Powershell GUI返回文件路径

这将写出ListViewItem:{test}

我需要path2作为我选择的文件夹的文件路径

---

我已经编写了一个gui windows资源管理器，这样我可以搜索文件和文件夹。按钮3是选择。此按钮应获取所选内容的值并将其分配给path2，然后关闭gui。然而，我很难意识到这一点。如果您更改脚本行，则可以编写所选的foldername，我们将非常感谢您提供的任何帮助

从

美好的多谢了，真是妙不可言。您介意解释一下$script:before path2的作用吗？它在脚本级别设置变量。如果您不使用它，$path2将在您退出该函数后立即消失。
