Ouput DisplayVersion Property-CodePudding

I need to output the property of the Variable DisplayVersion which contains the version of the application in the result how do I do that in foreach loop?

$programList = @(
    'SAP'
    'Tanium'
    'Sentinel'
    'DisplayLink'
    'Cisco AnyConnect'
    'Adobe Acrobat Reader'
    'Google'
    'Lotus Notes'
    'Java Runtime'
    'My IT Windows'
    'Qualys'
    'Snow'
    'LogRhythm'

    )

$Regpath = @(
    'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
    'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'
)

$installedPrograms = (Get-ItemProperty $Regpath).where({$_.DisplayName})
$result = foreach($program in $programList)
{
    $check = $installedPrograms.DisplayName -match $program
    if($check)
    {
        foreach($match in $check)
        {
            [pscustomobject]@{
                Program = $program
                Status = 'Found'
                Match = $match
         
            }
        }
        continue
    }

    [pscustomobject]@{
        Program = $program
        Status = 'Not Found'
        Match = $null
        version = $null
    }
}

$result

The output should look something like

Program              Status    Match                                   Version                        
-------              ------    -----                                   -------
SAP                  Found     SAP GUI for Windows 7.60  (Patch 4)     7.60.4

Here is how you can approach the logic for your code, making use of Group-Object -AsHashtable and a maybe a PowerShell class (personal preference here).

$programList = @(
    'SAP'
    'Tanium'
    'Sentinel'
    'DisplayLink'
    'Cisco AnyConnect'
    'Adobe Acrobat Reader'
    'Google'
    'Lotus Notes'
    'Java Runtime'
    'My IT Windows'
    'Qualys'
    'Snow'
    'LogRhythm'
)

$Regpath = @(
    'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*'
    'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'
)

$installedPrograms = (Get-ItemProperty $Regpath).where({ $_.DisplayName }) |
    Group-Object DisplayName -AsHashTable -AsString

class Thing {
    [string] $Program
    [string] $Status = 'Not Found'
    [string] $Match
    [string] $Version

    Thing() { }
    Thing([string] $Program, [string] $DisplayName, [string] $Version) {
        $this.Program = $Program
        $this.Status  = 'Found'
        $this.Match   = $DisplayName
        $this.Version = $Version
    }
}

$result = foreach($program in $programList) {
    if($keys = $installedPrograms.Keys -match [regex]::Escape($program)) {
        foreach($key in $keys) {
            $match = $installedPrograms[$key]
            [Thing]::new($program, $match.DisplayName, $match.DisplayVersion)
        }
        continue
    }
    [Thing]@{ Program = $program }
}

Getting the version just match the displayname back to its corresponding object $installedPrograms.Where({$PSItem.DisplayName -eq $match}).DisplayVersion

[pscustomobject]@{
    Program = $program
    Status = 'Found'
    Match = $match
    Version = $installedPrograms.Where({$PSItem.DisplayName -eq $match}).DisplayVersion   
}
