Can You Loop Through All Enum Values? c#

Question

Hi there,

public enum Foos
{
    A,
    B,
    C
}

Is there a way to loop through the possible values of Foo?

Basically?

foreach(Foo in Foos)

Answer 1

foreach(Foos foo in Enum.GetValues(typeof(Foos))

Edit:Plural Foos

Answer 2

Yes you can use the GetValues method

var values = Enum.GetValues(typeof(Foos));

Or the typed version

var values = Enum.GetValues(typeof(Foos)).Cast<Foos>();

I long ago added a helper function to my private library for just such an occasion

public static class EnumUtil {
  public static IEnumerable<T> GetValues<T>() {
    return Enum.GetValues(typeof(T)).Cast<T>();
  }
}

Usage:

var values = EnumUtil.GetValues<Foos>();

Answer 3

Yes. Use "GetValues" method in System.Enum class.

Answer 4

foreach (EMyEnum val in Enum.GetValues(typeof(EMyEnum)))
{
   Console.WriteLine(val);
}

    /// <summary>
    /// Returns a generic list of all values for an enum.
    /// Taken from http://devlicio.us/blogs/joe_niland/archive/2006/10/10/Generic-Enum-to-List_3C00_T_3E00_-converter.aspx

    public static IList<T> EnumToList<T>()
    {
        Type enumType = typeof(T);

        // Can't use type constraints on value types, so have to do check like this
        if (enumType.BaseType != typeof(Enum))
            throw new ArgumentException("T must be of type System.Enum");

        Array enumValArray = Enum.GetValues(enumType);

        List<T> enumValList = new List<T>(enumValArray.Length);

        foreach (int val in enumValArray)
        {
            enumValList.Add((T)Enum.Parse(enumType, val.ToString()));
        }

        return enumValList;
    }

    static void Main(string[] args)
    {
        foreach (int value in Enum.GetValues(typeof(DaysOfWeek)))
        {
            Console.WriteLine(((DaysOfWeek)value).ToString());

        }

        foreach (string value in Enum.GetNames(typeof(DaysOfWeek)))
        {
            Console.WriteLine(value);

        }
        Console.ReadLine();

    }

    public enum DaysOfWeek
    {
        monday,
        tuesday,
        wednesday
    }
}
