您需要尝试与此相似的内容

private void AddHotKeys()
{
        try
        {
            RoutedCommand firstSettings = new RoutedCommand();
            firstSettings.InputGestures.Add(new KeyGesture(Key.A, ModifierKeys.Alt));
            CommandBindings.Add(new CommandBinding(firstSettings , My_first_event_handler));

            RoutedCommand secondSettings = new RoutedCommand();
            secondSettings.InputGestures.Add(new KeyGesture(Key.B, ModifierKeys.Alt));
            CommandBindings.Add(new CommandBinding(secondSettings , My_second_event_handler));
        }
        catch (Exception err)
        {
            //handle exception error
        }
}

活动

private void My_first_event_handler(object sender, ExecutedRoutedEventArgs e) 
{
      //handler code goes here.
      MessageBox.Show("Alt+A key pressed");
}

private void My_second_event_handler(object sender, RoutedEventArgs e) 
{
     //handler code goes here. 
     MessageBox.Show("Alt+B key pressed");
}

如果您关注MVVM，可以试试这个reference

<UserControl.InputBindings>
<KeyBinding Modifiers="Control" 
            Key="E" 
            Command="{input:CommandBinding EditCommand}"/>

See the reference

Answer 2

您应该可以在xaml中执行此操作

<Window.InputBindings>
    <KeyBinding Command="{Binding MyCommand}" Key="F2"/>
</Window.InputBindings>

<Button Command="{Binding MyCommand}"/>

MyCommand是在您的窗口中实现的ICommand＆＃39; / view的viewmodel。

因此按钮和F2输入绑定都将执行相同的命令。
