对系统模拟按键方面的知识和按键映射代码做了一下梳理,在这里分享出来,适用于开发自动操作工具和游戏外挂。

主代码:

public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key click flag
        public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
        [DllImport("user32.dll")]
        private static extern void keybd_event(byte bVk, byte bSCan, int dwFlags, int dwExtraInfo);
        [DllImport("user32.dll")]
        private static extern byte MapVirtualKey(byte wCode, int wMap);

        public static void 模拟按下按键(VirtualKeyCode 虚拟按键代码)
        {
            var code = (byte)虚拟按键代码;
            keybd_event(code, 0, 0, 0);
        }

        public static void 模拟弹起按键(VirtualKeyCode 虚拟按键代码)
        {
            var code = (byte) 虚拟按键代码;
            keybd_event(code, 0, KEYEVENTF_KEYUP, 0);
        }

        public static void 模拟单击按键(VirtualKeyCode 虚拟按键代码)
        {
            var code = (byte)虚拟按键代码;
            keybd_event(code, 0, KEYEVENTF_EXTENDEDKEY, 0);
        }

网上关于keybd_event的dwFlags参数功能说法很混乱,经我测试貌似是KEYEVENTF_EXTENDEDKEY表示一次单击,0表示按下,KEYEVENTF_KEYUP表示弹起,不一定完全正确,希望高人指点一下。

另外MapVirtualKey的作用实在不懂,所以就没用上,看到有人这么调用不知有什么区别:

var code = (byte)虚拟按键代码;
            keybd_event(code, MapVirtualKey(code,0), 0, 0);

我试过好像也没什么变化~到底MapVirtualKey是干什么用的呢??

VirtualKeyCode枚举:
