在我正在處理的項(xiàng)目中，我發(fā)現(xiàn)在每個(gè)操作的開(kāi)始和結(jié)束時(shí)，我都有相同的代碼來(lái)檢索，然后將對(duì)象存儲(chǔ)在 TempData[] 中。所有操作之間的代碼都是一致的，所以我想知道創(chuàng)建一個(gè)基本控制器類來(lái)執(zhí)行冗余重構(gòu)并將對(duì)象存儲(chǔ)在 TempData[] 中是否合理？有沒(méi)有更聰明的方法？我目前的代碼：public ActionResult Index(StepOne data){ var customer = TempData["customer"] as Customer; //do stuff with customer TempData["customer"] =customer; return View();}

為什么不創(chuàng)建一個(gè)名為 BaseController 或其他控制器的控制器，然后像下面編寫的代碼一樣從這個(gè) BaseController 繼承其他控制器。
//Your base controller
public class BaseController : Controller
{
//This will be executed after every action call on the controllers inherited from this BaseController.
//You can use OnActionExecuting in case you want the execution before the actions execution in your other controllers.
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
Controller controller = filterContext.Controller as Controller;
if (controller != null)
{
var customer = controller.TempData["customer"] as Customer;
//do stuff with customer
controller.TempData["customer"] = customer;
}
}
}
//Then your other controller
public class HomeController : BaseController
{
public ActionResult Index(StepOne data)
{
//You can get your TempData here too.
var customer = TempData["customer"] as Customer;
return View();
}
}
如果它不起作用或者您需要將此代碼更改為某種其他類型的行為，請(qǐng)告訴我。
