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

The OP asked for How to get an array of all enum values in C# ?

What if you want to get an array of selected enum values in C# ?

Your Enum

    enum WeekDays 
    {
        Sunday, 
        Monday,
        Tuesday
    }

If you want to just select Sunday from your Enum.

  WeekDays[] weekDaysArray1 = new WeekDays[] { WeekDays.Sunday };

  WeekDays[] weekDaysArray2 = Enum.GetValues(typeof(WeekDays)).Cast<WeekDays>().Where
  (x => x == WeekDays.Sunday).ToArray();

Answer 2

You can use

Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>().ToArray();

This returns an array!

Answer 3

Something little different:

typeof(SomeEnum).GetEnumValues();

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.
