C# Ignore empty Prop in Json

Question

Hi
I want to the empty property in my Json to not show up
Current output
{"fields":{"sum":"Test","pro":{"ke":"T"},"itp":{"id":"10"},"cust":{"id":"13"},"cust7":{}}}

Expected
{"fields":{"sum":"Test","pro":{"ke":"T"},"itp":{"id":"10"},"cust":{"id":"13"}}}

I tried things as suggested here...

My Code

 public static string JiraStructureForCreate(Era eraRequest)
        {
            var tudhjs = new
            {
                fields = new
                {
                    sum = "st",
                    pro = new
                    {
                        ke = "T"
                    },
                    itp = new
                    {
                        id = "35"
                    },
                    cust = new
                    {
                        id = "23"
                    },
                    cust7 = new
                    {
                        value = ""
                    }
                }
            };

            JsonSerializerSettings settings = new JsonSerializerSettings();
            settings.NullValueHandling = NullValueHandling.Ignore;
            var myJson = JsonConvert.SerializeObject(tudhjs, settings);

Try this approach in your real circumstances:

var cust7 = new
{
   value = ""
};

if( string.IsNullOrWhiteSpace( cust7.value ) ) cust7 = null;

var tudhjs = new
{
   fields = new
   {
      sum = "st",
      // . . .
      cust = new
      {
         id = "23"
      },
      cust7
   }
};
