我正在尝试在powershell脚本中创建一个类似CUI的应用程序。例如，显示大约7个选项 - 每个选项映射到数字字符。显示提示，管理员可以键入相应的数字字母以选择选项。
我正在使用Do-While循环和Switch语句来完成此任务。对于每个选项，我已经使用Exe命令和错误捕获机制创建了一个函数。
这个脚本可以解决任何问题，但问题是我在函数内部使用的可执行文件只显示结果5或10次，没有显示结果，甚至没有错误。即使在从脚本终止之后，同一控制台中的所有exe文件也会继续这种情况。
如果我关闭powershell控制台并打开一个新的，可执行文件可以正常工作5到10次，然后重新开始。我无法确定导致此问题的原因。

我在Win7机器上试过你的脚本。我没有DFSCMD.EXE存在，所以每次脚本执行它时我都会收到错误。除此之外，脚本运行了30多次，没有任何麻烦。
我建议注释掉DFSCMD.EXE的调用表达式，看看它是如何工作的。如果它一致地工作，我会将其添加回来，然后在进行5-10次调用时观察Powershell和任务管理器中的整体系统性能。在Powershell下，我会寻找内存使用，句柄和线程。我预计Powershell会增加一些内存使用量，但不会很大，如果PS闲置，它应该会回落。此外，DFSCMD.EXE的每个实例在退出后都应从taskmgr中消失。
您还可以使用Process Explorer并深入了解。例如，procexp将让您查看进程的线程堆栈。一旦你进入“不工作状态”，你可以通过查看PS的线程来获得关于发生了什么的提示。您需要加载符号以使procexp在堆栈上显示符号。我认为procexp的帮助告诉你如何做到这一点。
除此之外，我将打破一个调试器......让好时光滚动
