Time spend running program

How I print in a textbox or at the output the time that the program spend running?

I want it to be displayed into a for-loop, to get how much time each for-loop needs.

You could try:

DateTime dt = DateTime.Now;
for (.......)
{
}
TimeSpan ts = DateTime.Now - dt;
textbox1.Text = ts.TotalMilliseconds.ToString();

or (according to MSDN) if you need better resolution

Stopwatch stopWatch = new Stopwatch();
stopWatch.Start();
for (.......)
{
}
stopWatch.Stop();
textbox1.Text = stopWatch.ElapsedMilliseconds.ToString();

var watch = System.Diagnostics.Stopwatch.StartNew();

for()
{
 // ..
}

watch.Stop();

// Format 00:00:02.0001008
string elapsed = watch.Elapsed.ToString();     

// Milliseconds like 2000 for 2 seconds
string elapsedMs = watch.ElapsedMilliseconds.ToString(); 

System.Diagnostics.Debug.WriteLine(elapsed);

Add these Two Lines- Between your For loop or between the code where you want to test the functinality speed.

 Debug.WriteLine(DateTime.Now.ToLongTimeString());

  --your code

 Debug.WriteLine(DateTime.Now.ToLongTimeString());

You could store the current DateTime on application startup, then create a timer that fires every second. When it fires you get the current DateTime, subtract them to get the TimeSpan and use that to fill your textbox.

something like this: ?

DateTime start = DateTime.UtcNow;

//... processing ...

DateTime end = DateTime.UtcNow;

Syste.Diagnostics.Debug.WriteLine((end - start).ToString());
