passing action method parameter to ActionFilterAttribute in asp.net mvc
45,872
Building on the answer from @Pankaj and comments from @csetzkorn:
You pass the name of the parameter as a string then check the filterContext
public class NewAuthoriseAttribute : ActionFilterAttribute
{
public string IdParamName { get; set; }
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (filterContext.ActionParameters.ContainsKey(IdParamName))
{
var id = filterContext.ActionParameters[IdParamName] as Int32?;
}
}
}
[NewAuthorizeAttribute(IdParamName = "fooId")]
public ActionResult Index(int fooId)
{ ... }

I know that I can use the filterContext to get to it. However, this is not very flexible if the action method parameter is named differently. This should work:
[HttpGet] [NewAuthoriseAttribute(SomeId = id)] public ActionResult Index(int id) { ... public class NewActionFilterAttribute : ActionFilterAttribute { public int SomeId { get; set; } ...
but it does not (it does not even compile). Any ideas?
