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 such a list? e.g. If I have an enum:

public enum Enumnum { TypeA, TypeB, TypeC, TypeD }

how would I be able to get a List<Enumnum> that contains { TypeA, TypeB, TypeC, TypeD }?

Answer 1

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(); 

Answer 2

Try this code:

Enum.GetNames(typeof(Enumnum)); 

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

Answer 3

Enum.GetValues(typeof(Enumnum));

returns an array of the values in the Enum.

Answer 4

You may want to do like this:

public enum Enumnum { 
            TypeA = 11,
            TypeB = 22,
            TypeC = 33,
            TypeD = 44
        }

All int values of this enum is 11,22,33,44.

You can get these values by this:

var enumsValues = Enum.GetValues(typeof(Enumnum)).Cast<Enumnum>().ToList().Select(e => (int)e);

string.Join(",", enumsValues) is 11,22,33,44.
