Question

I have the input 15:20:30

I want to convert to seconds.

Answer 1

Seeing as though you haven’t specified the question properly I have interpreted it to represent 15 hours 20 minutes and 30 seconds, as opposed to DateTime.Now. (Obviously this is the same as “How many seconds since midnight”)

  TimeSpan MySpan = new TimeSpan(15, 20, 30);
  MySpan.TotalSeconds;

Although if you’re only wanting the Seconds from the current DateTime.Now (this is not the TotalSeconds, just the current minutes seconds), just use:

  DateTime.Now.Second
