Is there any order or pattern that action parameters in an MVC controller follow.
For example:
[HttpPost]
public ActionResult AddFiles(HttpPostedFileBase file, int catid, string description)
How does the controller know that this certain post parameter is for catid and so on.
The default model binder when trying to bind the
catidparameter looks for a value with that name. It looks in the form values, route data, query string and http file collection. Take a look at this.
