

This is the JSON response i get from 'a':

{[
{
"character": "Eddard Stark",
"credit_id": "5256c8ad19c2956ff60478a6",
"id": 48,

Solution 1

First you have to create model class You can use http://json2csharp.com/, and deserialize it using Json.NET

use the following namespace

using Newtonsoft.Json;

model class and DeserializeObject method

        public class RootObject
    {
        public string character { get; set; }
        public string credit_id { get; set; }
        public int id { get; set; }
        public string name { get; set; }
        public string profile_path { get; set; }
        public int order { get; set; }
    }


var x =JsonConvert.DeserializeObject<List<RootObject>>(myjsondata);
var character = x[index].character;

Solution 2

Your JSON seems to be incorrect, you have to remove begin and end curly braces.

Correct JSON:

[{
    "character": "Eddard Stark",
    "credit_id": "5256c8ad19c2956ff60478a6",
    "id": 48,
    "name": "Sean Bean",
    "profile_path": "/iIxP2IzvcLgr5WaTBD4UfSqaV3q.jpg",
    "order": 0
}, {
    "character": "Jon Snow",
    "credit_id": "5256c8af19c2956ff6047af6",
    "id": 239019,
    "name": "Kit Harington",
    "profile_path": "/dwRmvQUkddCx6Xi7vDrdnQL4SJ0.jpg",
    "order": 0
}, {
    "character": "Robert Baratheon",
    "credit_id": "5256c8ad19c2956ff60478e2",
    "id": 13633,
    "name": "Mark Addy",
    "profile_path": "/tGWYaLPIGvPJiKx9KzTBMITo7uK.jpg",
    "order": 1
}, {
    "character": "Daenerys Targaryen",
    "credit_id": "5256c8af19c2956ff60479f6",
    "id": 1223786,
    "name": "Emilia Clarke",
    "profile_path": "/tB1nE2LJH81f5UMiGhKCSlaqsF1.jpg",
    "order": 1
}, {
    "character": "Tyrion Lannister",
    "credit_id": "5256c8b219c2956ff6047cd8",
    "id": 22970,
    "name": "Peter Dinklage",
    "profile_path": "/xuB7b4GbARu4HN6gq5zMqjGbkwF.jpg",
    "order": 2
}]

Equivalent Model class:

public class SampleClass
{
    public string character { get; set; }
    public string credit_id { get; set; }
    public int id { get; set; }
    public string name { get; set; }
    public string profile_path { get; set; }
    public int order { get; set; }
}

Deserialize using the below code:

It will give you List or Array of SampleClass object. You can use foreach loop or LINQ to get all the character field.

List<SampleClass> lsObj = JsonConvert.DeserializeObject<List<SampleClass>>(strJson);

    foreach(SampleClass obj in lsObj)
    {
        string character = obj.character;
    }
