Get-PSSessionConfiguration 的 ErrorActionPreference 和 ErrorAction SilentlyContinue [英] ErrorActionPreference and ErrorAction SilentlyContinue for Get-PSSessionConfiguration

问题描述

我的情况:

$ErrorActionPreference = "Stop";
"1 - $ErrorActionPreference;"
Get-ChildItem NoSuchFile.txt -ErrorAction SilentlyContinue;
"2 - $ErrorActionPreference;"
Get-ChildItem NoSuchFile.txt -ErrorAction Stop;
"3 - $ErrorActionPreference;"

输出:

1 - 停止；
2 - 停止;
并显示错误...

1 - Stop;
2 - Stop;
and display an error...

现在，

$ErrorActionPreference = "Stop";
"1 - $ErrorActionPreference;"
(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)
"2 - $ErrorActionPreference;"

输出:

1 - 停止；
并显示错误...

1 - Stop;
and display an error...

为什么 -ErrorAction SilentlyContinue) 对于 Get-PSSessionConfiguration 不起作用?

Why doesn't work -ErrorAction SilentlyContinue) for Get-PSSessionConfiguration ?

更新:

现在，

$ErrorActionPreference = "Continue"
"1 - $ErrorActionPreference;"
(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)
"2 - $ErrorActionPreference;"

输出:

1 - 继续；
2 - 继续；

1 - Continue;
2 - Continue;

现在，

$ErrorActionPreference = "SilentlyContinue"
"1 - $ErrorActionPreference;"
(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)
"2 - $ErrorActionPreference;"

输出:

1 - SilentlyContinue;
2 - 静默继续；

1 - SilentlyContinue;
2 - SilentlyContinue;

这个参考:

ErrorAction 无处不在的参数可用于使用参数值 SilentlyContinue 来消除非终止错误，并且可用于将非终止错误转换为使用以下方法的终止错误参数值Stop.但是，它无法帮助您忽略终止错误，在这种情况下，Stop-Transcript 会引发终止错误.如果您想忽略，请使用 try/catch 例如:

The ErrorAction ubiquitous parameter can be used to silence non-terminating errors using the parameter value SilentlyContinue and it can be used to convert non-terminating errors to terminating errors using the parameter value Stop. However it can't help you ignore terminating errors and in this case Stop-Transcript is throwing a terminating error. If you want to ignore, use a try/catch e.g.:

try { Stop-Transcript } catch {}

推荐答案

适合我的解决方案:

$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
   WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {        
   #Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
$ErrorActionPreference = $old_ErrorActionPreference 

或者使用 try-catch

Or use try-catch

try { 

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)

} 
catch {

}
