Powershell manage set of variables

Question

It should be ok to add all the variables as global inside the function? All the other functions will receive them? I did a short test and it should work. Should I need to add Get-Variable -ValueOnly...?

$ReleaseVersion = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).ReleaseVersion
$Sourceversion = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).Sourceversion
$LinkForVersion = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).LinkForVersion
$VersionNumber = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).VersionNumber
$buildver = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).buildver
$PipelineID = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).PipelineID
$xmlFilePath = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).xmlFilePath
$ReleaseBuildVer = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).ReleaseBuildVer

Set-Variable -Name "ReleaseVersion" -Value $ReleaseVersion -Scope global
Set-Variable -Name "Sourceversion" -Value $Sourceversion -Scope global
Set-Variable -Name "LinkForVersion" -Value $LinkForVersion -Scope global
Set-Variable -Name "VersionNumber" -Value $VersionNumber -Scope global
Set-Variable -Name "buildver" -Value $buildver -Scope global
Set-Variable -Name "PipelineID" -Value $PipelineID -Scope global
Set-Variable -Name "xmlFilePath" -Value $xmlFilePath -Scope global
Set-Variable -Name "ReleaseBuildVer" -Value $ReleaseBuildVer -Scope global

}

I have a script that read from excel collect files according to a column, Before the running I need to define 4 variables, the issue is that I need to run it for several versions. That means that for each run I need to leave active 4 variables and the rest should be in comment (#) and I do it manually (need to add 12 times # There is a smart way to choose all the 4 variables per version?

I will give an example:

Each time only one set is enabled (According to version I want to work on)

The using of those parameters are:

Add-VSTeamWorkItem -ProjectName "Client-Server" -Title "[Side VIP] [$VersionNumber]"

$Versionlocationforpatches = "$Sourceversion\Installer\Patches" 
$Versionlocationforcabs = "$Sourceversion\Installer" 

Add-VSTeamBuild -ProjectName "Client-Server" -BuildDefinitionId $PipelineID

function RenameVerFile ([string] $buildver) 
{
    $DefaultFile = Get-ChildItem $Sourceversion | Where-Object {$_.Name -like "BuildVer.txt"}
    Clear-Content $DefaultFile.FullName -Force 
    $Newcontent = Add-Content $DefaultFile.FullName -Value ($buildver + "." + (Get-Random)) 
    
}

Some of them are using in other places

Now I have something like this and I am very happy but I want to display the user a menu like: For version 8.5.34 choose 1, Without insert manually the number

I hope this will do the job

do {$VersionToUse = $Versions.buildver | Out-Gridview -Title "Choose version" -PassThru } while ($Versions.buildver -notcontains $VersionToUse)

User of the script will now see versions to select and then enter version number to be used. your four variables are then filled with the relevant data.

$SharedDriveFolderPath= "\Test\xxx" # This is just for me to test - you have your own data somewhere
$Versions = @()
$Versions += "VersionNumber;Sourceversion;PipelineID;buildvers;"
$Versions += "8.5.34;$SharedDriveFolderPath\Versions\8.5.34.31;18710;8.5.34.31"
$Versions += "8.5.35;$SharedDriveFolderPath\Versions\8.5.34.35;18713;8.5.34.35"
$Versions = $Versions | ConvertFrom-CSV -Del ";"

do {$VersionToUse = ($Versions | Out-GridView -OutputMode Single -Title "Select version to use").VersionNumber} while (-not $VersionToUse)

$VersionNumber = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).VersionNumber
$Sourceversion = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).Sourceversion
$PipelineID = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).PipelineID
$buildvers = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).buildvers

Take this Code to replace your version lines (the ones you posted here as screenshot example)

Alternative as json if you prefer that:

$SharedDriveFolderPath= "\Test\xxx" # This is just for me to test - you have your own data somewhere
$Versions = @"
[
    {
        "VersionNumber":  "8.5.34",
        "Sourceversion":  "$($SharedDriveFolderPath -replace "\","\")\Versions\8.5.34.31",
        "PipelineID":  "18710",
        "buildvers":  "8.5.34.31"
    },
    {
        "VersionNumber":  "8.5.35",
        "Sourceversion":  "$($SharedDriveFolderPath -replace "\","\")\Versions\8.5.34.35",
        "PipelineID":  "18713",
        "buildvers":  "8.5.34.35"
    }
]
"@ | ConvertFrom-Json

do {$VersionToUse = ($Versions | Out-GridView -OutputMode Single -Title "Select version to use").VersionNumber} while (-not $VersionToUse)

$VersionNumber = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).VersionNumber
$Sourceversion = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).Sourceversion
$PipelineID = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).PipelineID
$buildvers = ($Versions | where {$_.VersionNumber -eq $VersionToUse}).buildvers

Replace the line starting with "do" with the following code to get another way of selection if you don't like the gridview

$i = 0; foreach ($Version in $Versions.VersionNumber) {$i++; "[$i] $Version"; }; $VersionToUse = ($Versions[$(do {"Enter ID of Version to use"; $id = Read-Host} while (-not ($id -le $Versions.count -and $id -gt 0));$id - 1)]).VersionNumber
