如何从 Powershell 哈希表输出到输出文件

Question

我正在尝试从所有 Windows 服务器获取 .NetFramwork 版本。我正在使用 powershell 脚本。我可以显示输出，但无法将哈希表中的输出获取到输出文件。另外，我将如何摆脱 VersionDetails 中的“...”：{1.0.3705, 1.1.4322, 2.0.50727, 3.0...} 并显示完整内容。

任何帮助将不胜感激

这是我正在使用的代码：

$username = "username"
$password = "Password"
$secstr = New-Object -TypeName System.Security.SecureString
$password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr
$query = "select name from win32_directory where name like 'c:\\windows\\microsoft.net\\framework\\v%'"

$ComputerNames = Get-Content "d:\Scripts\serverList.txt"

foreach ($ComputerName in $ComputerNames)
   {
write-host "ComputerName = $ComputerName"
$ComputerName | ForEach-Object {
$res = Get-WmiObject -query $query -Credential $cred -ComputerName $ComputerName | ForEach-Object {
Split-Path $_.name -Leaf } | # returns directories
    Where-Object { $_ -like 'v*' } | # only include those that start with v
        ForEach-Object { [system.version]( $_ -replace "^v" ) }     
# remove "v" from the string and convert to version object

# Create hashtable with computername and version details
$prop = @{
    ComputerName = $ComputerName
    #V1_Present = &{ if ( $res | Where-Object { $_.Major -eq 1 -and $_.Minor -eq 0 } ) { $true } }
    #V1_1Present = &{ if ( $res | Where-Object { $_.Major -eq 1 -and $_.Minor -eq 1 } ) { $true } }
    V2_Present = &{ if ( $res | Where-Object { $_.Major -eq 2 -and $_.Minor -eq 0 } ) { $true } }
        V3_Present = &{ if ( $res | Where-Object { $_.Major -eq 3 -and $_.Minor -eq 0 } ) { $true } }
    V3_5Present = &{ if ( $res | Where-Object { $_.Major -eq 3 -and $_.Minor -eq 5 } ) { $true } }
    V4_Present = &{ if ( $res | Where-Object { $_.Major -eq 4 -and $_.Minor -eq 0 } ) { $true } }
    VersionDetails  = $res
}
# Create and output PSobject using hashtable
New-Object PSObject -Property $prop
}

根据link 的回答，有一个“更简单”（更快）的解决方案来获取版本。

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse | Get-ItemProperty -name Version,Release -ErrorAction Ignore | Where { $_.PSChildName -match '^(?!S)\p{L}'} | Select PSChildName, Version, Release

如果您想获取不同远程计算机的版本，您可以使用 PowerShell 远程处理。请注意，您必须启用 PS 远程处理。如果您的操作系统版本是 WIN10/WIN2012R2，则默认启用它。如果您使用的是较旧的操作系统，您必须在远程计算机上调用Enable-PSRemoting。有关详细信息，请参阅此link。

例子：

$result = Invoke-Command -ComputerName computer1.domain, computer1.domain -Credential (Get-Credential ) -ScriptBlock {
    Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse | Get-ItemProperty -name Version,Release -ErrorAction Ignore | Where { $_.PSChildName -match '^(?!S)\p{L}'} | Select PSChildName, Version, Release
}

$hash = $result | group PSComputerName -AsHashTable # Group the .Net versions by computername

$hash.'computer1.domain'            # Print all  .Net version of computer1
$hash.'computer1.domain'.Version    # Only print the version

希望对您有所帮助。
