Enumeration in c#


The enum keyword is used to declare an enumeration, a distinct type consisting of a set of named constants called the enumerator list. It is user defined data types. Every enumeration type has an underlying type, which can be any integral type except char. The default underlying type of the enumeration elements is int. By default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1

How use enum keyword in our program

Example 1:

enum Days { Sat = 1, Sun, Mon, Tue, Wed, Thu, Fri };

protected void Page_Load(object sender, EventArgs e)


   int x = (int)Days.Sun;



Example 2:

In this example we store the enum data in dropdown list

public enum cricketRank


     India = 1,

     SriLanka = 2,

     Pakistan = 3,

     SouthAfrica = 5,

     Englan = 6,


protected void Page_Load(object sender, EventArgs e)


  if (!IsPostBack)


    //Store the name of country in string type array

    string[] names = Enum.GetNames(typeof(cricketRank));

    //Get the values from countryrank enum

    var values = (cricketRank[])Enum.GetValues(typeof(cricketRank));

    for (int i = 0; i < names.Length; i++)

     DropDownList1.Items.Add(new ListItem(names[i], values.ToString()));





Enums have these benefits:

·         They restrict the values that the enum variable can take.

·         They force you to think about all the possible values that the enum can take.

·         They are a constant rather than a number, increasing readability of the source code
