Part 46 - C# Tutorial - Enums Example


The program that we have started in Part 45 is now rewritten using Gender enum, which makes it more readable and maintainable.

using System;
public class Enums
{
    public static void Main()
    {
        Customer[] customers = new Customer[3];
        customers[0] = new Customer()
        {
            Name = "Mark",
            Gender = Gender.Male
        };
        customers[1] = new Customer()
        {
            Name = "Mary",
            Gender = Gender.Female
        };
        customers[2] = new Customer()
        {
            Name = "Sam",
            Gender = Gender.Unknown
        };
        foreach (Customer customer in customers)
        {
            Console.WriteLine("Name = {0} && Gender = {1}", customer.Name, GetGender(customer.Gender));
        }
    }


    public static string GetGender(Gender gender)
    {
        // The swicth here is now more readable and maintainable because 
        // of replacing the integral numbers with Gender enum
        switch (gender)
        {
            case Gender.Unknown:
                return "Unknown";
            case Gender.Male:
                return "Male";
            case Gender.Female:
                return "Female";
            default:
                return "Invalid Data for Gender";
        }
    }
}


public enum Gender
{
    Unknown = 0,
    Male = 1,
    Female = 2
}


public class Customer
{
    public string Name { get; set; }
    public Gender Gender { get; set; }
}
