Outlook 2007 用のプラグインを作成していますが、MailItem のプロパティを読み取りたいと考えています。

特に、添付ファイルのすべてのコンテンツ タイプを知りたいです。今私がこれを行う方法は次のようなものです：

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");
}

しかし、私はむしろ次のようなものを呼びたいです。

t.PropertyAccessor.GetProperty(PR_ATTACH_MIME_TAG);

後でそのオプションを機能させることはできませんが、プロパティはmsdnのドキュメントでそのように言及されています。(http://msdn.microsoft.com/en-us/library/ms879575.aspx)。文字列ではなく定数を使用せずにプロパティをうまく取得する方法を知っている人はいますか?
