Question

我有一个调用WinSCP .NET程序集的脚本。该脚本从FTP目录下载最新文件，并根据文件扩展名+ .txt（2245.xml - ＆gt; xml.txt）为其命名。

我需要创建一个过滤器，仅下载名为tn*或nc1的文件扩展名。任何人都可以指出我正确的方向：

$session = New-Object WinSCP.Session

# Connect
$session.Open($sessionOptions)

# Get list of files in the directory
$directoryInfo = $session.ListDirectory($remotePath)

# Select the most recent file
$latest = $directoryInfo.Files |
    Where-Object { -Not $_.IsDirectory} | 
    Group-Object { [System.IO.Path]::GetExtension($_.Name) } | 
    ForEach-Object{ 
        $_.Group | Sort-Object LastWriteTime -Descending | Select -First 1
    }

$extension = [System.IO.Path]::GetExtension($latest.Name)
"GetExtension('{0}') returns '{1}'" -f $fileName, $extension

if ($latest -eq $Null)
{
    Write-Host "No file found"
    exit 1
}

# Download

$latest | ForEach-Object {
    $extension = ([System.IO.Path]::GetExtension($_.Name)).Trim(".")
    $session.GetFiles($session.EscapeFileMask($remotePath + $_.Name), "$localPath\$extension.txt" ).Check()
}

我尝试在目录排序中添加过滤器，但这不起作用：

    Where-Object { -Not $_.IsDirectory -or [System.IO.Path]::GetExtension($_.Name) -like "tn*" -or [System.IO.Path]::GetExtension($_.Name) -eq "nc1"} |

谢谢！

您的代码几乎是正确的。只是需要：

-and具有“not directory”条件的扩展条件。或者使用两个单独的Where-Object条款，如下所示。
GetExtension结果包含点。

$latest = $directoryInfo.Files |
    Where-Object { -Not $_.IsDirectory} | 
    Where-Object {
        [System.IO.Path]::GetExtension($_.Name) -eq ".nc1" -or
        [System.IO.Path]::GetExtension($_.Name) -like ".tn*"
    } |
    Group-Object { [System.IO.Path]::GetExtension($_.Name) } | 
    ForEach-Object { 
        $_.Group | Sort-Object LastWriteTime -Descending | Select -First 1
    }

我需要修改我的WinSCP脚本以仅下载特定文件扩展名的文件
