Unfortunately that’s not possible. Enums can only have a basic underlying type (int, uint, short, etc.). If you want to associate the enum values with additional data, apply attributes to the values (such as the DescriptionAttribute).

public static class EnumExtensions
{
    public static TAttribute GetAttribute<TAttribute>(this Enum value)
        where TAttribute : Attribute
    {
        var type = value.GetType();
        var name = Enum.GetName(type, value);
        return type.GetField(name)
            .GetCustomAttributes(false)
            .OfType<TAttribute>()
            .SingleOrDefault();
    }

    public static String GetDescription(this Enum value)
    {
        var description = GetAttribute<DescriptionAttribute>(value);
        return description != null ? description.Description : null;
    }
}

enum MyEnum
{
    [Description("abc")] Name1,
    [Description("xyz")] Name2,
}

var value = MyEnum.Name1;
if (value.GetDescription() == "abc")
{
    // do stuff...
}
