Powershell 如何动态更改变量值？

我的powershell脚本中有以下变量

$Buildlog="FormalBuild.log"
$Logger="/flp1:Append;LogFile=$Buildlog;Verbosity=Diag;"

#Logger will use Formalbuild.log
Write-host $logger 

$Buildlog="Dailybuild.log"

#Logger should use Dailybuild.log file
Write-host $logger

$logger始终显示Formalbuild.log。我不想重新定义记录器。有没有办法使$logger值动态化

看看这里的例子：

那么代码段可能是：

$Buildlog="FormalBuild.log"

$logger = Set-PSBreakpoint -Variable logger -Mode Read -Action { $global:logger = "/flp1:Append;LogFile=$Buildlog;Verbosity=Diag;" }

#Logger will use Formalbuild.log
Write-host $logger 

$Buildlog="Dailybuild.log"

#Logger should use Dailybuild.log file
Write-host $logger
