Is there an enum for the ContentType property on a HttpWebResponse (“text/plain”, “application/octet-stream” etc.)?

Question

The closest thing I could find was System.Net.Mime.MediaTypeNames but that doesn\'t seem to have everything (like json) since it seems to be more focused around ema

Answer 1

IANA's database is most likely to be complete, but you would need to parse those pages to get a flat list.

There is also the mime.types file that comes with Apache which seems to have been derived from the said list.

Answer 2

An enum doesn't make much sense. MIME types are open-ended. That is, the list is not finite: new types are added from time to time.

See RFC4288: Media Type Specifications and Registration Procedures
