Powershell error handling: do something if NO error occured

问题

I've been searching around for this but can't seem to find it. I'm having a script with a try {} catch {} statement. I'd like to add an action if NO error occured.

Eg

try { something }
catch { "Error occured" }
if (!error) {
"No Error Occured"
}

How can I test if no error occured in the statement?

Thanks in advance

回答1:

Chek the automatic-variable $error after cleared

$error.clear()
try { something }
catch { "Error occured" }
if (!$error) {
"No Error Occured"
}

Another way:

$ErrorOccured = $false

try 
{ 
   $ErrorActionPreference = 'Stop'
   ...something...
}
catch
{
   "Error occured"
   $ErrorOccured=$true
}

if(!$ErrorOccured) {"No Error Occured"}

.

What about,

something
If ($?)
{
    "No error"
}
Else
{
    "Error"
}

This will work for non terminating errors too.
