proprietà di maillooking outlook leggibile

Question

Sto scrivendo un plugin per Outlook 2007 e vorrei leggere una proprietà di un MailItem.

In particolare mi piacerebbe conoscere tutti i tipi di contenuto dei miei allegati. Ora il mio modo di fare questo ora è qualcosa di simile:

Outlook.MailItem item = OutlookItem as Outlook.MailItem; 
Outlook.Attachments itt = item.Attachments; 

foreach (Outlook.Attachment t in item.Attachments) 
{ 
textBox1.Text += t.PropertyAccessor.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x370E001F"); 
} 

Ma sarebbe molto meglio basta chiamare qualcosa di simile.

t.PropertyAccessor.GetProperty(PR_ATTACH_MIME_TAG); 

non riesco a ottenere che opzione più tardi a lavorare tu, ma la proprietà è menzionato in questo modo nella documentazione MSDN. (Http://msdn.microsoft.com/en-us/library/ms879575.aspx). Qualcuno sa come recuperare le proprietà senza usare la stringa ma la costante?
