Is there a way to iterate through all enum values? [duplicate]

Answer 1

.NET 3.5 makes it simple by using extension methods:

enum Color {Red, Green, Blue}

Can be iterated with

Enum.GetValues(typeof(Color)).Cast()

or define a new static generic method:

static IEnumerable GetValues() {
  return Enum.GetValues(typeof(T)).Cast();
}

Keep in mind that iterating with the Enum.GetValues() method uses reflection and thus has performance penalties.
