How to enumerate an enum

Question

How can you enumerate an enum in C#?

E.g. the following code does not compile:

public enum Suit
{         


        

Answer 1

Just by combining the top answers, I threw together a very simple extension:

public static class EnumExtensions
{
    /// 

    /// Gets all items for an enum value.
    /// 
    /// 
    /// The value.
    /// 
    public static IEnumerable GetAllItems(this T value) where T : Enum
    {
        return (T[])Enum.GetValues(typeof (T));
    }
}

It is clean, simple, and, by @Jeppe-Stig-Nielsen's comment, fast.
