You need to use KeyBindings (and CommandBindings if you (re)use RoutedCommands such as those found in the ApplicationCommands class) for that inthe controls where the shortcuts should work.

e.g.

<Window.CommandBindings>

        <CommandBinding Command="New" Executed="CommandBinding_Executed" />

</Window.CommandBindings>

<Window.InputBindings>

        <KeyBinding Key="N" Modifiers="Control" Command="New"/>

</Window.InputBindings>

 

 

For custom RoutedCommands:

static class CustomCommands

{

    public static RoutedCommand DoStuff = new RoutedCommand();

}

usage:

<Window

    ...

    xmlns:local="clr-namespace:MyNamespace">

        <Window.CommandBindings>

                <CommandBinding Command="local:CustomCommands.DoStuff" Executed="DoStuff_Executed" />

        </Window.CommandBindings>

        <Window.InputBindings>

                <KeyBinding Key="D" Modifiers="Control" Command="local:CustomCommands.DoStuff"/>

        </Window.InputBindings>

    ...

</Window>

(It is often more convenient to implement the ICommand interface rather than using RoutedCommands. You canhave a constructor which takes delegates for Execute and CanExecute to easily create commands which do different things, suchimplementations are often called DelegateCommand orRelayCommand. This wayyou do not need CommandBindings.)

 

MenuItem上显示快捷键：

<MenuItemHeader="{x:Static Prop:Resources.File_AddBookItemHeader}" InputGestureText="Ctrl+N"Command="local:CustomCommands.DoStuff" Foreground="Black"/>

也可以不用再xaml中声明keyBinding,而用代码：

    static classCustomCommands

    {

        public staticRoutedCommand DoStuff = new RoutedCommand();

        staticCustomCommands()

        {

           DoStuff.InputGestures.Add(new KeyGesture(Key.N, ModifierKeys.Control));

        }

    }
