HTML ActionLink method

Question

Let s say I have a class  public class ItemController Controller       public ActionResult Login int id                return View  Hi   id             On a page that is not located at the Item folder  where ItemController resides  I want to create a link to the Login method  So which Html ActionLink method I should use and what parameters should I pass   Specifically  I am looking for the replacement of the method   Html ActionLink article Title      new   controller    Articles   action    Details             id   article ArticleID      that has been retired in the recent ASP NET MVC incarnation

I wanted to add to Joseph Kingry s answer  He provided the solution but at first I couldn t get it to work either and got a result just like Adhip Gupta   And then I realized that the route has to exist in the first place and the parameters need to match the route exactly    So I had an id and then a text parameter for my route which also needed to be included too   Html ActionLink article Title   Login    Item   new   id   article ArticleID  title   article Title    null

You might want to look at the RouteLink   method That one lets you specify everything  except the link text and route name  via a dictionary

I wanted to add to Joseph Kingry s answer  He provided the solution but at first I couldn t get it to work either and got a result just like Adhip Gupta   And then I realized that the route has to exist in the first place and the parameters need to match the route exactly    So I had an id and then a text parameter for my route which also needed to be included too   Html ActionLink article Title   Login    Item   new   id   article ArticleID  title   article Title    null
