Powershell腳本將不會繼續，即使出現錯誤

我已經做了幾個小時的研究，目前卡住了，我看了一堆文件，然後將它傳遞給一些書面函數，我遇到的問題是如果我有200個文件要處理，我不希望每個錯誤都終止腳本，因爲這意味着整個事情需要重新執行。Powershell腳本將不會繼續，即使出現錯誤

所以我想使用Try/Catch或其他任何方式來捕獲錯誤，以便我知道它，但我希望循環移動到下一個項目並處理它。當我在循環中刪除Try..Catch並指定erroraction ='continue'時，它確實繼續，但是因爲數據庫連接仍處於打開狀態，所以所有文件都失敗了。

這裏的任何想法？

因此，目標是在循環過程中，如果遇到文件錯誤，請繼續前進到下一個文件，但突出顯示錯誤。

function GetDatabaseFiles ([STRING]$backupfile) 
 
{ 
 

 
Try 
 
{ 
 

 
$SQLConnection.Open() 
 
$SQLQuery = "RESTORE FILELISTONLY

$SQLCommand = New-Object system.Data.SqlClient.SqlCommand 
 
$SQLCommand.CommandText = $SQLQuery 
 
$SQLCommand.Connection = $SQLConnection 
 
$SQLAdapter = New-Object System.Data.SqlClient.SqlDataAdapter 
 
$SQLAdapter.SelectCommand = $SQLCommand 
 
$DataSet = New-Object System.Data.DataSet 
 
$SqlAdapter.Fill($DataSet) 
 
$SQLConnection.Close() 
 
return $DataSet.Tables[0] | Select-Object LogicalName,PhysicalName,type 
 
}

你的代碼是報價冗長。我在你的循環中看到這個結構：

Try{ 

    Foreach(...){ 
     $dbFiles = GetDatabaseFiles -backupfile $filename #-ErrorAction Continue 
    } 

} 
catch{ 
    ... 
} 
finally{ 
    write-output "script completed" 
}

而是試試這個。 -ErrorAction Stop會將非終止錯誤轉變爲終止錯誤。 Try/catch不適用於非終止錯誤。

Foreach(...){ 

    Try{ 
     $dbFiles = GetDatabaseFiles -backupfile $filename #-ErrorAction Stop 
    } 
    catch{ 

    } 

} 
write-output "script completed"
