示例

以下示例创建一个在执行命令时打开MessageBox的命令ExecutedRoutedEventHandler。

void OpenCmdExecuted(object target, ExecutedRoutedEventArgs e)
{
    String command, targetobj;
    command = ((RoutedCommand)e.Command).Name;
    targetobj = ((FrameworkElement)target).Name;
    MessageBox.Show("The " + command +  " command has been invoked on target object " + targetobj);
}

Private Sub OpenCmdExecuted(ByVal sender As Object, ByVal e As ExecutedRoutedEventArgs)
    Dim command, targetobj As String
    command = CType(e.Command, RoutedCommand).Name
    targetobj = CType(sender, FrameworkElement).Name
    MessageBox.Show("The " + command + " command has been invoked on target object " + targetobj)
End Sub

注解

ExecutedRoutedEventHandler 表示实现命令 RoutedCommand逻辑的方法。 将实现逻辑与命令分离，允许从不同的源和类型调用该命令，并启用命令逻辑的集中化。

此事件数据类也用于 CommandManager.Executed 和 CommandManager.PreviewExecuted。 但大多数实际处理程序将处理 Executed 特定 CommandBinding事件，而不是在 CommandManager 级别工作。

有关命令的详细信息，请参阅 命令概述。
