The events are equal only if they are of the same type (reO1 and reO2 RenamedEventArgs reO2 = delayedEvent._args as RenamedEventArgs RenamedEventArgs reO1 = _args as RenamedEventArgs įileSystemEventArgs eO2 = delayedEvent._args Return false // this is not null so they are different Public virtual bool IsDuplicate(object obj)ĭelayedEvent delayedEvent = obj as DelayedEvent Public DelayedEvent(FileSystemEventArgs args) / Only delayed events that are unique will be fired. Private readonly FileSystemEventArgs _args / This class wraps FileSystemEventArgs and RenamedEventArgs objects and detection of duplicate events. Unfortunately this is not a simple function thus i will include complete code. You have to create a queue and store all events there and if a time interval passes then raise the appropriate event. You might also get false events when the file is not in read mode (such as when you copy a file). ![]() The following code is the revised class constants, class variables, and class constructor.I have stumbled upon this problem myself twice and i created a class that helps you get only one event at a time. For the revised start to work, the FileWatcher constructor should not instantiate a new FileSystemWatcher. In the revised start, that is repaired by removing the event handlers if file_watcher is not null.īy implementing this revision, all that needs be done is to invoke start ( ) appropriately in NotAccessibleError. You may be having problems by not deleting event handlers before adding new ones. New FileSystemEventHandler ( OnCreated ) It seems that the error is being thrown by the 2 obj’s but only the latest one is being stored and used by booth. So when the automatically recovers it creates 2 new watchers for the second directory. If I only use one obj its works fine and recovers ok, but if I instance more than one obj of the class when he get an error it:Īssumes that there where 2 (for example) watcher that lost network but the information that I can see is only for the latest one that I have instanced.
