Question

Im having trouble in parsin JSON in C#. I want to parse this Json Format.

{
"data": 
  [
    {
        "id": 3,
        "code": "‎0000004", 
    }
  ]  
}

Here is my code in C#.

 public Data data { get; set; } 

 public class Data
 {
     public string id { get; set; }
     public string code { get; set; }
 }

The JSON shown is an object that has (as data) an array of elements that have an id and code, so:

public class SomeRoot {
   public List<Data> data {get;} = new List<Data>();
}

and deserialize a SomeRoot and you should be fine:

var root = JsonConvert.DeserializeObject<SomeRoot>(json);
var obj = root.data[0];
Console.WriteLine(obj.id);
Console.WriteLine(obj.code);

You are missing an essential part, the outer object. Also, the data is an array:

public class RootObject
{
    public Data[] data { get; set; } 
}

RootObject r = JsonConvert.DeserializeObject<RootObject>(json);

Next time, follow the steps as outlined in Easiest way to parse JSON response. It will help you generate the correct class.

It should be :

public class Data
{
    public int id { get; set; }
    public string code { get; set; }
}

public class RootObject
{
    public List<Data> data { get; set; }
}

What changed...? – Patrick Hofman Apr 09 '18 at 09:39
Yes, I think we add answers the same time :)) – Rai Vu Apr 09 '18 at 09:50
That doesn't matter. What does matter that you didn't state what the problem is and just dump some code. – Patrick Hofman Apr 09 '18 at 09:51
