範例

下列範例示範衍生自的自訂伺服器控制項Control類別。The following example demonstrates a custom server control that derives from the Control class. InnerContent類別會覆寫Control.Render方法,會檢查類別是否有任何子控制項,在頁面上,並判斷控制項的第一個子系是否為常值的控制項。The InnerContent class overrides the Control.Render method, checks to see if the class has any child controls on the page and determines whether the first child of the control is a literal control. 如果這些條件都符合,覆寫的方法將寫入的 HTML 字串<H2 > 您的訊息:,常值控制項和一個結束的內容</H2 > 加入 Web Form 網頁的標記。If both of these conditions are met, the overridden method writes the HTML string <H2>Your Message:, the contents of the literal control, and a closing </H2> tag to the Web Forms page.

重要

這個範例有一個可接受使用者輸入的文字方塊,這可能會造成安全性威脅。This example has a text box that accepts user input, which is a potential security threat. 根據預設,ASP.NET Web 網頁會驗證使用者輸入未包含指令碼或 HTML 項目。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 如需詳細資訊,請參閱 Script Exploits Overview (指令碼攻擊概觀)。For more information, see Script Exploits Overview.

備註

這是當您開發自訂 ASP.NET 伺服器控制項衍生自的主要類別。This is the primary class that you derive from when you develop custom ASP.NET server controls. Control 沒有任何使用者介面 (UI) 的特定功能。Control does not have any user interface (UI) specific features. 如果您要撰寫的控制項,並沒有 UI,或結合其他控制項,會呈現其自己的 UI,衍生自ControlIf you are authoring a control that does not have a UI, or combines other controls that render their own UI, derive from Control. 如果您要撰寫沒有 UI 的控制項,則衍生自WebControl或任何控制在System.Web.UI.WebControls命名空間,提供適當的啟動點,以取得您的自訂控制項。If you are authoring a control that does have a UI, derive from WebControl or any control in the System.Web.UI.WebControls namespace that provides an appropriate starting point for your custom control.

Control類別是所有的 ASP.NET 伺服器控制項,包括自訂控制項、 使用者控制項和網頁的基底類別。The Control class is the base class for all ASP.NET server controls, including custom controls, user controls, and pages. ASP.NET 網頁是的執行個體Page類別,繼承自Control類別,處理要求的.aspx 副檔名的檔案。ASP.NET pages are instances of the Page class, which inherits from the Control class, and that handle requests for files that have an .aspx extension.

Control類別可以直接或間接作為使用者介面的一部分之您的 Web 應用程式,因此應該檢查來撰寫安全程式碼和保護應用程式會接著請確定最佳作法。The Control class can directly or indirectly be used as part of the user interface for your Web application, and as such should be scrutinized to make sure best practices for writing secure code and securing applications are followed.

如需這些主題的一般資訊,請參閱概觀的 Web 應用程式的安全性威脅NIB:安全性原則的最佳作法,並重要的安全性概念For general information on these topics, see Overview of Web Application Security Threats, NIB: Security Policy Best Practices, and Key Security Concepts. 如需特定資訊,請參閱 < 保護標準控制項How to:顯示安全的錯誤訊息How to:防止 Web 應用程式中的指令碼攻擊,藉由套用 HTML 編碼字串,並驗證控制項簡介For more specific information, see Securing Standard Controls, How to: Display Safe Error Messages, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Introduction to the Validation Controls.
