Question

I have the following method

 public ActionResult Search(FormCollection form)
    {
         .......
        Publication[] publicationsResult = server.SearchLibrary(this.getSession(), sq);

        return RedirectToAction("BookListing", new { publications = publicationsResult });
    }

Which gets a list of publications from the server and stores it in an array of type Publication.

I would like to show the results in another page, thus I redirected to the following method:

public ActionResult BookListing(Publication[] publications)
    {
        Publication[] p = publications;
        return View(publications);
    }

And I also have the following Routes defined:

routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Library", action = "Search", id = UrlParameter.Optional } // Parameter defaults
        );

        routes.MapRoute(
            "PublicationListing", // Route name
            "{controller}/{action}/{publications}", // URL with parameters
            new { controller = "Library", action = "BookListing", publications = UrlParameter.Optional } // Parameter defaults
        );

When in Search the publications array is populated with over 13000 objects, however when I redirect to BookListing null is passed.

Is there a way to pass an array of objects from one action method to another using RedirectToAction?

Thanks.

You always have the TempData collection. This is persisted between the action redirects for a single request and so provides you with storage for anything like this…
