主要是添加Win32函数
其次是定义键盘按下，抬起的两个固定值。
[DllImport("User32.dll")] public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo); /// <summary> /// 按下 /// </summary> const int KEYEVENTF_KEYDOWN = 0; /// <summary> /// 抬起 /// </summary> const int KEYEVENTF_KEYUP = 0x2;
其次使用的时候是可以使用net自带的Keys的枚举值
比如说模拟发送：Ctrl+A Ctrl+C这两个按键的过程
keybd_event((byte)(Keys.LControlKey), 0, KEYEVENTF_KEYDOWN, 0);//按下ctrl keybd_event((byte)(Keys.A), 0, KEYEVENTF_KEYDOWN, 0);//按下A keybd_event((byte)Keys.A, 0, KEYEVENTF_KEYUP, 0);//抬起A keybd_event((byte)Keys.LControlKey, 0, KEYEVENTF_KEYUP, 0);//抬起ctrl keybd_event((byte)(Keys.LControlKey), 0, KEYEVENTF_KEYDOWN, 0); keybd_event((byte)(Keys.C), 0, KEYEVENTF_KEYDOWN, 0); keybd_event((byte)Keys.C, 0, KEYEVENTF_KEYUP, 0); keybd_event((byte)Keys.LControlKey, 0, KEYEVENTF_KEYUP, 0);
