How to set custom headers when using IHttpActionResult?

Question

In ASP.NET Web API 2, the IHttpActionResult offers a lot of value in simplifying controller code and I\'m reluctant to stop using it, but I\'ve hit a problem.

Answer 1

You can create a HttpResponseMessage, add headers as needed and then create ResponseMessageResult from it:

HttpResponseMessage response =new HttpResponseMessage(HttpStatusCode.OK);
response.Headers.Add("MyHeader", "MyHeaderValue");
return ResponseMessage(response);
