Я пытаюсь использовать API SendInput для автоматического повторного нажатия клавиши в игре. БЕЗ использования задержек. Я хочу, чтобы нажатия клавиш были как можно более быстрыми, поэтому я хотел бы воздержаться от использования задержек, таких как методы Task.Delay или Thread.Sleep.
Сосредоточьтесь на методе Strum.
Приведенный ниже код будет нажимать правую клавишу SHIFT 18 раз всякий раз, когда пользователь использует горячую клавишу Ctrl + B.

using System.Runtime.InteropServices;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Guitar_Hero_Strumming
{
public partial class GHSForm : Form
{
public GHSForm()
{
InitializeComponent();
}
private static async void Strum()
{
for (var i = 0; i < 18; i++)
{
var nInputs = new[]
{
new INPUT
{
type = InputType.KEYBOARD,
U =
{
ki =
{
wScan = ScanCodeShort.RSHIFT
}
}
}
};
SendInput((uint)nInputs.Length, nInputs, INPUT.Size);
await Task.Delay(1);
nInputs = new[]
{
new INPUT
{
type = InputType.KEYBOARD,
U =

Как видите, метод Strum содержит 2 экземпляра метода Task.Delay. Приведенный выше код НЕ будет работать, если я удалю 2 экземпляра метода Task.Delay.
Почему ввод с клавиатуры не отправляется, если я убираю задержки?
Как отправить ввод с клавиатуры без использования задержек?
Любая помощь приветствуется!
