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
{

Some versions of the .NET framework do not support Enum.GetValues. Here's a good workaround from Ideas 2.0: Enum.GetValues in Compact Framework:

public Enum[] GetValues(Enum enumeration)
{
    FieldInfo[] fields = enumeration.GetType().GetFields(BindingFlags.Static | BindingFlags.Public);
    Enum[] enumerations = new Enum[fields.Length];

    for (var i = 0; i < fields.Length; i++)
        enumerations[i] = (Enum) fields[i].GetValue(enumeration);

    return enumerations;
}

As with any code that involves reflection, you should take steps to ensure it runs only once and results are cached.
