備註

若要建立您自己的控制項類別,請從 UserControlControl 類別,或從其他 Windows Forms 提供的控制項繼承。To create your own control class, inherit from the UserControl, Control classes, or from the other Windows Forms provided controls. 如需撰寫自訂控制項的詳細資訊,請參閱使用 .NET Framework 開發自訂 Windows Forms 控制項For more information about authoring custom controls, see Developing Custom Windows Forms Controls with the .NET Framework.

Control 類別會執行將資訊顯示給使用者的類別所需的非常基本功能。The Control class implements very basic functionality required by classes that display information to the user. 它會透過鍵盤和指向裝置來處理使用者輸入。It handles user input through the keyboard and pointing devices. 它會處理訊息路由和安全性。It handles message routing and security. 它會定義控制項的界限(其位置和大小),但不會執行繪製。It defines the bounds of a control (its position and size), although it does not implement painting. 它會提供視窗控制碼(hWnd)。It provides a window handle (hWnd).

Windows Forms 控制項會使用環境屬性,因此子控制項的外觀可能會類似其周圍的環境。Windows Forms controls use ambient properties so child controls can appear like their surrounding environment. 環境屬性是控制項屬性,如果未設定,則會從父控制項抓取。An ambient property is a control property that, if not set, is retrieved from the parent control. 如果控制項沒有 Parent,而且未設定屬性,則控制項會嘗試透過 Site 屬性來判斷環境屬性的值。If the control does not have a Parent, and the property is not set, the control attempts to determine the value of the ambient property through the Site property. 如果控制項不是位置,如果網站不支援環境屬性,或如果未在 AmbientProperties 上設定屬性,控制項就會使用自己的預設值。If the control is not sited, if the site does not support ambient properties, or if the property is not set on the AmbientProperties, the control uses its own default values. 通常,環境屬性代表控制項的特性,例如 BackColor,會傳達給子控制項。Typically, an ambient property represents a characteristic of a control, such as BackColor, that is communicated to a child control. 例如,Button 預設會有相同的 BackColor 做為其父系 FormFor example, a Button will have the same BackColor as its parent Form by default. Control 類別所提供的環境屬性包括: CursorFontBackColorForeColorRightToLeftAmbient properties provided by the Control class include: Cursor, Font, BackColor, ForeColor, and RightToLeft.

注意

若要讓您的 Windows Forms 應用程式支援視覺化樣式,請務必將 FlatStyle 屬性設定為 System,並將資訊清單包含在可執行檔中。To make your Windows Forms application support visual styles, be sure to set the FlatStyle property to System and include a manifest with your executable. 資訊清單是一種 XML 檔案,包含在應用程式可執行檔中做為資源,或當做與執行檔位於相同目錄中的個別檔案。A manifest is an XML file that is included either as a resource within your application executable or as a separate file that resides in the same directory as the executable file. 如需資訊清單的範例,請參閱 FlatStyle 列舉的範例一節。For an example of a manifest, see the Example section of the FlatStyle enumeration. 如需使用視覺化樣式的詳細資訊,請參閱視覺化樣式For more information about using visual styles, see Visual Styles.

Windows Forms 具有內建的協助工具支援,並提供您應用程式的相關資訊,讓它能夠與協助工具用戶端應用程式搭配使用,例如螢幕放大鏡和瀏覽器公用程式、語音輸入公用程式、螢幕鍵盤、替代輸入裝置,以及鍵盤增強公用程式。Windows Forms has accessibility support built in, and provides information about your application that enables it to work with accessibility client applications such as screen enlarger and reviewer utilities, voice input utilities, on-screen keyboards, alternative input devices, and keyboard enhancement utilities. 有時候您會想要提供其他資訊給協助工具用戶端應用程式。Sometimes you will want to provide additional information to accessibility client applications. 有兩種方式可提供這項額外資訊。There are two ways of providing this additional information. 您可以設定 AccessibleNameAccessibleDescriptionAccessibleDefaultActionDescriptionAccessibleRole 屬性值,這將會報告給協助工具用戶端應用程式。You can set the AccessibleName, AccessibleDescription, AccessibleDefaultActionDescription, and AccessibleRole property values, which will be reported to accessibility client applications. 這個方法通常用來為現有的控制項提供有限的協助工具資訊。This method is typically used to provide limited accessibility information for existing controls. 或者,您也可以撰寫自己的類別,衍生自 AccessibleObjectControl.ControlAccessibleObject 類別,視需要提供多個協助工具資訊。Alternatively, you can write your own class deriving from the AccessibleObject or Control.ControlAccessibleObject classes, providing as much accessibility information as needed.

注意

若要維持較佳的效能,請不要在其「函式」中設定控制項的大小。To maintain better performance, do not set the size of a control in its constructor. 慣用的方法是覆寫 DefaultSize 屬性。The preferred method is to override the DefaultSize property.

注意

請勿在其函式中加入 Control 的資料系結。Do not add data bindings for a Control in its constructor. 這麼做會導致程式碼產生錯誤,而且可能會造成不必要的行為。Doing so will cause errors in code generation and can cause unwanted behavior.

System.Windows.Forms 命名空間中的大部分控制項都會使用基礎 Windows 通用控制項做為建立基礎的基底。The majority of the controls in the System.Windows.Forms namespace use the underlying Windows common control as a base to build on. 如需 Windows 通用控制項的詳細資訊,請參閱一般控制項參考For more information about the Windows common controls, see General Control Reference.

若要從不同的進程識別 Windows Forms 控制項,請使用標準 SendMessage 呼叫來傳遞 WM_GETCONTROLNAME 訊息。To identify Windows Forms controls from a separate process, use a standard SendMessage call to pass the WM_GETCONTROLNAME message. WM_GETCONTROLNAME 與語言和 Windows 階層無關。WM_GETCONTROLNAME is independent of the language and Windows hierarchy. 如需詳細資訊,請參閱自動化 Windows Forms的「Windows Forms 的建議解決方案」主題。For more information, see the "Recommended Solution for Windows Forms" topic inAutomating Windows Forms.

使用 [InvokeRequired] 屬性,從多個執行緒同步處理控制項的存取權限。Use the InvokeRequired property to synchronize access to the control from multiple threads. 如需多執行緒 Windows Forms 控制項的詳細資訊,請參閱 How 至:對 Windows Forms 控制項進行安全線程呼叫For more information about multithreaded Windows Forms controls, see How to: Make Thread-Safe Calls to Windows Forms Controls

執行緒安全性

只有下列成員是安全線程: BeginInvoke(Delegate)EndInvoke(IAsyncResult)Invoke(Delegate)InvokeRequired,以及 CreateGraphics() (如果已建立控制項的控制碼)。Only the following members are thread safe: BeginInvoke(Delegate), EndInvoke(IAsyncResult), Invoke(Delegate), InvokeRequired, and CreateGraphics() if the handle for the control has already been created. 在背景執行緒上建立控制項的控制碼之前呼叫 CreateGraphics(),可能會造成不合法的跨執行緒呼叫。Calling CreateGraphics() before the control's handle has been created on a background thread can cause illegal cross thread calls.
