你可以使用下面的泛型方法:

public static List<T> GetItemsList<T>(this int enums) where T : struct, IConvertible
{
    if (!typeof (T).IsEnum)
    {
        throw new Exception("Type given must be an Enum");
    }

    return (from int item in Enum.GetValues(typeof (T))
            where (enums & item) == item
            select (T) Enum.Parse(typeof (T), item.ToString(new CultureInfo("en")))).ToList();
}

下面是我喜欢的使用LINQ的方式:

public class EnumModel
{
    public int Value { get; set; }
    public string Name { get; set; }
}

public enum MyEnum
{
    Name1=1,
    Name2=2,
    Name3=3
}

public class Test
{
        List<EnumModel> enums = ((MyEnum[])Enum.GetValues(typeof(MyEnum))).Select(c => new EnumModel() { Value = (int)c, Name = c.ToString() }).ToList();

        // A list of Names only, does away with the need of EnumModel 
        List<string> MyNames = ((MyEnum[])Enum.GetValues(typeof(MyEnum))).Select(c => c.ToString()).ToList();

        // A list of Values only, does away with the need of EnumModel 
        List<int> myValues = ((MyEnum[])Enum.GetValues(typeof(MyEnum))).Select(c => (int)c).ToList();

        // A dictionnary of <string,int>
        Dictionary<string,int> myDic = ((MyEnum[])Enum.GetValues(typeof(MyEnum))).ToDictionary(k => k.ToString(), v => (int)v);
}

希望能有所帮助

你可以使用下面的泛型方法:

public static List<T> GetItemsList<T>(this int enums) where T : struct, IConvertible
{
    if (!typeof (T).IsEnum)
    {
        throw new Exception("Type given must be an Enum");
    }

    return (from int item in Enum.GetValues(typeof (T))
            where (enums & item) == item
            select (T) Enum.Parse(typeof (T), item.ToString(new CultureInfo("en")))).ToList();
}

/// <summary>
/// Method return a read-only collection of the names of the constants in specified enum
/// </summary>
/// <returns></returns>
public static ReadOnlyCollection<string> GetNames()
{
    return Enum.GetNames(typeof(T)).Cast<string>().ToList().AsReadOnly();   
}

其中T是枚举类型; 添加:

using System.Collections.ObjectModel; 

更简单的方法:

Enum.GetValues(typeof(SomeEnum))
    .Cast<SomeEnum>()
    .Select(v => v.ToString())
    .ToList();

如果你想Enum int作为键和名称作为值，如果你存储的数字到数据库，它是从Enum!

void Main()
{
     ICollection<EnumValueDto> list = EnumValueDto.ConvertEnumToList<SearchDataType>();

     foreach (var element in list)
     {
        Console.WriteLine(string.Format("Key: {0}; Value: {1}", element.Key, element.Value));
     }

     /* OUTPUT:
        Key: 1; Value: Boolean
        Key: 2; Value: DateTime
        Key: 3; Value: Numeric         
     */
}

public class EnumValueDto
{
    public int Key { get; set; }

    public string Value { get; set; }

    public static ICollection<EnumValueDto> ConvertEnumToList<T>() where T : struct, IConvertible
    {
        if (!typeof(T).IsEnum)
        {
            throw new Exception("Type given T must be an Enum");
        }

        var result = Enum.GetValues(typeof(T))
                         .Cast<T>()
                         .Select(x =>  new EnumValueDto { Key = Convert.ToInt32(x), 
                                       Value = x.ToString(new CultureInfo("en")) })
                         .ToList()
                         .AsReadOnly();

        return result;
    }
}

public enum SearchDataType
{
    Boolean = 1,
    DateTime,
    Numeric
}
