c# - Return content with IHttpActionResult for non-OK response

Question

For returning from a Web API 2 controller, I can return content with the response if the response is OK (status 200) like this:

    public IHttpActionResult Get()
    {
        string myResult = ...
        return Ok(myResult);
    }

If possible, I want to use the built-in result types here when possible: https://msdn.microsoft.com/en-us/library/system.web.http.results(v=vs.118).aspx

My question is, for another type of response (not 200), how can I return a message (string) with it? For example, I can do this:

    public IHttpActionResult Get()
    {
       return InternalServerError();
    }

but not this:

    public IHttpActionResult Get()
    {
       return InternalServerError("Message describing the error here");
    }

Ideally I want this to be generalized so that I can send a message back with any of the implementations of IHttpActionResult.

Do I need to do this (and build my own response message):

    public IHttpActionResult Get()
    {
       HttpResponseMessage responseMessage = ...
       return ResponseMessage(responseMessage);
    }

or is there a better way?

You can use this:

return Content(HttpStatusCode.BadRequest, "Any object");
