C#的系统钩子要点

1.载入钩子函数

  [DllImport("user32.dll", CharSet = CharSet.Auto,
            CallingConvention = CallingConvention.StdCall)]
        private static extern int CallNextHookEx(
            int idHook,
            int nCode,
            int wParam,
            IntPtr lParam);

        [DllImport("user32.dll", CharSet = CharSet.Auto,
            CallingConvention = CallingConvention.StdCall, SetLastError = true)]
        private static extern int SetWindowsHookEx(
            int idHook,
            HookProc lpfn,
            IntPtr hInstance,
            int threadId);

        [DllImport("user32.dll", CharSet = CharSet.Auto,
            CallingConvention = CallingConvention.StdCall, SetLastError = true)]
        private static extern int UnhookWindowsHookEx(int idHook);

//f上面三个分别是SetWindowsHookEx()建立钩子

//UnhookWindowsHookEx（）撤销钩子

//CallNextHookEx()回叫函数

呵呵

2。全局实现

SetWindowsHookEx(
                    WH_MOUSE_LL,
                    s_MouseDelegate,
                    Marshal.GetHINSTANCE(Assembly.GetExecutingAssembly().GetModules()[0]),//重点
                    0);

注意包含System.Reflection;

 

3.CallNextHookEx()就是自己的喜好了。嗯就这样
