How can I convert a Unix timestamp to DateTime and vice versa?

Question

There is this example code, but then it starts talking about millisecond / nanosecond problems.

The same question is on MSDN, Seconds since the Unix epoch in C#<

Answer 1

You can use DateTimeOffset.

For example. I have DateTime object

var dateTime=new DateTime();

If I want convert the it to Unix time stamps, I can be achieve as follows

var unixTimeSeconds= new DateTimeOffset(dateTime).ToUnixTimeSeconds()
