Answer 1

partial class Program
{
    static void Main()
    {
        PropertyInfo[] peroperties = typeof(A).GetProperties(BindingFlags.Public | BindingFlags.Instance);
        foreach (PropertyInfo property in peroperties)
        {
            object[] objs = property.GetCustomAttributes(typeof(DescriptionAttribute), true);
            if (objs.Length > 0)
            {
              Console.WriteLine("{0}: {1}", property.Name, ((DescriptionAttribute)objs[0]).Description);
            }
        }
        Console.ReadKey();
    }
}class A
{
    [Description("X")]
    public string X
    {
        get { return null; }
    }
    [Description("Y")]
    public string Y
    {
        get { return null; }
    }
}

Answer 2

反射，一般要获取元数据都得通过反射partial class Program
{
  static void Main()
  {
  PropertyInfo[] peroperties = typeof(A).GetProperties(BindingFlags.Public | BindingFlags.Instance);
  foreach (PropertyInfo property in peroperties)
  {
  object[] objs = property.GetCustomAttributes(typeof(DescriptionAttribute), true);
  if (objs.Length > 0)
  {
  Console.WriteLine("{0}: {1}", property.Name, ((DescriptionAttribute)objs[0]).Description);
  }
  }
  Console.ReadKey();
  }
}class A
{
  [Description("X")]
  public string X
  {
  get { return null; }
  }
  [Description("Y")]
  public string Y
  {
  get { return null; }
  }
}
