How to output from a Powershell hashtable to a output file - powershell

Question

I am trying to get the .NetFramwork version from all the windows servers. I am using powershell script. I can get the output displayed but unable to get the output from the hashtable to a output file. Also how would I get rid of the "..." from VersionDetails : {1.0.3705, 1.1.4322, 2.0.50727, 3.0...} and show the full content.
Any help will be greatly appreciated
here is the code I am using:
$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
}

Based on the answer of link there is a "simpler" (and faster) solution to fetch the versions.
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
If you want to get the versions of different remote machines you can use PowerShell remoting. Be aware that you've to enable PS remoting .If your OS version is WIN10/WIN2012R2 it is enabled per default. If you're using an older OS you've to call Enable-PSRemoting on the remote machine. See this link for details.
Example:
$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
Hope that helps.
