推荐答案

FileSystemWatcher与处理更改无关从用户界面.它旨在监视文件系统的更改(因此而得名).您的应用程序需要驱动逻辑来重命名文件-换句话说，它需要执行File.Move将文件从一个文件名重命名为另一个文件名.现在，需要注意的一件事是，这将取决于具有相关权限来重命名文件的用户.根据安全性，可能不允许这样做，因此您的应用程序设计必须考虑到这一点.

File.Move [

The FileSystemWatcher has nothing to do with handling changes from a UI. It is intended to monitor changes to a file system (hence it''s name). Your application needs to drive the logic to rename the file - in other words, it needs to perform a File.Move to rename the file from one filename to the other. Now, one thing to be aware of is that this is going to depend on the user having the relevant permissions to rename the file; depending on security, this might not be allowed, so your application design will have to take this into account.
