C＃模拟VolumeMute按
我得到以下代码来模拟volumemute按键：
[DllImport("coredll.dll", SetLastError = true)]
static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
byte VK_VOLUME_MUTE = 0xAD;
const int KEYEVENTF_KEYUP = 0x2;
const int KEYEVENTF_KEYDOWN = 0x0;
private void button1_Click(object sender, EventArgs e)
{
keybd_event(VK_VOLUME_MUTE, 0, KEYEVENTF_KEYDOWN, 0);
keybd_event(VK_VOLUME_MUTE, 0, KEYEVENTF_KEYUP, 0);
}
没有找到相关结果
