自定义winform 的keypass事件 求优化！
//添加自定义类

C# code

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Runtime.InteropServices;using System.Windows.Forms;namespace 编辑器{    public class HotKey: Form1    {        //委托 key 函数        public delegate void delegateKeyPress(object sender, EventArgsKey e);        // 自增ID 标示        private int idForDiff = 0;        public IntPtr hWnd{get;set;}  //当前空中句柄        public Control control { get; set; }        //要注册的按键：        public List<keyNode> keys { get; set; }        /// <summary>        /// 如果函数执行成功，返回值不为0。        /// 如果函数执行失败，返回值为0。要得到扩展错误信息，调用GetLastError。        ///         /// </summary>        /// <param name="hWnd"></param>        /// <param name="id"></param>        /// <param name="fsModifiers"></param>        /// <param name="vk"></param>        /// <returns></returns>        [DllImport("user32.dll ", SetLastError = true)]        public static extern bool RegisterHotKey(            IntPtr hWnd,                                 //要定义热键的窗口的句柄            int id,                                           //定义热键ID（不能与其它ID重复）                                  KeyModifiers fsModifiers,       //标识热键是否在按Alt、Ctrl、Shift、Windows等键时才会生效            Keys vk                                           //定义热键的内容            );        [DllImport("user32.dll ", SetLastError = true)]        public static extern bool UnregisterHotKey(            IntPtr hWnd,                                 //要取消热键的窗口的句柄            int id                                             //要取消热键的ID            );        //定义了辅助键的名称（将数字转变为字符以便于记忆，也可去除此枚举而直接使用数值）        [Flags()]        public enum KeyModifiers        {            None = 0,            Alt = 1,            Ctrl = 2,            Shift = 4,            WindowsKey = 8        }        //构造函数        public HotKey(IntPtr hwnd)        {            this.control = null;            this.hWnd = hwnd;            this.keys = new List<keyNode>();//对象init        }        //构造函数        public HotKey(Control control)        {            this.control = control;            this.hWnd = control.Handle;            this.keys = new List<keyNode>();//对象init        }        //注册按键：        public void AddKeyToRegister(IEnumerable<keyNode> keys)        {            foreach (keyNode key in keys)            {                keyNode k = new keyNode(key.key,key.keyMode,key.keyPassFunction);                HotKey.RegisterHotKey(this.hWnd, this.idForDiff, k.keyMode, k.key);                k.keyPassFunction = key.keyPassFunction;                k.id = this.idForDiff;                this.idForDiff++;                this.keys.Add(k);            }        }        public void AddKeyToRegister(Keys key,HotKey.KeyModifiers keyMode, delegateKeyPress keyFunction)        {            keyNode k = new keyNode(key, keyMode, keyFunction);            HotKey.RegisterHotKey(this.hWnd, this.idForDiff, k.keyMode, k.key);            k.id = this.idForDiff;            this.idForDiff++;            this.keys.Add(k);        }                        }    //每一个Key对象    public class keyNode    {        public Keys key { get; set; }        public 编辑器.HotKey.KeyModifiers keyMode { get; set; }        public int id { get; set; }        public 编辑器.HotKey.delegateKeyPress keyPassFunction { get; set; }        public keyNode(Keys key, 编辑器.HotKey.KeyModifiers keyModefier,编辑器.HotKey.delegateKeyPress keyPassFunction )        {            this.key = key;            this.keyMode = keyModefier;            this.keyPassFunction = keyPassFunction;        }    }    public class EventArgsKey : EventArgs    {        public Keys key { get; set; }        public int keyId { get; set; }        public EventArgsKey(Keys k,int id)        {            this.key = k;            this.keyId = id;        }    }} 
 

在winform 中应用：

C# code

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.IO;namespace 编辑器{        public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        public  HotKey keyManager;        private void Form1_Load(object sender, EventArgs e)        {            keyManager = new HotKey(this);            keyManager.AddKeyToRegister(Keys.X, HotKey.KeyModifiers.Ctrl, this.ctrlXPress);                }        //按键 事件        public void ctrlXPress(object sender, EventArgsKey e)        {            MessageBox.Show("ctrl+X");        }//下面这段代码少不了，我想提到 自定义类中，不让使用都看到，可是想来想去，想不出方法。//        /// <summary>        /// key Press 按键重写        /// </summary>        /// <param name="m">message</param>        protected override void WndProc(ref   Message m)        {            const int WM_HOTKEY = 0x0312;            //按快捷键              if (m.Msg == WM_HOTKEY)            {                foreach (keyNode key in keyManager.keys)                {                    if (key.id == m.WParam.ToInt32())                    {                        if (key.keyPassFunction != null)                        {                            key.keyPassFunction(((keyManager.control != null) ? keyManager.control : null), new EventArgsKey(key.key, key.id));                        }                    }                }            }            base.WndProc(ref   m);        }     }    }

[解决办法]
定义一个类，继承自 Form，WndProc放到这个类里，还是override，你的窗体继承自自定义类，并且 WndProc中，先base.WndProc(ref m);这样可以现在自定义类中做一些处理
