是否同时按下Windows徽标键+ Powershell中的Alt + PrtScn？

Question

我通过引用该链接尝试了下面的代码，但一次无法按下这些键。

我需要任何更改吗？

$code = @'
namespace SendTheKeys {
  class SendIt {
   public static void Main(string[] args) {
    [System.Runtime.InteropServices.DllImport("user32.dll")]
        private static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

        private const int KEYEVENTF_EXTENDEDKEY = 1;
        private const int KEYEVENTF_KEYUP = 2;

        public static void KeyDown(Keys vKey)
        {
            keybd_event((byte)vKey, 0, KEYEVENTF_EXTENDEDKEY, 0);
        }

        public static void KeyUp(Keys vKey)
        {
            keybd_event((byte)vKey, 0, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
        }
  }
 }
}
