Hi,

Wanted to know if thread timer object continues to fire even if the task being performed it's done.

Example:

C#

System.Threading.Timer t = new System.Threading.Timer(MyMethod,null,0,1000);

void MyMethod(object o)
{
  // task that completes at varying times but NEVER less than the timer's interval
}

Yup. The timer fires a TICK event, then restarts immediately. It does not wait for the task to complete, it just fires an event.

If you want it to stop, then use the stop routine.

In case you to run your next task only after finishing the current task is over, try to set a global flag and within timer do new the task based on the status of flag.

Solution 3

The simple fact that a timer keeps firing even when the tick handler is being processed makes the code using timers vulnerable. It's much better to use threads whenever possible avoiding timers.
