powershell embedding one variable in another one

问题

In powershell , for a complicated reason an application needs a 6 character string as a sort of handle (Eg: abcdef) for a long asynchronous operation. I perform this using

$replaceHandle = "abcdef"
start-Job -handle $replaceHandle

The application stores the status of the asynchronous job in $abcdef (Prefixes string with $) and i can access parameters of job Status at any time by requesting

Get-Status -ID $abcdef.ID

Problem for me in my code is i am not able to get this $abcdef.ID properly I have tried $($jobVar.ToString()).ID - this gives blank/errors out maipulating $$jobVar.ID actually gives $'abcdef'.ID

How do i manage to get value of ($abcdef.ID) appropriately ?

回答1:

It because $jobVar is first interpreted :

try :

write-host "the value is $($jobVar.ID)"

回答2:

(Get-Variable $b -ValueOnly).Id

This worked
