c# - Timer affidabile in un'applicazione console

original title: "c# - Reliable timer in a console application"

I am aware that in .NET there are three timer types (see Comparing the Timer Classes in the .NET Framework Class Library). I have chosen a threaded timer as the other types can drift if the main thread is busy, and I need this to be reliable.

The way this timer works in the control of the timer is put on another thread so it can always tick along with the work begin completed on the parent thread when it is not busy.

The issue with this timer in a console application is that while the timer is ticking along on another thread the main thread is not doing anything to the application closes.

I tried adding a while true loop, but then the main thread is too busy when the timer does go off.



Sono consapevole che in .NET esistono tre tipi di timer (consultare Confronto delle classi di timer nella libreria di classi di .NET Framework). Ho scelto un timer con thread in quanto gli altri tipi possono andare alla deriva se il t principale ...

    You can use something like Console.ReadLine() to block the main thread, so other background threads (like timer threads) will still work. You may also use an AutoResetEvent to block the execution, then (when you need to) you can call Set() method on that AutoResetEvent object to release the main thread. Also ensure that your reference to Timer object doesn't go out of scope and garbage collected.
