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：
