How to get an array of all enum values in C#?

Question

I have an enum that I\'d like to display all possible values of. Is there a way to get an array or list of all the possible values of the enum instead of manually creating s

Answer 1

If you prefer a more generic way, here it is. You can add up more converters as per your need.

    public static class EnumConverter
    {

        public static string[] ToNameArray<T>()
        {
            return Enum.GetNames(typeof(T)).ToArray();
        }

        public static Array ToValueArray<T>()
        {
            return Enum.GetValues(typeof(T));
        }

        public static List<T> ToListOfValues<T>()
        {
            return Enum.GetValues(typeof(T)).Cast<T>().ToList();
        }


        public static IEnumerable<T> ToEnumerable<T>()
        {
            return (T[])Enum.GetValues(typeof(T));
        }

    }

Sample Implementations :

   string[] roles = EnumConverter.ToStringArray<ePermittedRoles>();
   List<ePermittedRoles> roles2 = EnumConverter.ToListOfValues<ePermittedRoles>();
   Array data = EnumConverter.ToValueArray<ePermittedRoles>();

Answer 2

Enum.GetValues(typeof(Enumnum));

returns an array of the values in the Enum.

Answer 3

with this:

string[] myArray = Enum.GetNames(typeof(Enumnum));

and you can access values array like so:

Array myArray = Enum.GetValues(typeof(Enumnum));

Answer 4

also you can use

var enumAsJson=typeof(SomeEnum).Name + ":[" + string.Join(",", Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>().Select(e => e.ToString())) + "]";

for get all elements in enum as json format.

Answer 5

Try this code:

Enum.GetNames(typeof(Enumnum));

This return a string[] with all the enum names of the chosen enum.

Answer 6

This gets you a plain array of the enum values using Enum.GetValues:

var valuesAsArray = Enum.GetValues(typeof(Enumnum));

And this gets you a generic list:

var valuesAsList = Enum.GetValues(typeof(Enumnum)).Cast<Enumnum>().ToList();
