變數$NestedPromptLevel可協助您追蹤提示層級。 您可以建立包含此值的替代 PowerShell 命令提示字元,使其永遠可見。 $null $null是包含Null或空值的自動變數。 您可以使用這個變數來表示命令和文稿中不存在或未定義的值。 PowerShell 會將$null視為具有值或佔位符的物件,因此您可以使用$null來代表值集合中的空白...
您可以使用自動變數來尋找巢狀層級$NestedPromptLevel。 自動變數$PSDebugContext會在本機範圍中定義。 您可以使用變數的存在$PSDebugContext來判斷您是否在調試程式內執行。 例如: PowerShell if($PSDebugContext) {"Debugging"}else{"Not Debugging"} 您可以在偵錯中使用 變數的值$PSDebugContext。
$NestedPromptLevel- 正常访问。 $null- 正常访问。 $PID- 改为访问$Script:PID。 $PROFILE- 改为访问$Script:PROFILE。 $PSBoundParameters- 请勿使用此变量。 它适用于 cmdlet 和函数。 在类中使用它可能会产生意外的副作用。 $PSCmdlet- 请勿使用此变量。 它适用于 cmdlet 和函数。 在类中使用它可能会产生...

running in parallel, continue to run unless they also encounter a terminating error. The terminating error is written to the error data stream as anErrorRecordwith aFullyQualifiedErrorIdofPSTaskException. Terminating errors can be converted to non-terminating errors using PowerShelltry/catchortrapblock...
I have a different opinion on this. By enablingStrictMode, you mean to catch the the cases where a non-existing member gets accidentally dereferenced at runtime, and that's what it does even with the null-conditional operator, isn't it?
I tried this with running 5 jobs, each with 10 nested jobs, and still got an error. I think even more than usual, but could just be coincidental. Ha, you beat me to this by like 10 minutes! :) Was just coming to post the same, I'm getting the same results. I think I have ...
There are a number of code snippets in this section. They’re there for you to try and look at the results. PowerShell is best learned by doing. We’ll keep meeting these friends in later chapters. I guarantee you’ll use one of these commands at least once in any session when you’...
