How do I enumerate an enum in C#? 26 answers

public enum Foos { A, B, C } 

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

Basically?

foreach(Foo in Foos)

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>();

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

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

UPDATED
Some time on, I see a comment that brings me back to my old answer, and I think I'd do it differently now. These days I'd write:

private static IEnumerable<T> GetEnumValues<T>() { // Can't use type constraints on value types, so have to do check like this if (typeof(T).BaseType != typeof(Enum)) { throw new ArgumentException("T must be of type System.Enum"); } return Enum.GetValues(typeof(T)).Cast<T>(); } 
5
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 }

 Enum.GetValues(typeof(Foos)) 

Yes. Use GetValues() method in System.Enum class.
