If / Else Помощь в Powershell

Запуск оператора IF / Else и, если "false", я хочу, чтобы он запустил поиск текущего драйвера NVIDIA и сказал мне текущую версию, затем остановил скрипт. Пробовал пару разных вещей безрезультатно. В настоящее время он продолжает выполнение сценария и запускает «Get-WmiObject» в следующем порядке. 


Function Namespace_Check
{    Write-Host "Checking available namepace" -ForegroundColor Green

     if ((Get-CimInstance -namespace "root\cimv2" -ClassName __NAMESPACE).Name -match 'NV'){return}

     else { return (Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion | where {$_.devicename -like "*nvidia*"})}

     Write-Host "If Stopped, install latest NVIDIA driver from SWE"
     Write-Host "Complete" -ForegroundColor Green   

}

Вот весь сценарий, если в логике должны быть другие изменения 


Function Namespace_Check
{    Write-Host "Checking available namepace" -ForegroundColor Green
     Write-Host "Complete" -ForegroundColor Green

     if ((Get-CimInstance -namespace "root\cimv2" -ClassName __NAMESPACE).Name -match 'NV'){return}

     else { 

     exit (Get-WmiObject Win32_PnPSignedDriver| select devicename, driverversion | where {$_.devicename -like "*nvidia*"})

Если вы хотите, чтобы скрипт полностью останавливался, когда пространство имен не найдено, измените функцию Namespace_Check на что-то вроде этого: 

Function Namespace_Check { 
     Write-Host "Checking available namepace" -ForegroundColor Green

     if (!((Get-CimInstance -namespace "root\cimv2" -ClassName __NAMESPACE).Name -match 'NV')) {
         # if we got here, the namespace is not found
         # output the current version, then stop the script
         $driver = Get-WmiObject Win32_PnPSignedDriver| 
                        Select-Object devicename, driverversion | 
                        Where-Object {$_.devicename -like "*nvidia*"}

         Write-Host "If Stopped, install latest NVIDIA driver from SWE"

         if ($driver) {
            Write-Host "Current driver(s)" -ForegroundColor Yellow
            $driver | Format-Table -AutoSize
         }
         else {
            Write-Warning "No nvidia drivers found"
         }

         Write-Host "Script Complete" -ForegroundColor Green 

         # stop the script
         exit
     }
}

В вашей версии вы пытаетесь записать в консоль после вы вышли из функции, используя оператор return.Поэтому эти строки никогда не будут выполнены.

В качестве альтернативы, вы можете заставить функцию Namespace_Check возвращать значение $ true или $ false, напримерthis: 

Function Namespace_Check { 
     Write-Host "Checking available namepace" -ForegroundColor Green

     if (!((Get-CimInstance -namespace "root\cimv2" -ClassName __NAMESPACE).Name -match 'NV')) {
         # if we got here, the namespace is not found
         # output the current version, then stop the script
         $driver = Get-WmiObject Win32_PnPSignedDriver| 
                        Select-Object devicename, driverversion | 
                        Where-Object {$_.devicename -like "*nvidia*"}

         Write-Host "If Stopped, install latest NVIDIA driver from SWE"

         if ($driver) {
            Write-Host "Current driver(s)" -ForegroundColor Yellow
            $driver | Format-Table -AutoSize
         }
         else {
            Write-Warning "No nvidia drivers found"
         }

         Write-Host "Script Complete" -ForegroundColor Green 

         return $false
     }
     return $true
}

и в основной части вашего скрипта выполните 

if ($isAdmin) {
    if (Namespace_Check) {
        Write-Host
        InstallSWE
        Write-Host
        CheckNVIDIADriver
        Write-Host
        SetNVIDIA3DGlobalPreset
        Write-Host
        SetScreenSaver
        Write-Host
        ChangePowerSettings
        Write-Host
        ChangeVirtualMemory
        Write-Host
        EnableRDP
        Write-Host
    }
}
else {
    Write-Warning "Administrator rights is required to run this script"
    Write-Host
}

Write-Host "Press any key to continue ..."
$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
# end of script

. Это приведет к корректному завершению скрипта вместо использования оператора exit.
