Substitution 類別

定義

在輸出快取 Web 網頁上,指定不受限於快取的區段。Specifies a section on an output-cached Web page that is exempt from caching. 在此位置上,會擷取動態內容並用來替代 Substitution 控制項。At this location, dynamic content is retrieved and substituted for the Substitution control.

public ref class Substitution : System::Web::UI::Control
public class Substitution : System.Web.UI.Control
type Substitution = class
    inherit Control
Public Class Substitution
Inherits Control

Substitution

範例

下列程式碼範例示範如何以宣告方式Substitution將控制項加入至輸出快取網頁。The following code example demonstrates how to add a Substitution control declaratively to an output-cached Web page. 當頁面載入時, 系統會在標籤中向使用者顯示目前的日期和時間。When the page loads, the current date and time are displayed to the user in a label. 頁面的這個區段只會快取, 而且只會每隔60秒更新一次。This section of the page is cached and updated only every 60 seconds. 當控制項執行時, 它會GetCurrentDateTime呼叫方法。 SubstitutionWhen the Substitution control executes, it calls the GetCurrentDateTime method. 傳回的字串GetCurrentDateTime會向使用者顯示。The string returned by GetCurrentDateTime is displayed to the user. 頁面的這個區段不會進行快取, 而且會在每次重新整理頁面時更新。This section of the page is not cached and is updated each time the page is refreshed.

簡介Introduction

Substitution使用控制項來指定輸出快取網頁上的區段, 您可以在此頁面上, 將動態內容取代為控制項。Use the Substitution control to specify a section on an output-cached Web page where you want dynamic content substituted for the control. Substitution控制項為快取大部分內容的頁面提供簡化的部分頁面快取解決方案。The Substitution control offers a simplified solution to partial page caching for pages where the majority of the content is cached. 您可以輸出快取整個頁面, 然後使用Substitution控制項來指定不受快取的頁面部分。You can output-cache the entire page, and then use Substitution controls to specify the parts of the page that are exempt from caching. 快取的區域只會執行一次, 而且會在快取專案到期或清除之前, 從快取中重新執行。Cached regions execute only once and are replayed from the cache until the cache entry expires or is purged. 每次要求頁面時, 動態區域都會執行。Dynamic regions execute each time the page is requested. 此快取模型會簡化主要為靜態之頁面的程式碼, 因為您不需要在 Web 使用者控制項中封裝要快取的區段。This caching model simplifies the code for pages that are primarily static, because you do not have to encapsulate the sections to cache in Web user controls. 例如, 當您有一個頁面包含靜態內容 (例如新聞報導), 以及AdRotator顯示廣告的控制項時, 這個快取模型就很有用。For example, this caching model is useful in a scenario where you have a page that contains static content, such as news stories, and an AdRotator control that displays advertisements. 新聞報導不會變更, 這表示可以快取。The news stories do not change, which means that they can be cached. 不過, 每次使用者要求頁面時, 您都想要顯示新的公告。However, each time a user requests the page, you want to display a new advertisement. AdRotator控制項會直接支援快取後的替代, 並在每次頁面回傳時轉譯新的公告, 不論頁面是否已快取。The AdRotator control directly supports post-cache substitution and renders a new advertisement each time the page posts back, regardless of whether the page is cached.

注意

您可以將Substitution控制項放在快取頁面所包含的使用者控制項中。You can place a Substitution control in a user control that is contained in a cached page. 不過, 您無法將Substitution控制項放在輸出快取的使用者控制項中。However, you cannot place a Substitution control in an output-cached user control.

Substitution當控制項執行時, 它會呼叫傳回字串的方法。When the Substitution control executes, it calls a method that returns a string. 方法所傳回的字串是要在Substitution控制項位置的頁面上顯示的內容。The string that the method returns is the content to display on the page at the location of the Substitution control. 使用屬性, 即可指定Substitution控制項執行時要叫用的回呼方法名稱。 MethodNameUse the MethodName property to specify the name of the callback method to invoke when the Substitution control executes. 您指定的回呼方法必須是頁面上的靜態方法, 或是包含Substitution控制項的使用者控制項。The callback method that you specify must be a static method on the page or user control that contains the Substitution control. 回呼方法的簽章必須符合HttpResponseSubstitutionCallback HttpContext接受參數之委派的簽章, 並傳回字串。The signature for the callback method must match the signature for an HttpResponseSubstitutionCallback delegate that takes an HttpContext parameter and returns a string.

若要動作頁面的輸出快取, 您可以使用@ OutputCache指示詞、 HttpCachePolicy Cache類別或屬性。To manipulate the output cache for a page, you can use the @ OutputCache directive, the HttpCachePolicy class, or the Cache property. 如需快取頁面的詳細資訊, 請參閱快取ASP.NET 網頁和快取ASP.NET 網頁的部分For more information on caching pages, see Caching ASP.NET Pages and Caching Portions of an ASP.NET Page.

除了使用Substitution控制項以外, 您也可以HttpResponseSubstitutionCallback使用委派來取得替代快取行為。As an alternative to using the Substitution control, you can also get substitution caching behavior using a HttpResponseSubstitutionCallback delegate. 此外, 您可以在直接支援這項功能的控制項 (例如AdRotator控制項) 上取得替代快取行為。In addition, you can get substitution caching behavior on controls, such as the AdRotator control, that directly support this feature. 如需詳細資訊, 請參閱動態更新部分的快取頁面。For more information, see Dynamically Updating Portions of a Cached Page.
