ignore null values while deserializing JSON in newtonsoft

Question

I have following json coming from server

{
 "contactList":[{

      "contactName":"Jhon",
      "address":null,
      "phone":null,
      "contactId":99932

}]

}

now when i am deserializing using JsonConvert.DeserializeObject<Response>(content) i want following output

{
     "contactList":[{

          "contactName":"Jhon",
          "contactId":99932

    }]

    }

i tried following code but its not working

 JsonSerializerSettings jsonSettings = new JsonSerializerSettings
                    {
                        NullValueHandling = NullValueHandling.Ignore,
                        MissingMemberHandling = MissingMemberHandling.Ignore
                    };

this is my Contact model

public class Contact 
    {
        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public String address { set; get; }

       [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
         public String phone { set; get; }

        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
         public String name { set; get; }

        [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
         public String id { set; get; }
  }

model of Response

     [JsonObject(MemberSerialization = MemberSerialization.OptIn)]
 public class Response 
    {
         [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
        public IList<SignodeMSA.Model.Master.Contact> contactsList { get; }
  }

and i am deserializing after fetching it from server

  Response responseData = await Task.Run(() => JsonConvert.DeserializeObject<Response>(content, jsonSettings));

The json settings must work, how do you use them? Post the code where you serialize the data. — Gusman, May 02 '17 at 20:03
@SiyavashHamdi Json.net has the ability to not to write out null values if its told to do so. — Gusman, May 02 '17 at 20:04
You are *deserializing* to the statically typed `Contact` which has properties `phone` and `id` those are part of your .NET class. They can't disappear. `NullValueHandling.Ignore` affects *serialization* only. — Matt Burland, May 02 '17 at 20:17

I think you need manually delete that properties from json string.

Maybe like this : How do I remove all null and empty string values from a json object?
