我使用Powershell從ftp站點下載新文件

Question

我的腳本用一個ftp站點的數據下載一個硬編碼文件名，但我需要它下載最新的文件和（可能是上次下載的時間戳）。我剛開始使用PowerShell，並尋找線索，使我的腳本更復雜，但似乎無法獲得大部分IVE發現的代碼。你能給我一些方向嗎？這是我當前的代碼：

# Create FTP Connection 
$FTPRequest = [System.Net.FtpWebRequest]::Create("ftp://ftp.sitepath/newestfile.txt") 
$FTPRequest.Credentials = New-Object System.Net.NetworkCredential("username", "pw") 
$FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile 

$FTPRequest.UsePassive = $false 
$FTPRequest.UseBinary = $true 
$FTPRequest.KeepAlive = $false 
$folderName = (Get-Date).tostring("dd-MM-yyyy-hh-mm-ss")    
New-Item -itemType Directory -Path \\server\directory\ -Name $FolderName 
$targetfile = New-Object 
IO.FileStream "\\server\directory\$FolderName\newestfilename.txt"),  [IO.FileMode]::Create) 
# Get FTP File 
$FTPResponse = $FTPRequest.GetResponse() 
$ResponseStream = $FTPResponse.GetResponseStream() 
$FTPReader = New-Object -typename System.IO.StreamReader -ArgumentList $ResponseStream 
[byte[]]$readbuffer = New-Object byte[] 1024 

#loop through the download stream and send the data to the target file 
do{ 
    $readlength = $ResponseStream.Read($readbuffer,0,1024) 
    $targetfile.Write($readbuffer,0,$readlength) 
} 
while ($readlength -ne 0) 
$FTPReader.Close() 

$FTPReader.Close() 

Thank you for your help.

使用PowerShell FTP模塊（http://gallery.technet.microsoft.com/scriptcenter/PowerShell-FTP-Client-db6fe0cb） - 然後你可以專注於自己的業務邏輯，而不是讓「的FTP部分」的工作。
