对在System.Enum类中使用GetValues（）方法。

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

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

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

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
}
