FileSystemWatcher Changed event is raised twice

Question

I have an application where I am looking for a text file and if there are any changes made to the file I am using the OnChanged eventhandler to handle the event

Answer 1

I have created a Git repo with a class that extends FileSystemWatcher to trigger the events only when copy is done. It discards all the changed events exept the last and it raise it only when the file become available for read.

Download FileSystemSafeWatcher and add it to your project.

Then use it as a normal FileSystemWatcher and monitor when the events are triggered.

var fsw = new FileSystemSafeWatcher(file);
fsw.EnableRaisingEvents = true;
// Add event handlers here
fsw.Created += fsw_Created;
