control-flow - 我对 Powershell 脚本中条件语句的行为感到困惑

Question

我正在测试我的脚本的控制流，看看我的方向是什么，得到了一些奇怪的结果。起初一切似乎都正常工作，但我决定先测试另一个 if 语句，然后在这次运行之后我再次运行脚本并遵循另一个现在不起作用的 IF 语句。我没有更改脚本中的任何内容。我认为我的其中一个陈述一定有问题。第一个条件语句使用嵌套的 IF 语句，第二个不使用。两种方式都适用于第一次运行。下面的链接可以查看输出。脚本运行

更新脚本：

$Folderperm = $null
$confmfoldper = $null
$Folder = $null

if ($ImportPath -ne "") {
    $ImportCSV = Import-Csv $ImportPath
    }

    $confmailbox = Read-Host -Prompt "The permission you set here will give the User/s the same level of access to the other folders and calendar within the mailbox. Continue?[Y/N]"
    }

     switch($Boxperm)

    $Folderperm = Read-Host  -prompt "Enter corresponding number"
    $Folder = Read-Host “Enter the FOLDER NAME ( Examplles : Inbox,calendar…)”
    $foldername = $Displayname.WindowsEmailAddress + “:\” + $Folder
    
    }

    switch($Folderperm)
    {
    {$Folderperm -eq 1} {$Folderperm = 'Author' ; break; }
    {$Folderperm -eq 2} {$Folderperm = 'Contributor' ; break;}
    {$Folderperm -eq 3} {$Folderperm = 'Editor' ; break;}

    }



    if ($confmailbox -like 'y' -and $ImportPath -eq "") {
    Add-MailboxPermission -identity $Displayname.Name -user $Useremail -AccessRights $Boxperm -InheritanceType All -Automapping $false
    }

    If ($Folder -ne “” -and $ImportPath -ne "") {
    Add-MailboxFolderPermission $foldername -User $Useremail -AccessRights $Foldperm -confirm:$true
    }

     if ($confmailbox -like 'y' -and $ImportPath -ne "") {
    
     foreach ($User in $ImportCSV){
     Add-MailboxPermission -identity $Displayname.Name -user $User.Email -AccessRights $Boxperm -InheritanceType All -Automapping $false
    }
     }


If ($Folder -ne “” -and $ImportPath -ne "") { 

foreach ($User in $ImportCSV) {
    Add-MailboxFolderPermission $foldername -User $User -AccessRights $Foldperm -confirm:$true
        }
    }

我有机会使用嵌套的 ForEach 语句测试ImportCSV参数。但是，该脚本使用 -Useremail 参数工作。
