enums bitwise values.

[Ibrahim.]

Hello,

I have a enum structure like this ;

[Flags]
public enum days
{
Sun=1,
Mon=2,
Tue=4,
Wed=8,
Thur=16,
Fri=32,
Sat=64
}

now i sum only sun & fri & save to database table field

int daysSelected = (int) days.sun | days.fri

now i want to get the enum values from daysSelected again ?

thanks.

bool sunset = (daysselected & days.sun) != 0;

If I understand you correctly, you want to change the integer back to an
enumeration value (or combination)?

If so, just cast the integer:

days selected = (days)daysSelected;

If you output this as a string it will be comma-separated. Check out
