Ignore property if it is an empty ('') string from Json/Api Response C#

Question

Below is the json response I have currently.

{
   firstName: "xyz",
   lastName: "efh",
   id: 123,
   key: ''
}

How to ignore a property if it is an empty string like key from the above response. I know how to ignore a a property when it is null but not when it is empty.

Your keys need to be enclosed in double quotes. And the empty value also needs to be in double quotes. — Palle Due

To ignore empty string use default value handling option and set property default value to empty string

[DefaultValue("")]
public string key { get; set; }

And in set JsonSerializerSettings as below

new JsonSerializerSettings 
          { DefaultValueHandling = DefaultValueHandling.Ignore }

You can create custom converter by extending Newtonsoft.Json.JsonConverter and override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
