PowerShell 测试路径在测试网络共享时返回 False [英] PowerShell Test-Path returns False when testing a network share

问题描述

用户具有读取共享的适当权限，并且共享映射正确.此问题似乎仅在 PowerShell v2.0 中发生.

The user has appropriate permissions to read the share, and the share maps properly. This issue seems to happen only in PowerShell v2.0.

如果我删除所有映射的驱动器，重新映射一个驱动器，然后运行测试路径:

If I remove all mapped drives, remap one drive, and run Test-Path:

net use /delete * /y
net use G: \\somefileserver\share
Test-Path G:\

Test-Path 返回 False，即使驱动器已明确映射，并且我可以通过 Windows 资源管理器访问它.

Test-Path returns False, even though the drive is clearly mapped, and I can access it through Windows Explorer.

如果我关闭 PowerShell 会话并打开一个新会话，Test-Path 将返回 True，它应该如此.关于(A)的任何想法:什么可能导致这种情况，以及如何使其正常工作?或 (B): 除了 Test-Path 之外，还有其他方法可以测试网络驱动器的存在吗?我正在尝试编写一个登录脚本来映射用户的网络驱动器，这种行为让我发疯.

If I close the PowerShell session, and open a new session, Test-Path returns True, as it should. Any ideas on, (A): what could be causing this, and how do I make it work properly? or (B): Is there another way to test for the existence of a network drive besides Test-Path? I am attempting to write a logon script to map user's network drives and this behavior is driving me insane.

推荐答案

如果 Test-Path cmdlet 确实有问题，那么我建议使用 Exists() System.IO.Directory .NET 类上的方法.

If the Test-Path cmdlet is truly buggy, then I'd suggest using the Exists() method on the System.IO.Directory .NET class.

[System.IO.Directory]::Exists('G:\'); # This returns $true for me
