Exchange Web Services API : get mail attachments

问题:

I am using the EWS API 1.2 to access mailboxes on our Exchange Server. This just works fine but there is one thing I cannot achieve : get mail attachments.

Im wrote the following lines :

class Program {     public static void Main(string[] args)     {         try {             ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);             service.Credentials = new WebCredentials("login","password");             service.AutodiscoverUrl("mail@domaine.fr");              ItemView view = new ItemView(10);             FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));              if (findResults != null && findResults.Items != null && findResults.Items.Count > 0)                 foreach (Item item in findResults.Items)                 {                     if (item.Attachments != null)                     {                         IEnumerator<Attachment> e = item.Attachments.GetEnumerator();                     }                        Console.WriteLine(item.Subject);                 }             else                 Console.WriteLine("no items");         }          catch (Exception e) {             Console.WriteLine(e.Message);         }         Console.ReadLine();     } } 

I get all mails in the tested mailbox but IEnumerator<Attachment> e = item.Attachments.GetEnumerator(); seems not to "see" attachments.

Have you got any idea of what I missed ?

Thanks a lot.

I finally managed to get email attachments. I modified my code as below

class Program {     public static void Main(string[] args)     {         try {             ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);             service.Credentials = new WebCredentials("login","pwd");             service.AutodiscoverUrl("mail@domaine.com");              ItemView view = new ItemView(10);             FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));              if (findResults != null && findResults.Items != null && findResults.Items.Count > 0)                 foreach (Item item in findResults.Items)                 {                     EmailMessage message = EmailMessage.Bind(service, item.Id, new PropertySet(BasePropertySet.IdOnly, ItemSchema.Attachments, ItemSchema.HasAttachments));                     foreach (Attachment attachment in message.Attachments)                     {                         if (attachment is FileAttachment)                         {                             FileAttachment fileAttachment = attachment as FileAttachment;                             fileAttachment.Load();                             Console.WriteLine("Attachment name: " + fileAttachment.Name);                         }                     }                     Console.WriteLine(item.Subject);                 }             else                 Console.WriteLine("no items");         } catch (Exception e) {              Console.WriteLine(e.Message);         }         Console.ReadLine();     } }
