item.HasAttachments为true，但集合中没有附件 [英] item.HasAttachments is true but no attachments in collection

问题描述

我需要检索&从许多邮件项目中复制附件.问题是，即使属性HasAttachment为true，每个邮件项目的集合也为空.

I need to retrieve & copy attached files from a number of mail items. Problem is each mail item's collection is empty, even though the property HasAttachment is true.

检索邮件项目后，是否需要以某种方式加载每个邮件项目的附件链接?

Do I need to load each mail item's attachment colloection somehow after the mail item is retrieved?

以下代码吐出异常索引超出范围":

The following code spits out the exception "index is out of range.":

FindItemsResults<Item> findResults = service.FindItems(
                WellKnownFolderName.Inbox,
                new ItemView(1));

foreach (Item item in findResults.Items)
{
    if (item.HasAttachments && item.Attachments[0] is FileAttachment)
    {
         //Do stuff
    }
}

推荐答案

继续解决方案； item.Load().我认为这是合乎逻辑的，因为在不需要时，轻量级应用程序可能对收集大量附件不感兴趣.

Fell upon the solution; item.Load(). I guess it's logical since a light application might not be interested in collecting heavy attachments when not needed.
