C# - File Watcher as a windows service watching multiple directories

Question

I have a problem that I can't seem to find a solution for. I am writing a file watcher Windows Service in C# using FileSystemWatcher. I would like to watch multiple independent directories, I have the directories to watch and some other settings in a xml file. The program reads in the xml, creates the appropriate number of FileSystemWatchers and stores these system watchers in a dictionary with a randomly generated id number (as the keys). The problem that I am having is that only the first FileSystemWatcher is responding to files being created/deleted/updated ect. I know the others have been create because the entries are in the dictionary. I know EnableRaisingEvents = true because all of the FileSystemWatcher are created the same way via a loop. I have no idea how to get multiple file watchers working correctly, and I would like to avoid threads if possible. If anyone has any ideas or resources to look at, that would be greatly appreciated.

Answer 1

Im afraight you háve to instantiate some kind of thread pool or task factory because a filewatcher can only watch one file in a thread.

However this posting has a very nice example of doing so: How to assign separate thread for each File System Watcher?

Hope this helps
