获取映射的网络驱动器标签

Question

有办法获得映射的网络驱动器标签吗？我知道通过可以获得多个属性

Get-Object Win32_MappedLogicalDisk 

但它们都不是标签(请不要误解，我不想要名称，即K:，我想要标签，即我的网络驱动器(

Answer 1

您可以使用Com-Shell.Application对象：

$shell  = New-Object -ComObject Shell.Application
(Get-WmiObject -Class Win32_MappedLogicalDisk).DeviceID | 
# or (Get-CimInstance -ClassName Win32_MappedLogicalDisk).DeviceID | 
# or ([System.IO.DriveInfo]::GetDrives() | Where-Object { $_.DriveType -eq 'Network' }).Name |
Select-Object @{Name = 'Drive'; Expression = {$_}},
@{Name = 'Label'; Expression = {$shell.NameSpace("$_").Self.Name.Split("(")[0].Trim()}}
# when done, clear the com object from memory
$null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($shell)
[System.GC]::Collect()
[System.GC]::WaitForPendingFinalizers()

输出：

Drive Label     
----- -----     
X:    MyCode 

---

以上的一些解释：

使用COM对象Shell.Application，您可以深入了解其属性和方法。

.NameSpace  create and return a Folder object for the specified folder
.Self       gets a Read-Only duplicate System.Shell.Folder object
.Name       from that we take the Name property like 'MyCode (X:)'
.Split      this name we split on the opening bracket '(',
[0]         take the first part of the splitted name and 
.Trim()     get rid of any extraneous whitespace characters

另一种方法是进入注册表，但请记住，在映射的网络文件夹被取消映射后，旧的注册表值仍然存在。这就是为什么下面的代码仍然使用两种方法之一来首先查找活动网络映射：

# the registry key to search in
$regKey = 'HKCU:SOFTWAREMicrosoftWindowsCurrentVersionExplorerMountPoints2'
# list the mapped network drives and loop through
# you can also use Get-CimInstance -ClassName Win32_MappedLogicalDisk
Get-WmiObject -Class Win32_MappedLogicalDisk | ForEach-Object {
# create the full registry key by replacing the backslashes in the network path with hash-symbols
$key = Join-Path -Path $regKey -ChildPath ($_.ProviderName -replace '\', '#')
# return an object with the drive name (like 'X:') and the Label the user gave it
[PsCustomObject]@{
Drive = $_.DeviceID  
Label = Get-ItemPropertyValue -Path $key -Name '_LabelFromReg' -ErrorAction SilentlyContinue
}
}

此处也输出：

Drive Label 
----- ----- 
X:    MyCode

Answer 2

我不知道有哪个cmdlet会向您提供该信息。我相信您可以通过使用gci查看注册表来找到它，但您需要清理输出。

get-childitem "HKCU:SoftwareMicrosoftWindowsCurrentVersionExplorerMountPoints2"
