How to stop execution when the time is reached?

Question

C++ / C#

Hello.
There is a loop in which certain code is executed, for example:

while(true)
{
  
  method1();
  
  method2();
  
  method3();
  
}

How to stop this loop after 3 minutes?

Answer 1

Use CancellationToken and CancellationTokenSource with the CancelAfter
method But it would be better if you could describe the task more specifically, otherwise it looks like an XY problem .

Answer 3

Because You didn't say you're using TPL or writing in WinForms or WPF, so I'm assuming it's just plain synchronous code somewhere in the console.
Start a timer above your loop, check the time inside the loop and, upon reaching it, exit the loop through break. On the knee, without checks, but I think you will catch the meaning

var dateTimeStart = DateTime.Now;
const PERIOD = 3 * 60 * 1000;
while(true)
{
    ...
    var dateTimeNow = DateTime.Now;
    var interval = dateTimeNow - dateTimeStart;
    if(interval.Milliseconds > PERIOD)
    {
        break;
    }
}

If the code is synchronous without multithreading, then

var t = DateTime.Now;
var interval = new TimeSpan(0,3,0);
while(DateTime.Now - t < interval)
{
 \\ ...
}

If asynchronous or methods are long, then by timer.
