Bitmask c#

[Flags]
public enum Days
{
    None = 0,	//must have a specified 0
    Sunday = 1 << 0,	//1
    Monday = 1 << 1,	//2
    Tuesday = 1 << 2,	//4
    Wednesday = 1 << 3,	//8
    Thursday = 1 << 4,	//16
    Friday = 1 << 5,	//32
    Saturday = 1 << 6,	//64
    
    Workdays = Monday | Tuesday | Wednesday | Thursday | Friday,	// 0111110
    Vacationdays = Saturday | Sunday,								// 1000001
    AllDays = Workdays | Vacationdays								// 1111111
}

//Example:
public Days myDays = Days.Wednesday | Days.Friday;	//myDays = 0101000
public bool containsTuesday = (myDays & Days.Tuesday) == Days.Tuesday ? true : false; // 0101000 & 0000100 = 0000000 (not 0000100, so expression is FALSE)
Console.WriteLine(containsTuesday); //output: false

//Operator cheat-sheet:
// & - apply mask
// | - combine
// ^ - combine/toggle, get difference
