How do I measure how long a function is running?
.net, c#, performance, stopwatch, timer
Solution
To avoid future problems with a timer, here is the right code:
timer = new Timer();
timer.Tick += new EventHandler(timer_Tick);
timer.Interval = 1; //set interval on 1 milliseconds
timer.Enabled = true; //start the timer
Result result = new Result();
result = new GeneticAlgorithms().TabuSearch(parametersTabu, functia);
timer.Enabled = false; //stop the timer
private void timer_Tick(object sender, EventArgs e)
{
counter++;
btnTabuSearch.Text = counter.ToString();
}
But it's the wrong aproach. You must use the Stopwatch (System.Diagnostic) class because it's a High resolution timer and the word Diagnostic says everything.
So try this:
Stopwatch timer = Stopwatch.StartNew();
Result result = new Result();
result = new GeneticAlgorithms().TabuSearch(parametersTabu, functia);
timer.Stop();
TimeSpan timespan = timer.Elapsed;
btnTabuSearch.Text = String.Format("{0:00}:{1:00}:{2:00}", timespan.Minutes, timespan.Seconds, timespan.Milliseconds / 10);
Problem
I want to see how long a function is running. So I added a timer object on my form, and I came out with this code: ``` private int counter = 0; // Inside button click I have: timer = new Timer(); timer.Tick += new EventHandler(timer_Tick); timer.Start(); Result result = new Result(); result = new GeneticAlgorithms().TabuSearch(parametersTabu, functia); timer.Stop(); ``` And: ``` private void timer_Tick(object sender, EventArgs e) { counter++; btnTabuSearch.Text = counter.ToString(); } ``` But this is not counting anything. Why?
