I don't mind multiple exits in such a simple method, hence I'd write:public static bool Equals(this DateTime now, DateTime then, DatePartFlags flags) { if ((flags & DatePartFlags.Ticks) != 0 && now.Ticks != then.Ticks) return false; ... if ((flags & DatePartFlags.Month) != 0...

If you use the logic from your FlagIsSet function, you can remove half of your tests: DatePartFlags equalFlags = DatePartFlags.Ticks; equalFlags |= (now.Year == then.Year) ? DatePartFlags.Year : 0; equalFlags |= (now.Month == then.Month) ? DatePartFlags.Month : 0; ...

I've been paid as a programmer since 1982 with experience in Pascal, and C++ (both self-taught), and began writing Windows programs in 1991 using Visual C++ and MFC. In the 2nd half of 2007, I started writing C# Windows Forms and ASP.Net applications, and have since done WPF, Silverlight, WCF, web services, and Windows services.

My weakest point is that my moments of clarity are too brief to hold a meaningful conversation that requires more than 30 seconds to complete. Thankfully, grunts of agreement are all that is required to conduct most discussions without committing to any particular belief system.
