What's the best practice to recover from a FileSystemWatcher error?
.net, c#, exception, filesystemwatcher
Solution
Depends on the error surely?
- If it is too much data because the buffer was overrun (many changes) do a list directory and grab the changes you're after.
- If it is too much data because you're not processing the FileSystemWatcher events quickly enough, ensure you're processing it efficiently.
- Deleted directory, can't do anything about it other than disposing the FileSystemWatcher, or maybe watching the parent for a recreation of that directory name again.
Problem
After a `FileSystemWatcher.Error` event was raised, I have no clue about what to do next. The exception can be a [relatively] minor one, such as too many changes at once in directory which doesn't affect the watcher's watching process, but it can also be a big issue - such as the watched directory being deleted, in which case the watcher is no longer functional. My question is what is the best way to handle the Error event?
