}
static string GetDescription<T>(this T value)
{
var memInfo = value.GetType().GetMember(value.ToString());
var attributes = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false).Cast<DescriptionAttribute>();
if (attributes.Any())
return attributes.First().Description;
return string.Empty;
}
static void Main()
{
foreach (var s in Enum.GetValues(typeof(Orientation)))
{
Console.WriteLine("值：{0}\t\t说明：{1}", s.ToString(), s.GetDescription());
}

Console.Read();
