I need to execute a method for every 5 seconds. How to do it with the Timer concept?

I need to know whether the timer runs and hits the method for every 5 seconds. So I tried the below code.

int autoPollingTime = Convert.ToInt32(configparams["AutoPollQueues"]);
System.Timers.Timer timer = new System.Timers.Timer();
timer.Interval = autoPollingTime; // time in Milliseconds
if (autoPollingTime != 0)
{
timer.Start();
if (timer.Interval == autoPollingTime)
{
Check();
Console.WriteLine("Timer completed");
Thread.Sleep(5000);
}
else
{
return;
}
}

While debugging the code, I should have got the console message for every 5 seconds. But I am not getting it. I do not know what is the problem.

Kindly Help.

What I have tried:

Googled but not getting the exact fix for the issue

// you can use TimerCallback

C#

Timer timer;
        public void CallFirstTime()
        {        
         
            TimerCallback tmCallback = your_method_name_to_call_for_every_5_second_like(interval_method);
            timer = new Timer(tmCallback, "any parameter", 0, 5000);
        }
 private void interval_method(object _SessionID)
        {
// this method call every 5 second
}

Don't use thread.Sleep - that prevents your UI thread from displaying anything.
And Interval doesn't change as the timer is running - it's the number of ticks between successive timer "activations".

What you need to do is handle the Timer.Elapsed event to find out when the timer has "fired":

void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
    {
    Console.WriteLine("Timer elapsed");
    }

private void MyButton_Click(object sender, EventArgs ew)
    {
    System.Timers.Timer timer = new System.Timers.Timer();
    timer.Interval = 5000;
    timer.Elapsed += timer_Elapsed;
    timer.Start();
    }

You will have to use Timer.Elapsed Event [^]
Timer Class (System.Timers)[^]
refer this example

using System;

namespace CPTemp
{
   public class Class1
    {
       static void Main(string[] args)
       {
           int autoPollingTime = 1000; //Convert.ToInt32(configparams["AutoPollQueues"]);
           System.Timers.Timer timer = new System.Timers.Timer();
           timer.Interval = autoPollingTime;  
           if (autoPollingTime != 0)
           {
               
               timer.Elapsed += timer_Elapsed;
               Console.WriteLine("Timer started...");
               timer.Start();
               Console.ForegroundColor = ConsoleColor.Red;
               Console.WriteLine("Press any key to stop the timer");
               
               Console.ReadKey();
               timer.Stop();
               Console.WriteLine("\n Timer Stopped");
               Console.ReadKey();
           }
       }

       static void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
       {
            Check(); 
       }

       private static void Check()
       {
           Console.ForegroundColor = ConsoleColor.White;
           Console.WriteLine("Timer running...");
       }
    }
}
