You can use System.Timers.Timer or System.Threading.Timer to run a specific code block at a specific time without busy-waiting. Here's an example using System.Timers.Timer: using System; using System.Timers; class Program { private static Timer timer; static void Main(string[] args) { // Set the desired time to trigger the event (13:15) DateTime targetTime = DateTime.Today.AddHours(13).AddMinutes(15); // Calculate the time difference between now and the target time double interval = (targetTime - DateTime.Now).TotalMilliseconds; // If the target time has already passed today, schedule it for the next day if (interval

Timer class in C#. can perform this task: using System; using System.Threading; public class MyScheduler { private Timer timer; public MyScheduler() { // Set the target time for the action (e.g., 13:15) DateTime targetTime = DateTime.Today.AddHours(13).AddMinutes(15); // Calculate the time remaining until the target time int dueTime = (int)targetTime.Subtract(DateTime.Now).TotalMilliseconds; if (dueTime

You can achive this through timer class. Here is the code example: static void Main() { // Define the time you want the code to run every day int targetHour = 15; // 3:00 PM int targetMinute = 30; // 3:30 PM // Calculate the time difference from now to the target time TimeSpan timeUntilTarget = CalculateTimeUntilTarget(targetHour, targetMinute); // Schedule the code to run at the target time every day Timer timer = new Timer(ExecuteCode, null, timeUntilTarget, TimeSpan.FromDays(1)); // Keep the program running until manually terminated Console.WriteLine("Code scheduled to run every day at {0}:{1}", targetHour, targetMinute); Console.WriteLine("Press any key to exit..."); Console.ReadKey(); } static TimeSpan CalculateTimeUntilTarget(int targetHour, int targetMinute) { DateTime now = DateTime.Now; DateTime targetTime = new DateTime(now.Year, now.Month, now.Day, targetHour, targetMinute, 0); if (targetTime
