Enumeration with subtypes c#-CodePudding

First of all perhaps this is a problem due to a bad design. Here is my scenario simplified:

I have a class call Day it represent a day of the year, with its date and the "type" of day.

public class Day{
 Date Key;
 TypeDay type;
}

So the day can be a worked day or a holiday one:

public enum TypeDay{
    Work,
    Holiday
}

So far so good, but now holiday days can have subtypes like paidDays and NonPaid days I would need another enum to represent that subtypes or add all subtypes in a single enum (in this example i have 2 days and 2 subtypes but in real live i have 50-40 types) so this get so messy .

 public enum TypeDay{
        Work,
        Holiday_NonPaid
        Holiday_Paid
    }

How can i build this in a better way,any ideas?

CodePudding user response：

Enumerators didn't support that behaviour, If you feel that a structure like that is needed you can 'simulate' it with a static class

static class TypeDay
{
    public const int Work = 0;

    public static class Holiday
    {
        public const int Paid = 1;
        public const int NonPaid = 2;
    }
}

CodePudding user response：

You could use flags to treat 'paid' and 'holiday' as independent properties of the enum:

[Flags]
public enum TypeDay{
        Na = 0,
        Work = 1,
        Holiday = 2,     
        Holiday_NonPaid = Holiday,
        Holiday_Paid = Holiday | Work 
    }

This assumes a workday is paid. This lets you either check the exact type, or if the day has a specific flag, isHoliday = type.HasFlag(TypeDay.Holiday) or isPaid = type.HasFlag(TypeDay.Work).

But there are other approaches, like using classes instead of enums.The most appropriate approach will depend on the exact use case and what you want to do with the values.
