độc đáo đọc outlook tài sản mailitem

Question

Tôi đang viết một plugin cho outlook 2007 và tôi muốn đọc một tài sản của một MailItem.

Đặc biệt tôi muốn biết tất cả các loại nội dung đính kèm của tôi. Bây giờ cách tôi làm điều này bây giờ là một cái gì đó như thế này:

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"); 
} 

Nhưng tôi sẽ chỉ gọi một cái gì đó như thế nào.

t.PropertyAccessor.GetProperty(PR_ATTACH_MIME_TAG); 

Tôi không thể có tùy chọn sau này để làm việc, tuy nhiên thuộc tính được đề cập theo cách đó trong tài liệu msdn. (http://msdn.microsoft.com/en-us/library/ms879575.aspx). Có ai biết làm thế nào để độc đáo lấy tài sản mà không sử dụng chuỗi nhưng thay vì liên tục?
