使用 Mailkit 和 Powershell 在 Imap 文件夹中搜索未读电子邮件

Question

我想使用 Mailkit 和 Powershell 在我的所有 Imap 文件夹中搜索未读电子邮件。但我什至无法列出所有文件夹。代码如下：

$cl = New-Object MailKit.Net.Imap.ImapClient([mailkit.protocollogger]::new([console]::OpenStandardOutput()))

#connect
$cl.Connect($mailserver, $port)
$cl.Authenticate($username,$password)   
$cl.GetFolders($Cl.PersonalNamespaces[0])

结果始终是：“文件夹当前未打开。”但我想我需要先阅读文件夹对象才能打开它们？ 有趣的是，protocollogger 很好地列出了我所有的文件夹：

... long list of all my folders ...

S: A00000005 OK LIST completed

但我只是收到错误消息：

您的日志显示您粘贴的代码 sn-p 工作正常。

您没有从您粘贴的任何代码中获得异常。

您在粘贴的代码之后从代码中获取了异常。

要修复您提到的异常，您需要在您尝试搜索的文件夹上调用Open(FolderAccess.ReadWrite) 方法，然后才能调用Search()。
