Question

In some scenario, I need to call FileWatcher onDelete function in my application.
The below code works as expected. Please let let me know if there any better way to do this.

         string path = @"C:\File\Test";
         string part1, part2;
         part1 = path.Substring(0, 3); //C:\\
         part2 = path.Substring(3  // File\Test
var fseArgs = new FileSystemEventArgs(WatcherChangeTypes.Deleted, part1, part2);
onDeleted(path,fseArgs); //FileWacther Delete method

Answer 1

Presumably onDeleted is your own method. What does that do? I would expect it to quite possibly be simpler to have another method which wasn’t related to FileSystemEventArgs, call that directly in your “scenario”, and then make your FileSystemEventWatcher handler call it too. Avoid coupling to FileSystemEventWatcher when you don’t really need it.

Additionally, you shouldn’t just use Substring like this to perform file system path manipulation – it ends up being very brittle. I strongly suggest you use the methods in Path.

On the other hand, you haven’t really told us much about your context…
