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          


        

Answer 1

For exceptions, I usually do

 catch (Exception ex)
        {
            return InternalServerError(new ApplicationException("Something went wrong in this request. internal exception: " + ex.Message));
        }

Answer 2

Anyone who is interested in returning anything with any statuscode with returning ResponseMessage:

//CreateResponse(HttpStatusCode, T value)
return ResponseMessage(Request.CreateResponse(HttpStatusCode.XX, object));

Answer 3

Simple:

return ResponseMessage(Request.CreateErrorResponse(HttpStatusCode.InternalServerError, "Your message"));

Remember to reference System.Net.Http and System.Net.
