Java System.currentTimeMillis() equivalent in C#


c# java .net datetime

An alternative:

private static readonly DateTime Jan1st1970 = new DateTime    (1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);public static long CurrentTimeMillis(){    return (long) (DateTime.UtcNow - Jan1st1970).TotalMilliseconds;}

c# java .net datetime

A common idiom in Java is to use the currentTimeMillis() for timing or scheduling purposes, where you're not interested in the actual milliseconds since 1970, but instead calculate some relative value and compare later invocations of currentTimeMillis() to that value.

If that's what you're looking for, the C# equivalent is Environment.TickCount.

c# java .net datetime

If you are interested in TIMING, add a reference to System.Diagnostics and use a Stopwatch.

For example:

var sw = Stopwatch.StartNew();...var elapsedStage1 = sw.ElapsedMilliseconds;...var elapsedStage2 = sw.ElapsedMilliseconds;...sw.Stop();
