A simple task in MVC, sometimes becomes a hard challenge.
Well,i have an Area called Admin. I've a page named "Forbidden" inside the Shared's directory in this area.
The goal is simple: I need to create an Html.ActionLink that generates a link to return to Home page which is OUTSIDE the Admin area.
So i try,<%= Html.ActionLink("Back","Index",new {controller="Home"})%>,and its generate :
http://localhost/Admin/Home/Index
Its wrong!I want:
http://localhost/Home/Index
How can i create a link from an area to the default controllers structure?
回答1:
Try this :
<%= Html.ActionLink("Back", "Index", "Home", new { area = "" }, null) %>
When using Areas, you should always specify the area your are calling in your ActionLinks by adding a route value as above, If the link is outside the area (as in your case), just use an empty parameter for the area.
There's a nice extension that i find essential in any ASP.NET MVC project (T4MVC). It makes your ActionLinks look much cleaner and it protects them against errors.
So the above code will look something like this :
<%= Html.ActionLink("Back", MVC.Home.Index()) %>
and when using an area :
<%= Html.ActionLink("Some Link", MVC.Admin.SomeController.SomeAction()) %>
It's a part of the MvcContrib project on codeplex here
You should consider using it.
