C# Example of GetNames and GetValues methods of System.Enum class

Example of GetNames and GetValues to get all named constants and their values of an enumeration (enum)

enum DayOfWeek
{
    Monday,
    Tuesday,
    Wednesday,
    Thursday,
    Friday,
    Saturday,
    Sunday
}

class EnumExample
{
    static void Main(string[] args)
    {
        // loop through all names of DayOfWeek enum
        // System.Enum class provides a static method called GetNames
        // that returns an array of the names of the constants in a specified enumeration.
        foreach (string day in Enum.GetNames(typeof(DayOfWeek)))
        {
            Console.WriteLine(day);
        }
        // LINQ for fun, using System.Linq namespace
        Console.WriteLine("------------------");
        Enum.GetNames(typeof(DayOfWeek)).ToList().ForEach(day => Console.WriteLine(day));
        // loop through all values of DayOfWeek enum
        Console.WriteLine("------------------");
        Enum.GetValues(typeof(DayOfWeek))
            .Cast<DayOfWeek>().ToList() // cast Enumerable to List
            .ForEach(day => Console.WriteLine($"{day} = {(int)day}"));
    }
}
