class Program
{
static async Task Main(string[] args)
{
string path = "C:/Example"; // yangi katalog manzili
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
await Task.Run(() => Directory.CreateDirectory(path));
stopwatch.Stop();
Console.WriteLine($"Katalog yaratish vaqti: {stopwatch.Elapsed}");
}
}
