Use Powershell variable in another variable / in parameter of a commandlet-CodePudding

I would like to use a variable with variable name in 2 examples

Example 1:

$Myvalue1 = "$AutomateProcessing"

I want to put $false in my variable $AutomateProcessing using

$"$Myvalue1" = $false

(in place of $AutomateProcessing = $false)

Example 2:

$Myvalue2 = "AutomateProcessing"

Get-EXOMailbox $MyMBX | set-CalendarProcessing -$Myvalue2 $MyConfig

(in place of Get-EXOMailbox $MyMBX | set-CalendarProcessing -AutomateProcessing $MyConfig)

With this, I could create a loop with a lot of parameters I want to modifiy.

Is it possible to do with PowerShell?

Thank you in advance

You can use the cmdlet set-variable.

Use switch "Variable" to define your variable (without $ sign) and the switch "Value" for the value.

$AutomateProcessing=$true
$Myvalue1 = "AutomateProcessing"
Set-Variable -Name $Myvalue1 -Value $false
Out-Host -InputObject "Variable $Myvalue1 is now set to $AutomateProcessing"

The result:

Variable AutomateProcessing is now set to False

CodePudding user response：

The first part is not clear.

On the second example you mentioned, You can achieve this if you store the entire commandlet as a string first and use Invoke-Expression to trigger it.

Something like this.

[string] $FullCommandlet = "Get-EXOMailbox $MyMBX | set-CalendarProcessing -$Myvalue2 $MyConfig"

Invoke-Expression -Command $FullCommandlet

Hope that helps !

Try Splatting your parameters in from a hashtable

Param(
[array]$MyMBX = <array>,
[String]$AddOrganizerToSubject = <value>,
[bool]$AutomateProcessing = <value>,
[bool]$AllowRecurringMeetings = <value>
)
Foreach($mbx in $MyMBX){
$Myconfig = @{'Identity' = (Get-EXOMailbox -Identity $mbx)
             'AutomateProcessing' = $AutomateProcessing 
             'AddOrganizerToSubject' = $AddOrganizerToSubject
             'AllowRecurringMeetings' = $AllowRecurringMeetings
              }# etc etc
Set-CalendarProcessing @Myconfig
}
