Monitoring File Changes in C# [duplicate]

This question already has answers here: Notification when a file changes? (3 answers) Closed 6 years ago.

I'm using C# for a mini project of mine, I am trying to monitor files that are changed, Deleted, And/or created. And exp开发者_运维百科ort that to a file. But I am not quite sure how to monitor files. Any ideas?

You can use the FileSystemWatcher class to monitor file creation, modifications, deletions and renames.

You have the following events available:

• Changed
• Created
• Deleted
• Renamed

you can only monitor one Directory with FSW, if you want more you may have to make multiple instances of FSW. It monitors the directory not the file; if the file is moved (changed+created; changed+renamed) then you need another FSW for that destination folder.
