I once retrieve a specific value from JSON formatted text before but now my approach seemed to be not working. My string sp value is receiving null value. I tried to look for the same question with an answer here on codeproject but none of them works.

I was trying to get the "id" from

{"data": [
    {
      "id": 109993,
      "member_id": 378832,
      "issuer_sign": 9,
      "ta_id": 96122,
      "endorsement": null,
      "title": "Member"
      
}
]
}

What I have tried:

dynamic obj = JsonConvert.DeserializeObject(str);
     string sp = Convert.ToString(obj.id);

You need to create a custom object that includes the same signature as your JSON. Something like-

public class MyData
{
    public int id { get; set; }
    public int member_id { get; set; }
    public int issuer_sign { get; set; }
    public int ta_id { get; set; }
    public string endorsement { get; set; }
    public string title { get; set; }
}

var data = JsonConvert.DeserializeObject<MyData>(jsonString);

And then deserialize your JSON with this object. Please read this for more reference-

Your json is a property called "data" which is an array of objects, and in your case there is only one item in the array. If you wanted to get the id of the first item in the data array you would do this

string sp = Convert.ToString(obj.data[0].id);

However if you expect more items to be in data then you'd need to loop to find the one you wanted, or to process them all, whichever meets your requirements.
