Array of enum in C#

Array of enum means array which contains only symbolic constants of that enum.

using System;

namespace arrayDemo

{

    class Program

    {

        enum Color { Red, Green, Blue };

        static void Main(string[] args)

        {

            Color[] arr = new Color[3];

            arr[0] = Color.Green;

            arr[1] = Color.Red;

            arr[2] = Color.Blue; 

            //printing value of each element in the array

            foreach (int element in arr)

            {

                Console.WriteLine(element); 

            }

            Console.ReadKey();

        }

    }

}

In the above example array of enum arr can keep only Color.Red, Color.Green and Color.Blue

For any other value we have first type cast into Color. For example:

arr[0] = (Color)5;
