stopwatch

I'm totally confused between these 4. What is the difference between ElapsedMilliseconds (long), ElapsedTicks (long), Elapsed.TotalMilliseconds (double) and Elapsed.Milliseconds (int)? I have a function { Stopwatch sw = new Stopwatch(); sw.Start(); MyTimeConsumingAction(); sw.Stop(); sw.//what? } How do I get the correct time consumed by my long running process from elapsed property of Stopwatch object in milliseconds? Edit: I tried msdn documentation but it isn't anything detailed there.. Dr. ABT Elapsed.TotalMilliseconds (double) returns the total number of whole and fractional milliseconds

I need an accurate timer, and DateTime.Now seems not accurate enough. From the descriptions I read, System.Diagnostics.Stopwatch seems to be exactly what I want. But I have a phobia. I'm nervous about using anything from System.Diagnostics in actual production code. (I use it extensively for debugging with Asserts and PrintLns etc, but never yet for production stuff.) I'm not merely trying to use a timer to benchmark my functions - my app needs an actual timer. I've read on another forum that System.Diagnostics.StopWatch is only for benchmarking, and shouldn't be used in retail code, though

Is it normal behaviour that Stopwatch can return negative values? Code sample below can be used to reproduce it. while (true) { Stopwatch sw = new Stopwatch(); sw.Start(); sw.Stop(); if (sw.ElapsedMilliseconds < 0) Debugger.Break(); } The only place where I can reproduce negative numbers is my virtual machine (hosted by Hyper-V on a 8-core machine) This is a bug . It doesn't seem to have a lot of attention around it, through, so I'd suggesting following up with that report. The uninspiring workaround appears to be to ignore negative values: long elapsedMilliseconds = Math.Max(0, stopwatch

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? Omar To avoid future problems with a timer, here is the right code: timer = new

How accurate is System.Diagnostics.Stopwatch ? I am trying to do some metrics for different code paths and I need it to be exact. Should I be using stopwatch or is there another solution that is more accurate. I have been told that sometimes stopwatch gives incorrect information. CMS Why you don't profile your code instead of focusing on micro-benchmarks? There are some good Open Source profilers like: NProf Prof-It for C# NProfiler ProfileSharp Thomas Maierhofer I've just written an article that explains how a test setup must be done to get an high accuracy (better than 0.1ms) out of the
