asp.net的MVC的FormCollection [英] asp.net mvc formcollection

问题描述

public  ActionResult Edit(int  id, FormCollection formValues) {

    // Retrieve existing dinner
    Dinner dinner = dinnerRepository.GetDinner(id);

    // Update dinner with form posted values
    dinner.Title = Request.Form["Title"];
    dinner.Description = Request.Form["Description"];
    dinner.EventDate = DateTime.Parse(Request.Form["EventDate"]);
    dinner.Address = Request.Form["Address"];
    dinner.Country = Request.Form["Country"];
    dinner.ContactPhone = Request.Form["ContactPhone"];

    // Persist changes back to database
    dinnerRepository.Save();

    // Perform HTTP redirect to details page for the saved Dinner
    return RedirectToAction("Details", new { id = dinner.DinnerID });
}

formValues​​ 未在方法中使用。其目的是什么？

formValues is not used in the method. What is its purpose?
