ErrorActionPreference和ErrorAction静态地进行Get-PSSessionConfiguration [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...

为什么不工作 - GetAPSSessionConfiguration的ErrorAction SilentContinue）

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

更新：

/ p>

Now,

$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 - SilentlyContinue;

1 - SilentlyContinue;
2 - SilentlyContinue;

这个参考：

可以使用 ErrorAction 无处不在的参数使用参数值 SilentlyContinue 来静默非终止错误，它可以用于使用参数值 Stop 将非终止错误转换为终止错误。然而，它不能帮助您忽略终止错误，在这种情况下，Stop-Transcript会引发终止错误。如果你想忽略，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

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 

或使用try-catch

Or use try-catch

try { 

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

} 
catch {

}
