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

or

RelayCommand

.
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));

}

}
