PowerShell PSCX 读取存档：无法绑定参数...问题

我遇到了一个问题，我似乎无法使用通过 PowerShell 社区扩展 (v2.0.3782.38614) 提供的 Read-Archive cmdlet 来解决这个问题。

这是一个用于展示我遇到的问题的缩减示例：

$mainPath = "p:\temp"
$dest = Join-Path $mainPath "ps\CenCodes.zip"
Read-Archive -Path $dest -Format zip

运行上面的代码会产生以下错误：

Read-Archive : Cannot bind parameter 'Path'. Cannot convert the "p:\temp\ps\CenCodes.zip" value of type "System.String" to type "Pscx.IO.PscxPathInfo".
At line:3 char:19
+ Read-Archive -Path <<<<  $dest -Format zip
    + CategoryInfo          : InvalidArgument: (:) [Read-Archive], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Pscx.Commands.IO.Compression.ReadArchiveCommand

如果我不使用 Join-Path 来构建传递给 Read-Archive 的路径，它就可以工作，如本示例所示：

$mainPath = "p:\temp"
$path = $mainPath + "\ps\CenCodes.zip"
Read-Archive -Path $path -Format zip

上面的输出：

    ZIP Folder: CenCodes.zip#\

Index          LastWriteTime         Size    Ratio Name                                                                                       -----          -------------         ----    ----- ----
0         6/17/2010  2:03 AM      3009106  24.53 % CenCodes.xls

更令人困惑的是，如果我比较上面两个读取存档示例中作为 Path 参数传递的两个变量，它们看起来相同：

这...

Write-Host "dest=$dest"
Write-Host "path=$path"
Write-Host ("path -eq dest is " + ($dest -eq $path).ToString())

输出...

dest=p:\temp\ps\CenCodes.zip
path=p:\temp\ps\CenCodes.zip
path -eq dest is True

任何人都对为什么第一个示例有任何想法抱怨但第二个工作正常吗？

原文

I'm running across a problem I can't seem to wrap my head around using the Read-Archive cmdlet available via PowerShell Community Extensions (v2.0.3782.38614).

Here is a cut down sample used to exhibit the problem I'm running into:

$mainPath = "p:\temp"
$dest = Join-Path $mainPath "ps\CenCodes.zip"
Read-Archive -Path $dest -Format zip

Running the above produces the following error:

Read-Archive : Cannot bind parameter 'Path'. Cannot convert the "p:\temp\ps\CenCodes.zip" value of type "System.String" to type "Pscx.IO.PscxPathInfo".
At line:3 char:19
+ Read-Archive -Path <<<<  $dest -Format zip
    + CategoryInfo          : InvalidArgument: (:) [Read-Archive], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Pscx.Commands.IO.Compression.ReadArchiveCommand

If I do not use Join-Path to build the path passed to Read-Archive it works, as in this example:

$mainPath = "p:\temp"
$path = $mainPath + "\ps\CenCodes.zip"
Read-Archive -Path $path -Format zip

Output from above:

    ZIP Folder: CenCodes.zip#\

Index          LastWriteTime         Size    Ratio Name                                                                                       -----          -------------         ----    ----- ----
0         6/17/2010  2:03 AM      3009106  24.53 % CenCodes.xls

Even more confusing is if I compare the two variables passed as the Path argument in the two Read-Archive samples above, they seem identical:

This...

Write-Host "dest=$dest"
Write-Host "path=$path"
Write-Host ("path -eq dest is " + ($dest -eq $path).ToString())

Outputs...

dest=p:\temp\ps\CenCodes.zip
path=p:\temp\ps\CenCodes.zip
path -eq dest is True

Anyone have any ideas as to why the first sample gripes but the second one works fine?

我在 PSCX CodePlex 主页上的问题跟踪器中创建了一个项目。显然这是 PscxPathInfo 当前的已知问题。（请参阅 PSCX 问题跟踪器中的项目 #28023）。

解决方法是这样做：

Get-Item $dest | Read-Archive

归功于 CodePlex 上的 r_keith_hill 的特定解决方法。

I created an item in the issue tracker on the CodePlex home of PSCX. Apparently this is a current known issue with PscxPathInfo. (See item #28023 in the PSCX Issue Tracker).

A work around is to do this:
