如何从 PowerShell 的列表框中捕获选定的值？

Question

我正在尝试创建一个弹出窗口，要求用户 select 一个部门，然后根据该部门运行一个 selection Choco 命令来安装每个部门需要的软件使用。我运行遇到了一个问题，它没有返回 selected #var。

到目前为止的疑难解答表明，无论我 select 在列表中的什么项目，它都只是运行第一个 IF 部分下的命令，然后停止。

我试图缩减我的代码，只要求它打印每个业务部门，这样我就可以检查列表框设置，但我找不到我缺少的东西。

简单的 PowerShell 错误，但 = 是一个赋值：

$TSDepartment -eq "Admin-Support"

那是你的比较运算符。

补充说明：

-ne -> 不等于
-ceq -> 区分大小写等于
-cne -> 大小写不等于
