试试Convert-Pathcmdlet：

PS> Convert-Path Microsoft.PowerShell.Core\FileSystem::C:\windows\system32
C:\windows\system32

我不确定为什么该FullName属性将 powershell 提供程序添加到名称之前，这通常是您在该PsPath属性中得到的。

无论如何，您尝试剥离它失败的原因是因为您在需要整数索引时将 String 传递给SubString成员函数。要获取路径开始的索引，请使用IndexOf成员函数：

$justThePath = $_.FullName.SubString($_.FullName.IndexOf($Path))
