Return with different ResponseDTO according querystring parameter value in Servicestack?

I want to return different type of response according QueryString parameter value. Example

http://localhost:8080/myservice?Type=low --> return responseType1
http://localhost:8080/myservice?Type=high --> return responseType2

according Type value in URL, I want to different type of response in service.

It is highly discouraged to change the return type based on how you call the Service. Your clients bind to the response of your Service -- changing it indiscriminately based on some runtime heuristic will break them.

But if you must, ServiceStack Services doesn't enforce a strict response type and lets you return any object, e.g:

public object Any(Request request)
{
    return request.Type == "low"
       ? responseType1
       : responseType2;
}

It does mean the Request DTO can no longer have a consistent IReturn<Response> interface marker and you'll now force the clients to know which Response is returned and when, which they'll have to maintain themselves on the call-site, e.g:

var response = client.Get<ResponseType>(new Request { Type = "low" });

This also affects metadata services which can't rely on the Service to have a consistent Response Type.
