Does FileSystemWatcher create its own thread?

Question

I want this work to be done in a different thread but do i have to create a thread or does it do all the work on different threads?

Like:

Thread fileThread = new Thread(() =>
{
    FileWatcher = new FileSystemWatcher();

    FileWatcher.Created += OnFileEvent;
    FileWatcher.Deleted += OnFileEvent;
    FileWatcher.Renamed += OnRenameEvent;
    FileWatcher.EnableRaisingEvents = true;
});

fileThread.Start();

Solution

You don't have to create a thread. The events will be called on a separate thread automatically.

ok perfekt, i got another question: Once i stop the watcher, i set enableraisingeevents = false, but when i want to start the watcher again , i dont know if i should just enableraisingevents=true or if i should create a new instance of the filesystemwatcher like the above code, what do you think? Thank you

@syncis: If you keep the instance, you can just turn it on again.

Ok my concern was that i dont want it to do any work at some point and if its enableraisingevents = false , i thought it would do all the work but just not raise the events.

@syncis: If you are concerned about that, then you should create a new object instead. However, just turning off enableraisingevents will not stop it from listening for changes, you should call Dispose when you don't use it any more.

How would the debugger handle that?

@Guffa Why do you think that turning off EnableRaisingEvents will not stop it from listening? What I can see in the source code is that it will.
