display name & value of ENUMs?

JesseSTL · February 5th, 2011, 06:06 PM

I am trying to teach myself C# using books.

I would like to display the name and the value of a collection of enums.

For instance:

Code:

        public enum Days { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday };
     foreach (x in Days) {
         Console.Write ("{0} {1} ", x.name, x.value);
         }

should display: Sunday 0 Monday 1 Tuesday 2 Wednesday 3 Thursday 4 Friday 5 Saturday 6

What do I replace the "x in Days" with to get these values?

Thanks in Advance

Enums have a default type of int. So, for instance, Sunday will have a value of 0 assigned to it (you can change what the value is if you like). There is an example in the book to shows how to do this (page 105). Here would be come code for your example:

Code:

namespace ForumExample
{
    enum days
    { 
        sunday,
        monday,
        tuesday,
        wednesday,
        thursday,
        friday,
        saturday
    }

    class Program
    {
        static void Main(string[] args)
        {
            int daysInt;
            string daysString;
            days myDay = days.sunday;
            daysInt = (int)myDay;
            daysString = Convert.ToString(myDay);
            Console.WriteLine("{0} {1}", daysInt, daysString);
            Console.ReadKey();
        }
    }
}

This will generate the info for Sunday. Not sure if you can use a foreach statement on an enum.

Code:

            foreach (int value in Enum.GetValues(typeof(Days)))
            {
                Console.Write("{0} {1} ", Enum.GetName(typeof(Days), value), value);
            }
