这里有一个Linux用户尝试在PowerShell中编写一个脚本来自动执行从Windows服务器到远程服务器的SFTP传输。（虽然我还有一些测试要做）。我当前的问题是在脚本运行一次之后完成。我需要FileSystemWatcher在每次发现新文件创建时运行。我意识到这是因为exit，但当我删除该部分，用户放入一个目录时，它会循环遍历目录中的每个文件，并一遍又一遍地上传目录中的每个文件。我需要它做的是运行一次该过程，然后保持活动状态以侦听另一个文件创建事件。我的问题可能是我在Windows中编码的工作有限，所以任何帮助都是感激的！
是的，我意识到在处理我的文件和我的文件夹时重复的代码是多余的。我很可能会把这部分代码做成一个函数，它接受的参数取决于它是被给定的文件还是文件夹。
我张贴我的整个代码的情况下，它可以帮助别人以后
