为什么我无法检索使用互操作的Outlook中的所有MailItems？ [英] Why can't I retrieve ALL MailItems using interop outlook?

问题描述

我试图用Microsoft.Office.Interop.Outlook检索我的Outlook收件箱的邮件。这是我的代码：

I'm trying to use Microsoft.Office.Interop.Outlook to retrieve emails from my Outlook inbox. This is my code:

  Application app = new Application();
  NameSpace ns = app.Session;
  MAPIFolder inbox = ns.GetDefaultFolder(OlDefaultFolders.olFolderInbox);
  Items items = inbox.Items;
  foreach (Microsoft.Office.Interop.Outlook.MailItem mail in items)
        {
            if (mail as MailItem != null)
            {
                Console.WriteLine(mail.Subject.ToString());
                Console.WriteLine(mail.Body.ToString());
                Console.ReadKey();
             }
        }

当我这样做，它的工作原理 - 样的。这只能说明一个电子邮件。应该有三个。它显示的电子邮件是最古老的一个在那里......我为什么不能够得到所有三个？是否有除的MailItem一些其他类型的邮件，这将是我的收件箱？

When I do this, it works--sort of. It only shows one email. There should be three. The email it's showing is the oldest one in there... why wouldn't I be able to get all three? Is there some other type of mail besides MailItem that would be in my inbox?

推荐答案

我有同样的确切问题 - 我的解决方法是只创建一个列表<的MailItem> 和环路通过。确保电子邮件不是在子文件夹虽然，否则他们将不会被发现。

I had this same exact problem - My workaround was just to create a List<MailItem> and loop through that. Make sure the emails aren't in subfolders though, otherwise they won't be found.

Outlook.Application app = new Outlook.Application();
Outlook.NameSpace outlookNs = app.GetNamespace("MAPI");
Outlook.MAPIFolder emailFolder = outlookNs.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);

List<MailItem> ReceivedEmail = new List<MailItem>(); 
foreach (Outlook.MailItem mail in emailFolder.Items)               
        { ReceivedEmail.Add(mail); }

foreach (MailItem mail in ReceivedEmail)
{
    //do stuff
}
