Question

I’d like to do some basic profiling of my code, but found that the DateTime.Now in C# only have a resolution of about 16 ms. There must be better time keeping constructs that I haven’t yet found.

Answer 1

Here is a sample bit of code to time an operation:

Dim sw As New Stopwatch() sw.Start() //Insert Code To Time sw.Stop() Dim ms As Long = sw.ElapsedMilliseconds Console.WriteLine('Total Seconds Elapsed: ' & ms / 1000) 

EDIT:

And the neat thing is that it can resume as well.

Stopwatch sw = new Stopwatch(); foreach(MyStuff stuff in _listOfMyStuff) {     sw.Start();     stuff.DoCoolCalculation();     sw.Stop(); } Console.WriteLine('Total calculation time: {0}', sw.Elapsed); 

The System.Diagnostics.Stopwatch class will use a high-resolution counter if one is available on your system.
