Get Image as stream or byte array using OpenRasta

Question

Would anyone be able to give me a quick pointer as to how I can get an OpenRasta handler that returns a byte array. To be exposed in the ResourceSpace without it being a JSON or XML object. i.e. I don't want it transcoded, I just want to be able to set the media type to "image/PNG" or similar.

Using ASP.Net MVC I can do it using a FileContentResult by returning

File(myByteArray, "image/PNG");

I just need to know the OpenRasta equivalent.

Thanks

You can just return a byte array as part of your handlerm but that will end up being served as application/octet-stream.

If you want to return files, you can simply return an implementation of IFile.

public class MyFileHandler {
  public IFile Get(int id) {
    var mybytes = new byte[];
    return new InMemoryFile(new MemoryStream(mybytes)) {
      ContentType = new MediaType("image/png");
    }
  }
}

You can also set the FileName property to return a specific filename, which will render a Content-Disposition header for you.
