查找使用EWS收件箱文件夹的所有子文件夹 [英] Find all subfolders of the Inbox folder using EWS

问题描述

我有以下的收件箱文件夹结构：

I have the following Inbox folder structure:

Inbox
--ABC
----ABC 2
----ABC 3
--XYZ
----XYZ 2
--123
----123 A
----123 B
----123 C

我使用外汇Web服务和下面的代码找到收件箱文件夹的子文件夹：

I am using Exchange Web Services and the following code to find the child folders of the Inbox folder:

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);

service.AutodiscoverUrl("[e-mail]");
Mailbox mb = new Mailbox("[e-mail]");

FindFoldersResults findResults = service.FindFolders(
    WellKnownFolderName.Inbox,
    new FolderView(int.MaxValue));

foreach (Folder folder in findResults.Folders)
{
    Console.WriteLine(folder.DisplayName);
}

这部分工作，因为它返回的ABC，XYZ，和123文件夹;不幸的是，它不会返回内的每个这些文件夹的文件夹（ABC 2，ABC 3，XYZ 2，123 A，123 B，123 C）。

This partly works because it returns the ABC, XYZ, and 123 folders; unfortunately, it does not return the folders inside each of those folders (ABC 2, ABC 3, XYZ 2, 123 A, 123 B, 123 C).

此外，它可能是一个文件夹可以有它里面的子文件夹的多个级别。

Also, it is possible that a folder could have more than one level of subfolders inside it.

我怎么可以这样写代码，以便将返回所有子文件夹，无论有多深嵌套他们可能是？

How can I write this code so that it will return all subfolders regardless of how deeply nested they may be?

推荐答案

您可以告诉EWS搜索文件夹时做深跨度。您可以使用 FolderView.Traversal 财产。然后，您的代码将改为类似下面的内容：

You can tell EWS to do a deep traversal when searching the folders. You can do this using the FolderView.Traversal property. Your code would then be changed to something similar to the following:

FindFoldersResults findResults = service.FindFolders(
    WellKnownFolderName.Inbox,
    new FolderView(int.MaxValue) { Traversal = FolderTraversal.Deep });
