Windows提供了一个模拟键盘API函数Keybd_event(),该函数能触发一个按键事件,也就是说会产生一个WM_KEYDOWN或WM_KEYUP消息。
[DllImport("user32.dll", EntryPoint = "keybd_event")]
public static extern void keybd_event(
byte bVk, //虚拟键值
byte bScan,// 一般为0
int dwFlags, //这里是整数类型 0 为按下,2为释放
int dwExtraInfo //这里是整数类型 一般情况下设成为 0
);
使用方法:
keybd_event((byte)Keys.LWin, 0, 0, 0); //按下LWIN
keybd_event((byte)Keys.D, 0, 0, 0); //按下D
keybd_event((byte)Keys.LWin, 0, 2, 0); //释放LWIN
keybd_event((byte)Keys.D, 0, 2, 0); //释放D
补充:
1.调用API函数记得引用:using System.Runtime.InteropServices;
2.表格如下,是转过来的。
PS:如果上面(byte)keys.Alt等出现overflow 的问题,可以直接用表格的数字来代替。
