using System;

​

//An enumeration type (also named an enumeration or an enum) provides an efficient way to define a set of named integral constants 

//that may be assigned to a variable. 

​

//Classic enum:

    public enum Day 

    { 

        Sunday, 

        Monday, 

        Tuesday, 

        Wednesday,   

        Thursday, 

        Friday, 

        Saturday 

    }

​

//These values will always stay the same. 

​

​

//Here's how you might print this out.

Console.WriteLine(Day.Wednesday);

Console.WriteLine("The best day of the week is {0}.", Day.Friday);

​

//Here's how I might check the value by "casting" it to an int.

int FirstWorkDay = (int)Day.Monday;

Console.WriteLine("Notice how this one prints a number for Monday: {0}", FirstWorkDay);

​

Console.WriteLine("{0} used to be the best day for tv.", Day.Thursday);

​

//You can also set a variable similar to how you create an object.

// <enum name> variableName = EnumName.

Day yesterday = Day.Tuesday;

Console.WriteLine("Yesterday was {0}", yesterday);

​

//You try it. Print "Wednesday is the 3rd day of the work week."

​

Day today = Day.Wednesday;

​

​

​

//You can verify the underlying numeric values by "casting" to the underlying type. 

int dayNumber = (int)today;

Console.WriteLine("{0} is the {1}rd day of the work week.", today, dayNumber);

​

//Here's how you might create variable to pass around that turns an enum to a string. This one turns it into a string.

string dayName = ((Day) 1).ToString();

Console.WriteLine(dayName);

​

​

​

//Practice: Create 2 enums. One for the card types in a deck of cards and one for the SuitTypes.  

​

​

​

//Create an object 

Cards hand = new Cards();

​

//Call the method. To pass in the enum, you give the classname(Cards), the enum name(RankType), and the type name(Ace).

// 

hand.GetCard(Cards.RankType.Ace, Cards.SuitType.Hearts);

​

class Cards {

​

    public enum SuitType 

    {

        Spades,

        Hearts,

        Diamonds,

        Clubs

    };

​

​

    public enum RankType 

    {

        Ace,

        Two,

        Three,

        Four,

        Five,

        Six,

        Seven,

        Eight,

        Nine,

        Ten,

        Jack,

        Queen,

        King,

    };

​

    public RankType rank {get ; set; }

    //Method

    public void GetCard(RankType rank, SuitType suit)

    {

        Console.WriteLine("I was dealt the {0} of {1}.", rank, suit);

    }
