Get elapsed time since application start

Question

I am porting an app from ActionScript3.0 (Flex) to C# (WPF).AS3.0 has got a handy utility called getTimer() which returns time since Flash Virtual machine start in milliseco

Answer 1

Process.GetCurrentProcess().StartTime is your friend.

..so to get elapsed time since start:

DateTime.UtcNow - Process.GetCurrentProcess().StartTime.ToUniversalTime()

alternatively, if you need more definition, System.Diagnostics.Stopwatch might be preferable. If so, start a stopwatch when your app starts:

Stopwatch sw = Stopwatch.StartNew();

then query the sw.Elapsed property during your execution run.
