Action Filter ActionParameters

I have an ActionFilterAttribute which I want to accept parameters through but I can't figure out pass them across.

So my action filter looks like this;

public class PreventAction : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        filterContext.Result = new RedirectResult("Home/Index");
    }
}

And I decorate my action like so;

[PreventAction]
public ActionResult Ideas()
{
  return View();
}

Now I want to add a parameter so I can call the filter like this;

[PreventAction(myParam1 = "1", myParam2 = "2")]
public ActionResult Ideas()
{
  return View();
}

Anyone know how to do this?

Just add MyParam1 and MyParam2 as properties of your PreventAction class. If you require the parameters to be there (rather then being optional), add them as arguments to a constructor for PreventAction instead.

Here's a quick tutorial of a simple attribute class from MSDN.
