How can I find out the number of seconds since 1970 using DateTime in C#

Question

I am currently using this code:

 var stringSecsNow = DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds.ToString();

But is there some other way. I seem to recall in another language that there was an easier way to do this?

Answer 1

Almost same but looks easier.

DateTime PreviousDateTime = new DateTime(1970, 1, 1);
var stringSecsNow = (DateTime.UtcNow - PreviousDateTime).TotalSeconds.ToString();
