如何將遠程PowerShell會話的變量返回到本地PowerShell會話

Question

我有一個PowerShell腳本來創建新的PowerShell會話。我需要將本會話中創建的衆多變量中的一個變量返回到本地/呼叫會話。這裏是我的PowerShell腳本：

param 
(
[string]$user, 
[string]$password 
) 

$secure_password = ConvertTo-SecureString $password -AsPlainText -Force 
$cred = New-Object System.Management.Automation.PSCredential $user, $secure_password 

$new_session = New-PSSession -Credential $cred 

$script = { 
$var1 = 0 
$var2 = a 
} 

Invoke-Command -Session $new_session -ScriptBlock $script 

Write-Host ($var2) 

當腳本執行Write-Host ($var2)，它不爲$ VAR2打印任何價值。我怎樣才能返回$ var2到本地會話？

param 
(
[string]$user, 
[string]$password 
) 

$secure_password = ConvertTo-SecureString $password -AsPlainText -Force 
$cred = New-Object System.Management.Automation.PSCredential $user, $secure_password 

$new_session = New-PSSession -Credential $cred 

$script = { 
    $var1 = 0 
    $var2 = a 
    $var2 
} 

$varFromSession = Invoke-Command -Session $new_session -ScriptBlock $script 

Write-Host $varFromSession 

單從會話的腳本塊返回變量，無論是與Write-Output或return或只使用變量另一個命令，因爲我已經證明。 Invoke-Command的返回值將是腳本塊寫入管道的任何值。
