Downloading a File with C#

The below accompanies the previous example and is for downloading file with .Net C#. The file in this case was saved as binary data in a SQL database. Short and simple.

C#

    [HttpGet]
    [Route("DownloadFile/{Id}", Name = "DownloadFile")]
    public FileResult DownloadFile(int Id)
    {
        //Call to db to retrieve the file data record including a
        //"Binary" field that contains the bytes of the actual file
        var att = _data.RetrievFile(Id);

        return File(att.Binary, new MediaTypeHeaderValue(att.GetContentHeaderType(att.FileName)).ToString(), att.FileName);
    }
