Check this:

public class Root
{
    public List? Positions { get; set; }
}

public class Position
{
    [JsonProperty("SerialNumber", NullValueHandling = NullValueHandling.Ignore)] 
    public string SerialNumber { get; set; }

    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    public int? position { get; set; }

    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    public int? result { get; set; }
}

var root = new Root
{
    Positions = new List
    {
        new Position
        {
            SerialNumber = "34543545"
        },
        new Position
        {
            position = 1,
            result = 0
        },
        new Position
        {
            position = 2,
            result = 0
        },
        new Position
        {
            position = 3,
            result = 0
        }
    }
};
var results = new List { root };
string json = JsonConvert.SerializeObject(results, Formatting.Indented);
Console.WriteLine(json);

Hi Jignesh,

Already I tired the above but am getting result like below but i want all the content under Positions

[
{
"SerialNumber ": "34543545",
"positions": [
{
"position": 1,
"result": 0
},
{
"position": 2,
"result": 1
},
{
"position": 3,
"result": 0
}
]
}
]

But i want the format like below

[{
   "Positions": [
   {
           "panelSn": "34543545"
       },
       {
           "position": 1,
           "result": 0
       },
       {
           "position": 2,
           "result": 0
       },
       {
           "position": 3,
           "result": 0
       }
   ]
}]

Hello,

Please try this one,

public class Root
{
    public string? SerialNumber { get; set; }
    public List? Positions { get; set; }
}

public class Position
{
        
  public int? position { get; set; }
  public int? result { get; set; }
}
