Return start and end of year given any year

Question

I need two or one (out) C# method that will take any datetime and return the start date of year and end date of year for that year.

What do you mean by start date of year? It will always be Jan 1 and Dec 31 right? — jfs, May 23 '10 at 10:06
The start date is Jan 1 and the end date is Dec 31. Am I missing something? — Marcelo Cantos, May 23 '10 at 10:07

{
    b = new DateTime(d.Year, 1, 1);
    e = new DateTime(d.Year, 12, 31);

For 6 years I had typo in the answer, got 20 points, and nobody noticed that. Nice :-) – nothrow May 05 '16 at 14:58

also this will not include 12/31 if the time is important, than should be e = ...AddTicks(-1).AddDays(1) – Arsen Mkrtchyan Apr 03 '19 at 13:21

DateTime startDate = new DateTime(year, 1, 1);
DateTime endDate = new DateTime(year, 12, 31);
