Powershell语法，使用zip压缩和全局变量？

Question

I was playing around with the system zip compression, before we always used 7zip and I want to be more agile with all our scripts.

I found this :

$sourceFolder = "C:\folder1"
$destinationZip = "c:\zipped.zip" 
[Reflection.Assembly]::LoadWithPartialName( "System.IO.Compression.FileSystem" )
[System.IO.Compression.ZipFile]::CreateFromDirectory($sourceFolder, $destinationZip)

this works fine! But,

as soon as i create a function out of this and put in global variables i am not able to run the script.

$dest = "C:\_archive\ImportJournals\ImportJournals.zip"

$source = "C:\_archive\ImportJournals\temp\"



function ZipFiles ([string]$destination, [string]$sourcedir )
{
    [Reflection.Assembly]::LoadWithPartialName( "System.IO.Compression.FileSystem" )
    [System.IO.Compression.ZipFile]::CreateFromDirectory($sourcedir, $destination) 
}

ZipFiles ( $dest, $source )

I get an Error : "The path if not of an legal form."

Any Ideas?

调用Powershell函数的语法是：

ZipFiles $dest  $source
