	使用方法

	

	 private RegisterHotKeyClass _RegisKey = new RegisterHotKeyClass();
	 private void Form2_Load(object sender, EventArgs e)
	 {
	 _RegisKey.Keys = Keys.Q;
	 _RegisKey.ModKey = RegisterHotKeyClass.MODKEY.MOD_CONTROL | RegisterHotKeyClass.MODKEY.MOD_ALT;
	 _RegisKey.WindowHandle = this.Handle;
	 _RegisKey.HotKey += new RegisterHotKeyClass.HotKeyPass(_Regis_HotKey);
	 _RegisKey.StarHotKey();
	
	 }

	 void _Regis_HotKey()
	 {
	 MessageBox.Show("ok");
	 }

	这里注册的是 CTRL+ALT+Q

	

	下面是全部的类

	

	using System;
	using System.Collections.Generic;
	using System.Text;
	using System.Runtime.InteropServices;
	using System.Windows.Forms;

	namespace Zgke.SysInfo
	{
	 /// <summary>
	 /// 系统热键注册
	 /// zgke@sina.com
	 /// qq 116149
	 /// </summary>
	 public class RegisterHotKeyClass
	 {
	 private IntPtr m_WindowHandle = IntPtr.Zero;
	 private MODKEY m_ModKey = MODKEY.MOD_CONTROL;
	 private Keys m_Keys = Keys.A;
	 private int m_WParam = 10000;
	 private bool Star = false;
	 private HotKeyWndProc m_HotKeyWnd = new HotKeyWndProc();

	 public IntPtr WindowHandle
	 {
	 get { return m_WindowHandle; }
	 set { if (Star)return; m_WindowHandle = value; }
	 }
	 public MODKEY ModKey
	 {
	 get { return m_ModKey; }
	 set { if (Star)return; m_ModKey = value; }
	 }
	 public Keys Keys
	 {
	 get { return m_Keys; }
	 set { if (Star)return; m_Keys = value; }
	 }
	 public int WParam
	 {
	 get { return m_WParam; }
	 set { if (Star)return; m_WParam = value; }
	 }

	 public void StarHotKey()
	 {
	 if (m_WindowHandle != IntPtr.Zero)
	 {
	 if (!RegisterHotKey(m_WindowHandle, m_WParam, m_ModKey, m_Keys))
	 {
	 throw new Exception("注册失败！");
	 }
	 try
	 {
	 m_HotKeyWnd.m_HotKeyPass = new HotKeyPass(KeyPass);
	 m_HotKeyWnd.m_WParam = m_WParam;
	 m_HotKeyWnd.AssignHandle(m_WindowHandle);
	 Star = true;
	 }
	 catch
	 {
	 StopHotKey();
	 }
	 }
	 }
	 private void KeyPass()
	 {
	 if (HotKey != null) HotKey();
	 }
	 public void StopHotKey()
	 {
	 if (Star)
	 {
	 if (!UnregisterHotKey(m_WindowHandle, m_WParam))
	 {
	 throw new Exception("卸载失败！");
	 }
	 Star = false;
	 m_HotKeyWnd.ReleaseHandle();
	 }
	 }

	
	 public delegate void HotKeyPass();
	 public event HotKeyPass HotKey;

	
	 private class HotKeyWndProc : NativeWindow
	 {
	 public int m_WParam = 10000;
	 public HotKeyPass m_HotKeyPass;
	 protected override void WndProc(ref Message m)
	 {
	 if (m.Msg == 0x0312 && m.WParam.ToInt32() == m_WParam)
	 {
	 if (m_HotKeyPass != null) m_HotKeyPass.Invoke();
	 }

	 base.WndProc(ref m);
	 }
	 }

	 public enum MODKEY
	 {
	 MOD_ALT = 0x0001,
	 MOD_CONTROL = 0x0002,
	 MOD_SHIFT = 0x0004,
	 MOD_WIN = 0x0008,
	 }

	 [DllImport("user32.dll")]
	 public static extern bool RegisterHotKey(IntPtr wnd, int id, MODKEY mode, Keys vk);

	 [DllImport("user32.dll")]
	 public static extern bool UnregisterHotKey(IntPtr wnd, int id);

	 }

	}
