Question

Hi I have my mvc app and this code snippet:

    protected override void OnException(ExceptionContext filterContext)
    {
        base.OnException(filterContext);
        ActionInvoker.InvokeAction(filterContext, "ErrorMessage");
    }

    public ActionResult ErrorMessage(ExceptionContext filterContext)
    {
        ViewModel<Exception> viewModel = ViewModelFactory.CreateFor(filterContext.Exception);
        return View(viewModel);
    }

The problem is that I can’t pass arguments to method. I thought it would be this filterContext but in ErrorMessage method it has all default values.

So my question is – How to pass some values to method that I invoke?

I don’t know if it was clear from my question but what I wanted achive was that I didn’t wanted to catch any exception in my controllers actions and still get good-looking message about error. So my solution which satisfies me is:

protected override void OnException(ExceptionContext filterContext)
    {
        base.OnException(filterContext);
        TempData.Add(MyCommons.Exception, filterContext.Exception);
        var controllerName = filterContext.RequestContext.RouteData.Values["Controller"];
        filterContext.Result =
            new RedirectToRouteResult(new RouteValueDictionary(new {controller = controllerName, action = "Error"}));
        filterContext.ExceptionHandled = true;
        filterContext.HttpContext.Response.Clear();

    }
