GetWMICOMException
は終了しないエラーです。つまり、デフォルトの$ErrorActionPreference
がContinue
の場合、try
ブロック内のコードはその後も実行を継続します例外をエラーとして書き出す
Get-WmiObject
呼び出しを try-catch
ブロックで囲みますが、-ErrorAction
がStop
に設定されていることを確認してください:
# Try-Catch block starts
try
{
# Call Get-WmiObject
Get-WmiObject -ComputerName $computer -Class "Win32_NetworkAdapter" -ErrorAction Stop
}
# If an Exception of the type COMException is thrown, execute this block
catch [System.Runtime.InteropServices.COMException]
{
# You can inspect the error code to see what specific error we're dealing with
if($_.Exception.ErrorCode -eq 0x800706BA)
{
# This is instead of the "RPC Server Unavailable" error
Write-Error -Message "Your own custom message"
}
else
{
Write-Error -Message "Some other COMException was thrown"
}
}
# If any other type of Exception is thrown, execute this block
catch [System.Exception]
{
Write-Error -Message "Some other exception that's nothing like the above examples"
}
# When all of the above has executed, this block will execute
finally
{
Write-Verbose "Get-WmiObject object was executed"
}
または、スクリプトを実行する前に$ErrorActionPreference
をStop
に設定することもできます。
# Before the rest of the script
$ErrorActionPreference = Stop
