如何从PowerShell中的列表框中捕获所选值？

我试图创建一个弹出窗口，要求用户选择一个部门，然后根据该部门运行Choco命令，以安装每个部门需要使用的软件。我遇到了一个问题，它没有返回所选的#var

到目前为止的故障排除表明，无论我在列表中选择什么项目，它都只运行第一个IF部分下的命令，然后停止运行

我试图缩小代码的比例，让它只打印每个业务部门，这样我就可以检查列表框设置，但找不到缺少的内容

PowerShell很容易出错，但=是一项任务：

$TSDepartment -eq "Admin-Support"

这是比较运算符

进一步说明：

• -不等于
• -ceq->区分大小写等于
• -cne->Case Not Equals

谢谢！！我还让人将我的Var称为错误的，并意外地将其编辑掉了#结果Var$TSDepartment=$objListBox.Text

它是
-ne
而不是
-neq
。
