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 }

public class Sample 
{
    [DataMember(EmitDefaultValue = false, IsRequired = false)]
    public string Test { get; set; }
}

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