Passing Array to PowerShell from Windows CMD [duplicate]

Question

I am trying to execute a PowerShell file from Windows CMD using below command.

powershell -NoProfile -NonInteractive -ExecutionPolicy ByPass -File C:\Users\akarri\Desktop\Temp\test1.ps1 -ConfigPathsArray @(1,2,4)

PowerShell code:

Param(
   [Parameter(Mandatory=$True,Position=0)]
   [Object[]] $ConfigPathsArray       
)

function Start-Transform($configsArray) {
    [Object[]] $test = @(1,2,4)
    $test.GetType()

    foreach ($configArray in $test) {
        Write-Output $configArray
    }

    $configsArray.GetType()
    foreach ($configArray in $configsArray) {
        Write-Output $configArray
    }
}

Start-Transform -configsArray $ConfigPathsArray -Verbose

Though I am passing an array from CMD, the count of $configPathsArray is giving me is 1.

It is working fine when I execute the command with -Command option instead of -File but I need your help in executing the same with -File command (Working with TeamCity Enterprise 2019.1.1 (build 66192))

about_powershell.exe:

In contrast, running powershell.exe -File .\test.ps1 -TestParam $env:windir in cmd.exe results in the script receiving the literal string $env:windir because it has no special meaning to the current cmd.exe shell.

This means that @(1,2,4) is passed as literal string to your string, because it won't be expanded to an array. As result $ConfigPathsArray holds one string entry @(1,2,4), therefore Count returns 1.

You could try to use the TeamCity PowerShell Runner as described here.
