Newtonsoft Json how to only take Value section-CodePudding

On my API side, I use JsonConvert.SerializeObject() to set it to a string. This is the output from my API:

{"ContentType":null,"SerializerSettings":null,"StatusCode":null,"Value":{"draw":1,"recordsTotal":0,"recordsFiltered":0,"data":[],"order":null,"orderdir":null}}

This is what the API looks like:

[HttpPost("Preview")]
public JsonResult Preview([FromBody]AnnouncementAccessPreviewRequestViewModel svm)
{
    ApiResponseViewModel arvm = new ApiResponseViewModel();
    var res = announcementData.Preview(svm.SearchViewModel, svm.TenantId);
    arvm.IsSuccessful = true;
    arvm.Message = null;
    arvm.Output = JsonConvert.SerializeObject(res);
    return Json(arvm);
}

arvm.Output is a string

How can I only take the Value section from the output?

That's how I solved it when I had this problem. private YourModel GetJsonObject()

   var parsedObject = JObject.Parse(resultContent);
   string p = parsedObject.ToString();
   if (p.Contains("Succes"))
      {
       string popupJson = JObject.Parse(parsedObject["data"].ToString()).ToString();
       YourModel= JsonConvert.DeserializeObject<YourModel>(popupJson);
       return YourModel;
       }

There is a side way to get this model from https://json2csharp.com/.

CodePudding user response：

you can try this

   var output=JObject.Parse(json);
   
   Value value=output["Value"].ToObject<Value>();

class

public class Value
{
    public int draw { get; set; }
    public int recordsTotal { get; set; }
    public int recordsFiltered { get; set; }
    public List<object> data { get; set; }
    public object order { get; set; }
    public string orderdir { get; set; }
}

or if you can change Api

public JsonResult Preview([FromBody]AnnouncementAccessPreviewRequestViewModel svm)
{
       var res = announcementData.Preview(svm.SearchViewModel, svm.TenantId);
    
    var output = JsonConvert.SerializeObject(res);
    return Json(output);
}

but the right way is

public IActionResult Preview([FromBody]AnnouncementAccessPreviewRequestViewModel svm)
{
    return announcementData.Preview(svm.SearchViewModel, svm.TenantId);
}

in this case you don't need to serialize or deserialize
