Question

我有一个用于压缩文件的powershell脚本，我遇到了一些问题。我的脚本的简化版本是：

function MyFunction([__ComObject] $zipFile)
{
   if(test-path($zipFile.Self.Path))
   {
      "Zip path found in MyFunction: " + $zipFile.Self.Path
   }
   else
   {
     "Zip path not found in MyFunction: " + $zipFile.Self.Path
   }
   # Check path directly
   if(test-path("C:\zips\july2013.zip"))
   {
      "Direct zip path found in MyFunction: " + $zipFile.Self.Path
   }
   else
   {
     "Direct zip path not found in MyFunction: " + $zipFile.Self.Path
   }
}

$zipfilepath = "C:\zips\july2013.zip"

if(-not (test-path($zipfilepath)))
{
   set-content $zipfilepath ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
   (dir $zipfilepath).IsReadOnly = $false               
}

$shellApplication = new-object -com shell.application
$zipPackage = $shellApplication.NameSpace($zipfilepath)

if( (test-path($zipPackage.Self.Path)))
{
   "Zip exists: " + $zipPackage.Self.Path
}
else
{
    "Zip does not exist: " + $zipPackage.Self.Path
}
MyFunction $zipPackage

如果在我运行脚本之前存在C：\ zips \ july2013.zip，或者我通过打开powershell来调试我得到（正如我所期望的那样）：

Zip exists: C:\zips\july2013.zip
Zip path found in MyFunction: C:\zips\july2013.zip
Direct zip path found in MyFunction: C:\zips\july2013.zip

但是如果文件不存在C：\ zips \ july2013.zip并且我在没有打开powershell的情况下运行它（即右键单击“使用powershell运行”）我得到：

Zip exists: C:\zips\july2013.zip
Zip path not found in MyFunction: C:\zips\july2013.zip
Direct zip path not found in MyFunction: C:\zips\july2013.zip

我是PowerShell的新手，任何想法是什么？

Powershell - 外部函数找不到新创建的zip文件路径
