ElapsedTicks & Elapsed.Ticks are properties of Stopwatch, which I think should be same. And in case they are same, why they should give different outputs ?
Code :
See http://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch.elapsedticks.aspx:
Note Stopwatch ticks are different from DateTime.Ticks. Each tick in the DateTime.Ticks value represents one 100-nanosecond interval. Each tick in the ElapsedTicks value represents the time interval equal to 1 second divided by the Frequency.
