一：新建类HotKeys命名空间：
using System.Runtime.InteropServices;
二：注册热键API
[DllImport("user32")]
public static extern bool RegisterHotKey(IntPtr hWnd, Int32 id, UInt32 fsModifilters, Keys key);
[DllImport("user32")]
public static extern bool UnregisterHotKey(IntPtr hWnd, Int32 id);
三：注册/注销热键
public static void RegHotKey(IntPtr ptr)
{
RegisterHotKey(ptr, , , Keys.F5);
RegisterHotKey(ptr, , , Keys.F6);
}
public static void UnRegHotKey(IntPtr ptr)
{
UnregisterHotKey(ptr, );
UnregisterHotKey(ptr, );
}
四：Form窗体调用
HotKeys.RegHotKey(this.Handle); //Load或Active事件
HotKeys.UnRegHotKey(this.Handle);//Closing事件
五：Form窗体重写WndPro
protected override void WndProc(ref Message m)
{
const Int32 WM_HOTKEY = 0x0312;
IntPtr ptr = m.WParam;
String sptr = ptr.ToString();
switch (m.Msg)
{
case WM_HOTKEY:
if (sptr.Equals(""))
{
tsb_OK(); //调用事件
}
else if (sptr.Equals(""))
{
barbtn_Referral();
}
break;
}
base.WndProc(ref m);
}
