.NET Windows Service with timer stops responding

Question

I have a windows service written in c#. It has a timer inside, which fires some functions on a regular basis. So the skeleton of my service:

public partial cl         


        

Answer 1

Like many respondents have pointed out exceptions are swallowed by timer. In my windows services I use System.Threading.Timer. It has Change(...) method which allows you to start/stop that timer. Possible place for exception could be reentrancy problem - in case when tickTack_Elapsed executes longer than timer period. Usually I write timer loop like this:

    void TimeLoop(object arg)
    {
        stopTimer();

        //Do some stuff

        startTimer();
    }

You could also lock(...) your main loop to protect against reentrancy.
