Shanti C# - OOP Exercise: (2) USING ENUMERATION

Hi All,

I searched for how to use enumeration and wrote the below code.
But I'm not sure whether this is a right way or not.
If someone find another ways or good websites, please let me know:D

Form

        private void btnDisplay1_Click(object sender, EventArgs e)
        {
            SimpleCardEnum card = new SimpleCardEnum(int.Parse(txtCardValue.Text));
            lblResult.Text = card.getInfo();
        }

        private void btnDisplay2_Click(object sender, EventArgs e)
        {
            SimpleCardEnum card = new SimpleCardEnum(txtCardName.Text.ToUpper());
            lblResult.Text = card.getInfo();
        }

        private void btnDisplayAll_Click(object sender, EventArgs e)
        {
            SimpleCardEnum card = new SimpleCardEnum();
            lblResult.Text = card.getAllCardName();
        }

Class

    public class SimpleCardEnum
    {
        //instance variables
        private int cardValue;
        //static fields
        public static int CardInASet = 13;
        //enumerations
        public enum CardName
        {
            ACE = 1,
            TWO = 2,
            THREE = 3,
            FOUR = 4,
            FIVE = 5,
            SIX = 6,
            SEVEN = 7,
            EIGTH = 8,
            NINE = 9,
            TEN = 10,
            JACK = 11,
            QUEEN = 12,
            KING = 13
        }
        //properties
        public int CardValue
        {
            get { return cardValue; }
            set { cardValue = value; }
        }
        //constructors
        public SimpleCardEnum()
        {
            cardValue = 1;
        }
        public SimpleCardEnum(int cv)
        {
            cardValue = cv;
        }
        public SimpleCardEnum(string cn)
        {
            cardValue = (int)Enum.Parse(typeof(SimpleCardEnum.CardName), cn);
        }
        //methods
        public string getCardName()
        {
            return Enum.GetName(typeof(SimpleCardEnum.CardName), cardValue);
        }
        public string getInfo()
        {
            return getCardName() + " " + cardValue;
        }
        public string getAllCardName()
        {
            string names = "";
            foreach (string name in Enum.GetNames(typeof(SimpleCardEnum.CardName)))
            {
                names += name + ", ";
            }
            return names;
        }
     }
