Question

我在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。我不想再重新定义记录器。有没有办法让$ logger值动态化？

请在此处查看示例：http://powershell.com/cs/blogs/tips/archive/2011/10/31/creating-intelligent-variables.aspx

然后代码段可能是：

$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

如何动态更改变量值？
