.net &引用；CreateFromDirectory"；加上；4“；论点：“；该路径不是合法形式。”；

我正在尝试将一个月的文件夹压缩到一个文件中。例如，201501适用于jan的所有文件夹，我需要压缩到名为somename-2015-jan.zip的文件。所有其他逻辑仅在显示上述错误的zipplig部分工作。我有powershell v3和Net4.54，当我调用System.IO.Compression.ZipFile]时出现了一些问题：CreateFromDirectory来压缩文件

                  $year = 2015  
              $base = "D:\Archive\"


              $folder = Get-Content "D:\Archive\MasterFolder.txt"
                          #write-host $folder.count total lines read from file
                          foreach ($Fname in $folder)
                          {

                  $yearmonth = Get-Content "D:\Archive\duration.txt"
                                      write-host $yearmonth.count total lines read from file
                                      foreach ($date in $yearmonth)
                  {


            $source = "$base$Fname\$date*"


            #[string]$text = "$date"    

            $string = $date
            #201501
            $mmd = $string.Substring(4,2)
                Write-host "fffcmd $mmd"


            if ($mmd -gt 12) {
                "$mmd is bigger than 12 Which is not valid,Please Correct The file name durations.txt and run the command again"
                 break
                        } 

Else {

write-host " This is Source Folder Name !!!!!!!!!!!!!!!!!!!!$source"
switch($mmd) 
    { 
    "01" {$mm = "jan"
        write-host "New mm is $mm"
}

    "02" {$mm = "Feb"
        write-host "New mm is $mm"
}

   "03" {$mm = "Mar"
        write-host "New mm is $mm"
}
   "04" {$mm = "Apr"
        write-host "New mm is $mm"
}
   "05" {$mm = "May"
        write-host "New mm is $mm"
}
   "06" {$mm = "Jun"
        write-host "New mm is $mm"
}
   "07" {$mm = "Jul"
        write-host "New mm is $mm"
}
   "08" {$mm = "Aug"
        write-host "New mm is $mm"
}
   "09" {$mm = "Sep"
        write-host "New mm is $mm"

        write-host "New mm is $mm"

   "11" {$mm = "Now"
        write-host "New mm is $mm"
}
   "12" {$mm = "Dec"
        write-host "New mm is $mm"
}
    default
    {
      Write-host "The Month Duration $mmd  is not valid";continue
   }
 }
            $destination = "$base$Fname\$Fname-$year-$mm.zip"
            write-host " Destination $destination"
            Add-Type -assembly "system.io.compression.filesystem"


function ZipFiles( $zipfilename, $sourcedir )   
{
[Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem")
 $compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal
[System.IO.Compression.ZipFile]::CreateFromDirectory($sourcedir,
    $zipfilename, $compressionLevel, $false)
}
ZipFiles "$destination", "$source"

                  }

            start-sleep -s 1
                          }

}

看起来提供参数的方式不正确，或者源代码中的通配符不正确。

CreateFromDirectory

不允许使用通配符。改用

Get ChildItem

排队后

$source = "$base$Fname\$date*"

将匹配的文件传递到

foreach

循环：

$files = (Get-ChildItem "$base$Fname\$date*")

foreach ($file in $files) {
    # ...
    # Continue with the rest of your code, starting at the line "$string = $date"
    # ...
    ZipFiles $destination, $file.FullName
}

其他一些建议：

将

ZipFiles

函数定义移到

foreach

循环之外，它不需要在每次循环运行时重新定义

将加载/导入

System.IO.Compression.FileSystem

移动到

foreach

es之外

删除整个

switch

语句，并将其替换为以下内容：

$mm=[CultureInfo]：：CurrentCulture.DateTimeFormat.Get缩写月名（$mmd）
