Newton.JSON Serialize number to Enum item

Question

We want to serialize an object to JSON with Newton.JSON, but this Object use an enum and is then converted in the underlying int (see 'Datatype' in JSON below). How can ve proceed to get the "enum string" representation?

{
    "Timestamp": 1538568112852,
    "Metrics": [{
        "Name": "bdSeq",
        "Timestamp": 1538568112852,
        "Datatype": 4,
        "IsNull": false,
        "LongValue": 0
    }],
    "Seq": 18446744073709551615
}

You can substitute standard JsonSerializer with your own.

In startup.cs:

services.AddScoped(typeof(JsonSerializer), typeof(EnumAsStringSerializer));

And the class itself:

 public class EnumAsStringSerializer : JsonSerializer
    {
        public EnumAsStringSerializer()
        {
            this.ContractResolver = new CamelCasePropertyNamesContractResolver();
            this.Converters.Add(new StringEnumConverter
            {
                CamelCaseText = true,
            });
        }
    }
