Custom JsonConverter for Dictionary<string. object>

[WenningQiu]

I am trying to write a JsonConverter for the interface type below:

    // interface
    [JsonConverter(typeof(IAmbientDataJsonConverter))]
    public interface IAmbientData : IDictionary<string, object>
    {
    }

    // Implementation class
    public class AmbientData : SafeSerializableDictionary<string, object>, IAmbientData, IEquatable<AmbientData>
    {
    }

I am running into an issue in Write() method - since the values in IAmbientData dictionary can be of arbitrary types, how do I properly invoke the Write() method on the retrieved converter object since Write() is not defined on the base JsonConverter class?

    public class IAmbientDataJsonConverter : JsonConverter<IAmbientData>
    {
        public override IAmbientData Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
        {
            var dict = JsonSerializer.Deserialize<Dictionary<string, object>>(ref reader, options);
            return new AmbientData(dict);
        }

        public override void Write(Utf8JsonWriter writer, IAmbientData ambientData, JsonSerializerOptions options)
        {
            writer.WriteStartObject();

            foreach (var (key, value) in ambientData)
            {
                writer.WritePropertyName(options.PropertyNamingPolicy?.ConvertName(key) ?? key);
                options.GetConverter(value.GetType()).Write(writer, value, options); // HOW TO MAKE WRITE() CALL HERE? 
            }

            writer.WriteEndObject();
        }
    }

Hmm, this code seems to work:

        public override void Write(Utf8JsonWriter writer, IAmbientData ambientData, JsonSerializerOptions options)
        {
            JsonSerializer.Serialize(writer, ambientData, typeof(IDictionary<string, object>), options);
        }
