很多小伙伴說，在Menu中，實現單個快捷鍵操作很簡單，怎么實現多個快捷鍵操作和，組合快捷鍵呢，今天他來了。

上代碼和效果圖

一、Ctrl + Shift + 任意子母鍵實現快捷鍵組合

<Window x:Class="XH.TemplateLesson.MenuWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:XH.TemplateLesson"mc:Ignorable="d"Title="MenuWindow" Height="450" Width="800"><Window.InputBindings><!-- 定義組合快捷鍵 Ctrl+Shift+S --><!--先要什么組合修改key 或者 Modifiers 即可注意：這里只可以改為Ctrl Alt Shift Windows + 任意字母鍵的快捷方式--><KeyBinding Key="S" Modifiers="Control+Shift" Command="{Binding NewCommand}" /></Window.InputBindings><Grid><Menu><MenuItem Header="新建(_F)"><MenuItem Header="新建" /><MenuItem Header="全部保存" Command="{Binding NewCommand}" InputGestureText="Ctrl+Shift+S"  /></MenuItem><MenuItem Header="編輯(_E)"/></Menu></Grid>
</Window>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;namespace XH.TemplateLesson
{/// <summary>/// MenuWindow.xaml 的交互邏輯/// </summary>public partial class MenuWindow : Window{public ICommand NewCommand { get; set; }public MenuWindow(){InitializeComponent();DataContext = this;NewCommand = new RelayCommand(ExecuteNew);}private void ExecuteNew(object parameter){MessageBox.Show("New Command Executed");}public class RelayCommand : ICommand{private readonly Action<object> _execute;private readonly Func<object, bool> _canExecute;public RelayCommand(Action<object> execute, Func<object, bool> canExecute = null){_execute = execute;_canExecute = canExecute;}public bool CanExecute(object parameter){return _canExecute == null || _canExecute(parameter);}public void Execute(object parameter){_execute(parameter);}public event EventHandler CanExecuteChanged{add { CommandManager.RequerySuggested += value; }remove { CommandManager.RequerySuggested -= value; }}}}
}

直接Ctrl + Shift + S彈出：

二、實現Ctrl + 多個字母鍵組合

<Window x:Class="XH.TemplateLesson.MenuWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:XH.TemplateLesson"mc:Ignorable="d" <!--綁定鍵盤事件-->PreviewKeyDown="Window_PreviewKeyDown"PreviewKeyUp="Window_PreviewKeyUp"Title="MenuWindow" Height="450" Width="800"><Grid><Menu><MenuItem Header="新建(_F)"><MenuItem Header="新建" /><MenuItem Header="整理代碼格式" InputGestureText="Ctrl+K+D"  /></MenuItem></Menu></Grid>
</Window>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;namespace XH.TemplateLesson
{/// <summary>/// MenuWindow.xaml 的交互邏輯/// </summary>public partial class MenuWindow : Window{private bool _isCtrlPressed;private bool _isAPressed;public MenuWindow(){InitializeComponent();}// 下方的K 和D 根據自己寫的代碼來進行修改private void Window_PreviewKeyDown(object sender, KeyEventArgs e){// 先 Cttrlif (e.Key == Key.LeftCtrl || e.Key == Key.RightCtrl){_isCtrlPressed = true;}// 再 Ctrl + K else if (e.Key == Key.K && _isCtrlPressed){_isAPressed = true;}// 最后 Cttrl + K + Delse if (e.Key == Key.D && _isCtrlPressed && _isAPressed){ExecuteCustomCommand();}}// 鍵盤釋放 如果釋放 無效private void Window_PreviewKeyUp(object sender, KeyEventArgs e){if (e.Key == Key.LeftCtrl || e.Key == Key.RightCtrl){_isCtrlPressed = false;}else if (e.Key == Key.K){_isAPressed = false;}}private void ExecuteCustomCommand(){MessageBox.Show("快捷鍵調用成功: Ctrl + K + D");}}
}

按下Ctrl + K + D:

單鍵 Alt + 字母彈出

<Menu><!--直接下劃線 + 字母 就可以alt + 字母彈出--><MenuItem Header="新建(_F)"><MenuItem Header="新建" /><MenuItem Header="整理代碼格式" InputGestureText="Ctrl+K+D"  /></MenuItem>
</Menu>

演示 ：

好了，以上就是WPF中Menu控件中，所有快捷鍵的使用方法了，感覺有用的話，點個贊唄。
