windows - 如何在 powershell 中关闭 Windows 窗体？

Question

我正在编写一个脚本，在这个例子中的计算器上对某个程序进行访问控制

当您启动程序(脚本)时，脚本会生成一个包含用户名和时间戳的文本文件。如果第二个人尝试访问，脚本会检查此文本文件是否存在，并给出用户名和时间戳，并希望稍后尝试。如果该文件不存在，您可以访问该程序并生成该文件。当您关闭程序时，文件将被删除。

我正在使用一些 Windows 窗体来包含忽略函数并退出脚本。

问题是在您点击两个窗体上的忽略按钮后，Windows 窗体不会关闭。

我不知道如何修复它。

Answer 1

这与调用 calc.exe 时使用的 -Wait 参数有关。您在调用 taskmgr.exe 的函数中不会遇到问题，因为您没有使用 -Wait。

我还将 $Form1 和 $Form2 定义从局部函数范围中取出，以便每个人都可以全局访问它们。

相当疯狂地猜测，我想 -Wait 参数不允许前面的代码完成执行，直到函数退出，即框架正在决定某些引用仍然需要存在，而您调用的进程存在。
