推荐答案
使用命令，因为这些命令可以连接到快捷键.然后可以再次将命令绑定到按钮.在此处阅读有关此内容的信息: http://www.switchonthecode.com/tutorials/wpf-tutorial-command-bindings-and-custom-commands [ ^ ]或此处: http://msdn.microsoft.com/en-us/library/ms752308.aspx [ ^ ]
最好的问候，

Use commands as these can be connected to shortcut keys. The commands then again can be bound to the buttons. Read some about it here: http://www.switchonthecode.com/tutorials/wpf-tutorial-command-bindings-and-custom-commands[^] or here: http://msdn.microsoft.com/en-us/library/ms752308.aspx[^]

您是否尝试过将CTRL + S与菜单命令相关联，以使框架为您处理乏味.
Have you tried associating CTRL+S with the menu command, that way the framework deals with the tedium for you.
