MVC C# ActionLink with multiple “news”

Question

How do I correct this so that the ActionLink reverts to http://localsite/forum/index/4 (where 4 is defined by the parent_id as shown below):

 @Html.ActionLink("Cancel", "Index", "Forum", new { @class = "btn"}, new{ @id=ViewBag.parent_id })

Currently it reverts to:

http://localhost:53731/Forum?class=btn

Thanks for your help,

Mark

Answer 1

Just invert the two last parameters :

@Html.ActionLink("Cancel", "Index", "Forum",  new{ @id=ViewBag.parent_id }, new { @class = "btn"})

routeValues should come before htmlAttributes

see msdn

Answer 2

看来您已经颠倒了论点。

 @Html.ActionLink("Cancel", "Index", "Forum", new{@id=ViewBag.parent_id }, new { @class = "btn"})
