Question

I have an enum:

public enum Navigation
{
    Top = 0,
    Left = 2,
    Footer = 3
}

And i have a controller action:

public ActionResult Quotes()
{
    return View();
}

I would like to be able to decorate my action as follow:

[Navigation.Top]
public ActionResult Quotes()
{
    return View();
}

Any idea how this could be accomplished, i will probably have to create a custom attribute, but how do i incorporate this enum into it?

Answer 1

One approach:

public static class Navigation{
  public class Top:ActionFilter /*any attribute*/{
   //magic
  }
  public class Left:ActionFilter{
   //magic
  }
}

[Navigation.Top]
public ActionResult Whatever(){}

If You do want to use enums, I’m afraid You won’t be able to use them as attributes. But You can pass it to attribute as an argument. Something like this:

public class NavigationAttribute:Attribute{
  public Navigation Place {get;set;}
}

[Navigation(Place=Navigation.Top)]
public ActionResult Whatever(){}
