从Powershell中的多个下拉列表返回多个值

我对powershell是个新手。我的任务是创建一个GUI，它从多个下拉列表中接收多个字符串，并根据这些选择重命名计算机。我用两个选项测试它，$FacilityInitials和$BuildingNumber。Powershell仅返回$BuildingNumber选项

我回来可能有问题吧？我应该如何正确地执行多个返回功能？谢谢！：）

我试着检查打字错误

不支持多选，请使用

列表框

，如果这是一个新项目，我建议使用WPF。它将更易于维护，并且有一个交互式编辑器，可以通过Visual Studio为您提供xml定义。@MathiasR.Jessen谢谢！成功实现了基于

的GUI。
