ServiceStack support for conditionally omitting fields from a REST response on a per-call basis

Question

At a minimum, I\'m looking for a way to conditionally exclude certain properties on the resource from being included in the r

Usually you can control the serialization of your DTOs by setting the DataMember attributes. With those attributes you can control if the property should have defaults or not. Meaning if you simply do not define the property of the object you want to return, it should not be serialized and therefore will not be shown in the resulting Json.

ServiceStack internally uses the standard DataContract...Serializer, so this should be supported

Otherwise you could also make use of dynamic objects and simply compose your object at runtime, serialize it and send it back. Here is a very very basic example:

        var seri = JsonSerializer.Create(new JsonSerializerSettings() { });

        using (var textWriter = new StringWriter())
        {
            var writer = new JsonTextWriter(textWriter);

            dynamic item = new { Id = id };

            seri.Serialize(writer, item);

            return textWriter.ToString();
        }
