注解

ComponentCommands类中的命令以及其他命令库类中的命令 ( ApplicationCommands如和NavigationCommands) 用于表示应用程序程序员经常遇到的一组常见命令。The commands in the ComponentCommands class and commands in the other command library classes, such as ApplicationCommands and NavigationCommands, are intended to represent a set of common commands that application programmers encounter frequently. 命令仅表示的实例RoutedCommand , 而不表示命令的实现逻辑。The commands only represent the instance of the RoutedCommand and not the implementation logic for the command. 实现逻辑通过CommandBindings绑定到命令。The implementation logic is bound to the command via a CommandBindings. 例如, 如果MoveLeft在控件 (命令目标) 上执行命令, 则命令目标可能不提供MoveLeft执行命令的逻辑, 因此, 应用程序编写器负责编写确定如何命令目标处理命令。For example, if the MoveLeft command is executed on a control (the command target), the logic that performs the MoveLeft command may not be provided by the command target, so the application writer is responsible for writing the logic that determines how the command target handles the command.

但许多控件确实为命令库中的许多命令提供实现逻辑。Many controls do provide implementation logic, though, for many of the commands in the command library. 例如TextBox , RedoPaste为命令Cut 、命令Copy 、命令、命令和命令提供逻辑。UndoFor example, the TextBox class provides logic for the Paste command, Cut command, Copy command, Undo command, and Redo command. 有关详细信息, 请参阅特定控件类的类文档。See the class documentation for particular control classes for more information.
