Question

I have a function that returns the difference between 2 DateTime’s in seconds. However, in certain cases its not working correctly and I’m not sure why.

I.E.:

Debug.WriteLine(DateTime.Parse("7/22/2010 9:52:39 AM").Subtract(DateTime.Parse("7/22/2010 8:58:38 AM")).Seconds, "WTF");

The above code returns 1 … obviously there’s more than a 1 second difference between the dates above.

Answer 1

Use the TimeSpan.TotalSeconds property instead of .Seconds:

Debug.WriteLine(DateTime.Parse("7/22/2010 9:52:39 AM").Subtract(DateTime.Parse("7/22/2010 8:58:38 AM")).TotalSeconds, "WTF");
