Singular or plural for enumerations?

Question

Do you use singular or plural for enumerations? I think it makes best sense with plural in the declaration

enum Weekdays
{
    Monday,
    Tuesday,
    Wednesday         


        

Answer 1

In the .NET Framework, most "normal" enums (e.g. DayOfWeek) have singular names and flag enums (e.g. StringSplitOptions, BindingFlags) have plural names. It makes sense, since a value of a flag enum can represent multiple items but for a non-flag enum, it can only represent a single item.
