How to iterate over values of an Enum having flags?

static IEnumerable<Enum> GetFlags(Enum input)
{
    foreach (Enum value in Enum.GetValues(input.GetType()))
        if (input.HasFlag(value))
            yield return value;
}

Here is a Linq solution to the problem.

public static IEnumerable<Enum> GetFlags(this Enum e)
{
      return Enum.GetValues(e.GetType()).Cast<Enum>().Where(e.HasFlag);
}
