# millisecond - elapsed ticks c#

## Difference between ElapsedTicks, ElapsedMilliseconds, Elapsed.Milliseconds and Elapsed.TotalMilliseconds?(C#) (3)

Elapsed.TotalMilliseconds (double) returns the total number of whole and fractional milliseconds elapsed since inception

e.g. a stopwatch stopped at 1.23456 seconds would return 1234.56 in this property. See TimeSpan.TotalMilliseconds on MSDN

Elapsed.Milliseconds (int) returns the number of whole milliseconds in the current second

e.g. a stopwatch at 1.234 seconds would return 234 in this property. See TimeSpan.ElapsedMilliseconds

ElapsedTicks (long) returns the ticks since start of the stopwatch.

In the context of the original question, pertaining to the Stopwatch class, ElapsedTicks is the number of ticks elapsed. Ticks occur at the rate of Stopwatch.Frequency, so, to compute seconds elapsed, calculate: numSeconds = stopwatch.ElapsedTicks / Stopwatch.Frequency.

The old answer defined ticks as the number of 100 nanosecond periods, which is correct in the context of the DateTime class, but not correct in the context of the Stopwatch class. See Stopwatch.ElapsedTicks on MSDN.

ElapsedMilliseconds returns a rounded number to the nearest full millisecond, so this might lack precision Elapsed.TotalMilliseconds property can give.

Elapsed.TotalMilliseconds is a double that can return execution times to the partial millisecond while ElapsedMilliseconds is Int64. e.g. a stopwatch at 0.0007 milliseconds would return 0 , or 1234.56 milliseconds would return 1234 in this property. So for precision always use Elapsed.TotalMilliseconds.

See Stopwatch.ElapsedMilliseconds on MSDN for clarification.

Best regards,

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..

`Elapsed` is `TimeSpan`. If you want to display time, then just `Elapsed.ToString()` should do that

in a short explanation from msdn:

``````ElapsedMilliseconds
``````

This property represents elapsed time rounded down to the nearest whole millisecond value. For higher precision measurements, use the Elapsed or ElapsedTicks properties.

``````ElapsedTicks
``````

This property represents the number of elapsed ticks in the underlying timer mechanism. A tick is the smallest unit of time that the Stopwatch timer can measure. Use the Frequency field to convert the ElapsedTicks value into a number of seconds.

``````Elapsed
``````

Use the Elapsed property to retrieve the elapsed time value using TimeSpan methods and properties. For example, you can format the returned TimeSpan instance into a text representation, or pass it to another class that requires a TimeSpan parameter.
