C# Memoization of functions with arbitrary number of arguments [closed]

Answer 1

StopWatch.Stop does not reset the stopwatch so you are accumulating time on each start/stop.

For example

  Stopwatch sw = new Stopwatch();

  sw.Start();
  System.Threading.Thread.Sleep(100);
  sw.Stop();
  Debug.WriteLine(sw.ElapsedTicks);

  sw.Start();
  System.Threading.Thread.Sleep(100);
  sw.Stop();
  Debug.WriteLine(sw.ElapsedTicks);

Gives the following results

228221
454626

You can use StopWatch.Restart (Framework 4.0) to restart the stopwatch each time, or if not Framework 4.0, you can use StopWatch.Reset to reset the stopwatch.
