PowerShell 2.0 and how to handle exceptions ?
- by Primoz
Why I get error message printed on the console when running these two simple samples ?
I want that I get "Error testing :)" printed on the console insted of:
Get-WmiObject : The RPC server is
unavailable. (Exception from HRESULT:
0x800706BA) At line:3 char:15
+ Get-WmiObject <<<< -ComputerName possibly.nonexisting.domain.com
-Credential (Get-Credential) -Class Win32_logicaldisk
+ CategoryInfo : InvalidOperation: (:) [Get-WmiObject],
COMException
+ FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand
or
Attempted to divide by zero. At line:3
char:13
+ $i = 1/ <<<< 0
+ CategoryInfo : NotSpecified: (:) [],
ParentContainsErrorRecordException
+ FullyQualifiedErrorId : RuntimeException
First example:
try
{
$i = 1/0
Write-Host $i
}
catch [Exception]
{
Write-Host "Error testing :)"
}
Second example:
try
{
Get-WmiObject -ComputerName possibly.nonexisting.domain.com -Credential (Get-Credential) -Class Win32_logicaldisk
}
catch [Exception]
{
Write-Host "Error testing :)"
}
Thank you very much!
