How to deserialize a json array more simply?

Question

Is there some way to take only the data from the dataset and ignore the start array 'result' ?

{
    "result": [
        "",
        {
            "dataset": [
                {
                    "idSottogruppo": "7",
                    "Sottogruppo": "Distribuzione Ausiliaria"
                }, {
                    "idSottogruppo": "6",
                    "Sottogruppo": "Distribuzione Motore"
                }, {
                    "idSottogruppo": "8",
                    "Sottogruppo": "Filtri"
                }, {
                    "idSottogruppo": "39",
                    "Sottogruppo": "Motore"
                }
            ]
        }
    ]
}

That's how I did it and it works, I just want to do less code if it's possible as all API methods have the same JSON format.

My Code:

public class OE_GetActiveSubGroupsResultDTO
{
    public List<OE_GetSubActiveGroupsListDTO> Result { get; set; }
}

public class OE_GetActiveSubGroupsListDTO
{
    public List<OE_GetActiveSubGroupsDTO> Dataset { get; set; }
}

public class OE_GetActiveSubGroupsDTO
{
    public string idSottogruppo { get; set; }
    public string Sottogruppo { get; set; }
}

public ActionResult ProcessSpareParts(CarViewModel vm)
{
    OE_GetActiveItemsResultDTO activeItemsResultDeserialize = JsonConvert.DeserializeObject<OE_GetActiveItemsResultDTO>(GetActiveSubGroups);
                            
    foreach(var activeItemsResult in activeItemsResultDeserialize.Result[1].Dataset)
    {
        OE_GetActiveItemsDTO activeItems = new JavaScriptSerializer().Deserialize<OE_GetActiveItemsDTO>(activeItemsResult .ToString());    
        ...
    }
}

Here is the one line code

Note: this code doesn't do any validation to Input data. This code works if the format of the json doesn't change

string json = File.ReadAllText("json1.json");

var result = JObject.Parse(json)["result"][0]
                    .Next["dataset"]
                    .Select(x => new OE_GetActiveSubGroupsDTO 
                    { 
                            idSottogruppo = x["idSottogruppo"].ToString(), 
                            Sottogruppo = x["Sottogruppo"].ToString() 
                    });
