Exception Powershell WebClient下载文件异常路径中包含非法字符

我试图从FTP站点下载zip文件，通过检索目录列表来查找文件名

下载部分：

$folderPath='ftp://11.111.11.11/'
$target = "C:\Scripts\ps\ftpdl\"

Foreach ($file in ($array | where {$_ -like "data.zip"})) {

$Source = $folderPath+$file
$Path = $target+$file

#$Source = "ftp://11.111.11.11/data.zip"
#$Path = "C:\Scripts\ps\ftpdl\data.zip"

$source
Write-Verbose -Message $Source -verbose
$path
Write-Verbose -message $Path -verbose

$U = "User"
$P = "Pass"
$WebClient2 = New-Object System.Net.WebClient
$WebClient2.Credentials = New-Object System.Net.Networkcredential($U, $P)
$WebClient2.DownloadFile( $source, $path )  
}

如果我使用注释掉的字符串并正确定义它下载的字符串。但如果我按图所示运行它，我会收到路径中非法字符的异常错误。有趣的是，写得冗长和不写之间有区别

运行时的输出，如图所示：

ftp://11.111.11.11/data.zip
data.zip
C:\Scripts\ps\ftpdl\data.zip
data.zip
Exception calling "DownloadFile" with "2" .........

使用硬编码路径和源运行时的输出

ftp://11.111.11.11/data.zip
VERBOSE: ftp://11.111.11.11/data.zip
C:\Scripts\ps\ftpdl\data.zip
VERBOSE: C:\Scripts\ps\ftpdl\data.zip

文件下载得很好。

当然，一旦我发布了问题，我就明白了。My$数组包含

`n

和

`r

字符。我需要找到并替换它们

$array=$array -replace "`n",""
$array=$array -replace "`r",""
