ASP.NET MVC - passing parameters to the controller

Question

I have a controller with an action method as follows:

public class InventoryController : Controller
{
    public ActionResult ViewStockNext(int firstItem)
           


        

Answer 1

or do it with Route Attribute:

public class InventoryController : Controller
{
    [Route("whatever/{firstItem}")]
    public ActionResult ViewStockNext(int firstItem)
    {
        int yourNewVariable = firstItem;
        // ...
    }
}
