Question

Let’s say I currently have a Controller with the following Action:

    public ActionResult Index() {

        return View();
    }

I’d like to know if instead of this, I could have something like

    public ActionResult Index(MyModel model) {

        return View();
    }

where the model is in some way already filled up with data stored in the cookies.

Answer 1

Nope. It would have to be a [HttpPost] action.

[HttpPost]
public ActionResult Index(MyModel model)
{
 ...
 ...
 ...
}

As far as I know, [HttpGet], which is the default if you don’t specify an attribute, can only take simple value types.

public ActionResult Index(int id)
{
     MyModel model = dataLayer.getModel(id);
     return View(model);

}
