Adding a URL Fragment to an MVC ActionLink

here is part of my code

this

<%= Html.ActionLink(Model[x].Title, "Index", "q", new { slug = Model[x].TitleSlug, id = Model[x].PostID }, null)%>

produces this url

http://localhost:61158/q/is_there_another_indiana_jones_movie_in_the_works/4

but I want to produce a url with a fragment, like this:

http://localhost:61158/q/is_there_another_indiana_jones_movie_in_the_works/4#1

Is there a way to do this using the HTML.ActionLink function?
