我做了一些扩展以方便枚举的使用。也许有人可以使用它。。。

public static class EnumExtensions
{
    /// <summary>
    /// Gets all items for an enum value.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="value">The value.</param>
    /// <returns></returns>
    public static IEnumerable<T> GetAllItems<T>(this Enum value)
    {
        foreach (object item in Enum.GetValues(typeof(T)))
        {
            yield return (T)item;
        }
    }

    /// <summary>
    /// Gets all items for an enum type.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="value">The value.</param>
    /// <returns></returns>
    public static IEnumerable<T> GetAllItems<T>() where T : struct
    {
        foreach (object item in Enum.GetValues(typeof(T)))
        {
            yield return (T)item;
        }
    }

    /// <summary>
    /// Gets all combined items from an enum value.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="value">The value.</param>
    /// <returns></returns>
    /// <example>
    /// Displays ValueA and ValueB.
    /// <code>
    /// EnumExample dummy = EnumExample.Combi;
    /// foreach (var item in dummy.GetAllSelectedItems<EnumExample>())
    /// {
    ///    Console.WriteLine(item);
    /// }
    /// </code>
    /// </example>
    public static IEnumerable<T> GetAllSelectedItems<T>(this Enum value)
    {
        int valueAsInt = Convert.ToInt32(value, CultureInfo.InvariantCulture);

        foreach (object item in Enum.GetValues(typeof(T)))
        {
            int itemAsInt = Convert.ToInt32(item, CultureInfo.InvariantCulture);

            if (itemAsInt == (valueAsInt & itemAsInt))
            {
                yield return (T)item;
            }
        }
    }

    /// <summary>
    /// Determines whether the enum value contains a specific value.
    /// </summary>
    /// <param name="value">The value.</param>
    /// <param name="request">The request.</param>
    /// <returns>
    ///     <c>true</c> if value contains the specified value; otherwise, <c>false</c>.
    /// </returns>
    /// <example>
    /// <code>
    /// EnumExample dummy = EnumExample.Combi;
    /// if (dummy.Contains<EnumExample>(EnumExample.ValueA))
    /// {
    ///     Console.WriteLine("dummy contains EnumExample.ValueA");
    /// }
    /// </code>
    /// </example>
    public static bool Contains<T>(this Enum value, T request)
    {
        int valueAsInt = Convert.ToInt32(value, CultureInfo.InvariantCulture);
        int requestAsInt = Convert.ToInt32(request, CultureInfo.InvariantCulture);

        if (requestAsInt == (valueAsInt & requestAsInt))
        {
            return true;
        }

        return false;
    }
}

枚举本身必须用FlagsAttribute修饰：

[Flags]
public enum EnumExample
{
    ValueA = 1,
    ValueB = 2,
    ValueC = 4,
    ValueD = 8,
    Combi = ValueA | ValueB
}

某些版本的.NET框架不支持Enum.GetValues。以下是Ideas 2.0的一个很好的解决方法：Compact framework中的Enum.Get Values：

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;
}

与任何涉及反射的代码一样，您应该采取措施确保它只运行一次并缓存结果。

public void PrintAllSuits()
{
    foreach(string suit in Enum.GetNames(typeof(Suits)))
    {
        Console.WriteLine(suit);
    }
}

下面是一个为DDL创建选择选项的工作示例：

var resman = ViewModelResources.TimeFrame.ResourceManager;

ViewBag.TimeFrames = from MapOverlayTimeFrames timeFrame
      in Enum.GetValues(typeof(MapOverlayTimeFrames))
      select new SelectListItem
      {
         Value = timeFrame.ToString(),
         Text = resman.GetString(timeFrame.ToString()) ?? timeFrame.ToString()
      };

我知道这有点乱，但如果你喜欢一句话，这里有一句：

((Suit[])Enum.GetValues(typeof(Suit))).ToList().ForEach(i => DoSomething(i));

我想这对你有帮助。

public class Program
{

    public static List<T> GetEnamList<T>()
    {
        var enums = Enum.GetValues(typeof(T)).Cast<T>().Select(v => v).ToList();
        return enums;
    }
    private void LoadEnumList()
    {
        List<DayofWeek> dayofweeks = GetEnamList<DayofWeek>();

        foreach (var item in dayofweeks)
        {
            dayofweeks.Add(item);
        }
    }
}

    public enum DayofWeek
    {
        Monday,
        Tuesday,
        Wensday,
        Thursday,
        Friday,
        Sturday,
        Sunday
    }
