Json Deserializer Returning Null Values

json deserialization returns null

You have an extra level of nesting {"cat": { /* CategoryVM contents */ }} that is not reflected in your data model. The easiest way to account for this is to deserialize to a wrapper object with a public CategoryVM cat property, which could be an anonymous type object:

var c = JsonConvert.DeserializeAnonymousType(cat, new { cat = default(CategoryVM) })
    .cat.category;

Json Deserialize Object returns null when called

I fixed it and just in case somebody faced the same problem I'd like to post a solution on how I managed to solve it. Basically what I did was adding this class that appends additional settings onto a serializer:

 internal static class Converter
    {
        public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
        {
            MetadataPropertyHandling = MetadataPropertyHandling.Ignore,
            DateParseHandling = DateParseHandling.None,
            Converters =
            {
                new IsoDateTimeConverter { DateTimeStyles = DateTimeStyles.AssumeUniversal }
            },
        };
    }

and then adding it as a parameter to the DeserializeObject method such as:

User user= JsonConvert.DeserializeObject<User>(json, Converter.Settings);

I hope it helps somebody.

JsonDeserialize is returning null values after attempting to bind to model

First, the name of your properties are not correct with json names; they should be same or you have to use a jsonProperty attribute. And the main class name is not correct; your main class is should be a class that includes your sub class like 'Payee', 'Address' and rest , please see my codes, i fixed a bit.

    public class PayInfo
    {

        public Payee Payee { get; set; }
        public Payment Payment { get; set; }
        public List<Remittance> Remittance { get; set; }

    }
    public class Payee
    {
        [JsonProperty("Name")]
        public string PayeeName { get; set; }

        [JsonProperty("Fax")]
        public string PayeeFax { get; set; }

        [JsonProperty("Phone")]
        public string PayeePhone { get; set; }

        public Address Address { get; set; }

        public string Attention { get; set; }
        public string SubmissionDate { get; set; }
        public string PaymentExp { get; set; }
    }


    public class Payment
    {
        public string PAN { get; set; }
        public string CVV { get; set; }
        public string Exp { get; set; }


    }
    public class Address
    {

        public string Address1 { get; set; }
        public string Address2 { get; set; }
        public string City { get; set; }
        public string StateOrProvince { get; set; }
        public string Zip { get; set; }

    }
    public class Remittance
    {
        public string PayorName { get; set; }
        public string PayorId { get; set; }
        public string InvoiceNo { get; set; }
        public string Description { get; set; }
        public string Amount { get; set; }
    }

And you can modify your method like this as using list instead of array , will be easier.

     public static List<PayInfo> ReadJson()
    {
        // read file into a string and deserialize JSON to a type
        var payInfoData1 = JsonConvert.DeserializeObject<List<PayInfo>>(File.ReadAllText(@"JsonData\sample.json"));
        // deserialize JSON directly from a file
        using (StreamReader file = File.OpenText(@"JsonData\sample.json"))
        {
            JsonSerializer serializer = new JsonSerializer();
            // PayInfo[] payInfoData = (PayInfo[])serializer.Deserialize(file, typeof(PayInfo[]));
            payInfoData1 = (List<PayInfo>)serializer.Deserialize(file, typeof(List<PayInfo>));
            return payInfoData1;
        }
    }

C# JsonConvert.DeserializeObject returning null values for a json array of objects

When you do

JsonConvert.DeserializeObject<List<Model.AuxilioEmergencial>>(restResponse.Content);

You're telling the deserializer that you want a List, where every element is of type AuxilioEmergencial.

Your class AuxilioEmergencial has 1 property auxilio, which means every object in the JSON array has to have that property to be properly deserialized. E.g.:

[
  {
    "auxilio": {
      "id ": 1,
      "mesDisponibilizacao": "06/2020",
      ...
    }
  },
  {
    "auxilio": {
      ...
    }
  }
]

What you actually want is:

JsonConvert.DeserializeObject<List<Model.Auxilio>>(restResponse.Content);

Returning null value in JSON Deserialization

try this, it was tested in visual studio

var jsonParsed = JObject.Parse(json); 

List<EmployeeMasterData> employeeMasterData  = jsonParsed["root"]["EmployeeMaster"]
["EmployeeMasterData"].Select(x => AddItems(x)).ToList();

public static EmployeeMasterData AddItems(JToken jt)
{
    var emd = new EmployeeMasterData();
    foreach (var element in ((JObject)jt).Properties())
    {
        if (element.Name == "BasicDetails")
            emd.BasicDetails = element.Value.ToObject<BasicDetails>();
        if (element.Name == "DependentDetails")
            emd.DependentDetails = element.Value.ToObject<DependentDetails>();
        if (element.Name == "ContactDetails")
            emd.ContactDetails = element.Value.ToObject<ContactDetails>();
    }
    return emd;
}
