如何将 Ctrl+,（control 加逗号）指定为 WPF 菜单项的键盘快捷键？

Question

I would like to assign the keyboard shortcut Ctrl + , (control plus comma) to the "Preferences..." menu item. How do I do that?

有一个Key.OemComma in the Key http://msdn.microsoft.com/en-us/library/system.windows.input.key.aspx枚举。我用过Key.OemComma如下面的代码示例所示。从功能上来说，这工作得很好。但 GUI 方面：菜单项显示为

• 首选项（Ctrl+OemComma）

代替

• 首选项（Ctrl+,）

示例代码

InputGestureCollection keyInputs = new InputGestureCollection();
keyInputs.Add(new KeyGesture(Key.OemComma, ModifierKeys.Control));
preferencesCommand = new RoutedUICommand("Preferences...", "Preferences", typeof(MyCommands), keyInputs);

我觉得按键手势构造函数 http://msdn.microsoft.com/en-us/library/aa345788.aspx需要一个显示字符串就可以了。你可以这样称呼它：

InputGestureCollection keyInputs = new InputGestureCollection();
keyInputs.Add(new KeyGesture(Key.OemComma, ModifierKeys.Control, "Ctrl+,"));
preferencesCommand = new RoutedUICommand("Preferences...", "Preferences", typeof(MyCommands), keyInputs);
