一般信息
我还在学习C#.为了帮助自己,我正在尝试创建一个程序,它将自动将我的所有本地项目与我的FTP服务器上的文件夹同步.这样,无论我是在学校还是在家,我总是可以使用相同的项目.

我知道像Dropbox这样的程序已经为我做了这个,但我想创造类似的东西,我自己会教我很多东西.

问题
我迈向目标的第一步是从我的FTP服务器下载所有文件,子目录和子文件.我已经设法从下面的代码下载目录中的所有文件.但是,我的代码只列出了主目录中的文件夹名称和文件.子文件夹和子文件永远不会返回,也永远不会下载.除此之外,服务器返回550错误,因为我正在尝试下载文件夹,就像它们是文件一样.我已经在这上面了4个多小时了,但我找不到任何关于如何解决这些问题并让它发挥作用的事情.因此,我希望你们能帮助我:)

I have to write a script which accesses an FTP server, and then deletes all *.zip files which are older than X days.

As clarification: The script can't run on the FTP server.

This is what I have so far:

$ftpServer = "RandomFTPServer"
$ftpUser = "Username"
$ftpPassword = Read-Host "Password" -AsSecureString

$credentials = New-ObjectSystem.Net.NetworkCredential($ftpUser, $ftpPassword)

function Get-FtpRequest($ftpPath) {
    $ftpRequest = [System.Net.FtpWebRequest]::Create("$ftpServer/$ftpPath")
    $ftpRequest.Credentials = $credentials
    $ftpRequest.UseBinary = $true 
    $ftpRequest.KeepAlive = $true
    $ftpRequest.UsePassive = $true
    return $ftpRequest
}

Any tips on what …
