time steps in sub and write value to console

Some sub's in my VB.Net program take a lot of time, and I do not understand why. I'd like to start a counter at the beginning of the sub and write the Milliseconds passed for each row in the console.

I tried using a Timer and resetting it after each row but it was too threadintesive. Is there a better way, using the system date/time in order to get a quite precise reading of the time each step takes?

Thank you

Solution

  • Use the Stopwatch class. However doing so for each row seems a bit impossible... That means you would have to add for example Console.WriteLine() after every row.

    Example usage:

    Dim sw As New Stopwatch

sw.Start()
yourMethod()
sw.Stop()

Console.WriteLine(String.Format("{0} ms", sw.Elapsed.TotalMilliseconds))
