在PowerShell腳本中使用時間條件循環

Question

這裏是我的代碼：

 #make sure deployment is in running state 
$deployment = Get-AzureDeployment -servicename $_serviceName -slot $_slotName 
Write-Host "$_serviceName is in state $($deployment.status)" 
while ($deployment.Status -ne "running") 
{ 
    Write-Host "wait 5 seconds before trying again" 
    Start-Sleep -s 5 
    $deployment = Get-AzureDeployment -servicename $_serviceName -slot $_slotName 
    Write-Host "$_serviceName is in state $($deployment.status)"   
} 

我想提出一個條件，while循環，如果它已經運行了可以說2小時，然後就應該退出。似乎無法找到如何啓動計時器並在PowerShell中保存記錄。

Answer 1

在這個例子中，我所做的只是在While循環之前添加一行，以確保在While循環期間2小時還沒有通過。

根據您希望break何時退出流程，這可能是最好的選擇，因爲一旦您打滿整整2個小時，它就不會再次啓動新的循環，並且循環將被定爲重新開始。

#make sure deployment is in running state 
$deployment = Get-AzureDeployment -servicename $_serviceName -slot $_slotName 
Write-Host "$_serviceName is in state $($deployment.status)" 
$StopWatch = [System.Diagnostics.Stopwatch]::StartNew() #new code 
while (($deployment.Status -ne "running") -and ($StopWatch.Elapsed.Hours -lt 2)) #new code 
{ 
    Write-Host "wait 5 seconds before trying again" 
    Start-Sleep -s 5 
    $deployment = Get-AzureDeployment -servicename $_serviceName -slot $_slotName 
    Write-Host "$_serviceName is in state $($deployment.status)"   
}
