dynamic c# ValueKind = Object

Question

As i'm trying to access object values using JsonSerializer.Deserialize using debugger.

Here is my result which i'm having below.

  OtpData = ValueKind = Object : "{
        "OTP":"3245234",
        "UserName":"mohit840",
        "type":"SuperAdmin"
    }"

As i try to access it using var Data = JsonSerializer.Deserialize(OtpData) it gives me following error below.

How can i access the inside and get values of the following object.

"OTP":"3245234",
        "UserName":"mohit840",
        "type":"SuperAdmin"

Update :

        [AllowAnonymous]
        [HttpPost("ValidateOTP")]
        public IActionResult ValidOTP(dynamic OtpData)
        {
            bool Result = false;
            var Data = JsonSerializer.Deserialize(OtpData);            
            if (OtpData.type == "SuperAdmin")
            {
                Users _Users = _Context.Users.FirstOrDefault(j => j.Username == "");
                if (_Users != null)
                {
                    _Users.OTP = OtpData.OTP;                    
                    _Users.VerififedOTP = true;
                    _Context.SaveChanges();
                    Result = true;
                }
            }
            else
            {
                Staff _Staff = _Context.Staffs.FirstOrDefault(j => j.Username == "");
                if (_Staff != null)
                {
                    _Staff.OTP = OtpData.OTP;                    
                    _Staff.VerififedOTP = true;
                    _Context.SaveChanges();
                    Result = true;
                }
            }

            return Ok(new { Result = Result });
        } 

Update 2: As i'm posting this by Postman application.

{
    "OTP":"3245234",
    "UserName":"mohit840",
    "type":"SuperAdmin"
}

Answer 1

From new release of Asp.net Core 3.0 Microsoft has come with System.Text.Json which introduce new JsonElement ValueKind so ValueKind is from System.Text.Json library and JsonConvert is from Newtonsoft library.

Resolution :-

it is possible that you have mixed both the library while Serializing the object you may have used Newtonsoft.Json and while Deserilizing you may have used System.Text.Json or vice versa.

Answer 2

Found a real way to tackle it i have used JObject instead of dynamic. Here is a sample below.

public ResponseWrapper<GenericResponseModel> PostServiceStreams(JObject jObject)
{
  return ResponseService.ReturnResponse(() =>
  {
     return new GenericResponseModel(true, string.Empty,database.MarkedIssues.Select(j => j).ToList().Select(i => i.MapMarkedIssuesModels()).ToList());
  }, Request);
}

As you can get values like this below.

{
    "OTP":"3245234",
    "UserName":"mohit840",
    "type":"SuperAdmin"
}

This is a object which i'm sending. Here is the receiving method.

jObject["OTP"].ToString();

public async Task<dynamic> PostAsync([FromBody] Object post)
{
     var data = JsonConvert.DeserializeObject<dynamic>(post.ToString());
