esoteric struct vs class question

Mark

I know this is pretty esoteric but if all you have is a bunch of static
methods, which is the most efficient - a struct or a static class? Or are
they about the same?

Thanks
Mark

I would not expect there to be any difference. However, inasmuch as the
C# programming reference suggests making a type a class if you expect it
to be something more than a very simple data structure, it seems to me
that a static class is generally a better choice than a static struct.

If you're never actually making an instance of the type though, I don't
think there should be any efficiency difference at all, one way or the
other.

Hi Mark,

I think for defining static utility methods, there won't have much
difference on performance between struct or class. The difference between
class and struct is mainly focus on OO encapsulation and value/reference
type behavior perspective. IMO, I'll prefer using class if it is a utility
class that may contains many helper static functions. I will only use
struct for many trivial types that is better to defined as value type(not
used as reference).

Sincerely,

If you're writing C#, I'd use a class for the simple reason that you
can then declare it as static, which makes it clear that you don't
*want* anyone to create instances of it, and indeed the compiler will
help you to make sure that all your methods are static etc.
