範例

下列範例會CommandBinding建立 ，將 和 CanExecuteRoutedEventArgs 處理程式對應ExecutedRoutedEventHandler至 Open 命令。

<Window.CommandBindings>
  <CommandBinding Command="ApplicationCommands.Open"
                  Executed="OpenCmdExecuted"
                  CanExecute="OpenCmdCanExecute"/>
</Window.CommandBindings>

// Creating CommandBinding and attaching an Executed and CanExecute handler
CommandBinding OpenCmdBinding = new CommandBinding(
    ApplicationCommands.Open,
    OpenCmdExecuted,
    OpenCmdCanExecute);

this.CommandBindings.Add(OpenCmdBinding);

' Creating CommandBinding and attaching an Executed and CanExecute handler
Dim OpenCmdBinding As New CommandBinding(ApplicationCommands.Open, AddressOf OpenCmdExecuted, AddressOf OpenCmdCanExecute)

Me.CommandBindings.Add(OpenCmdBinding)

以下顯示設定為 true的 CanExecuteRoutedEventHandlerCanExecute 。

void OpenCmdCanExecute(object sender, CanExecuteRoutedEventArgs e)
{
    e.CanExecute = true;
}

Private Sub OpenCmdCanExecute(ByVal sender As Object, ByVal e As CanExecuteRoutedEventArgs)
    e.CanExecute = True
End Sub

下列顯示執行 ExecutedRoutedEventHandler 命令時所建立 MessageBox 的 。

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
