I am using FileSystemWatcher in a Windows service on .Net 2.0 C#
application. When I see

ChageType="Created" I copy the file over to a database. About 30-40%
of the time I am getting a strange error which I am including below. I
am suspecting that the event is triggered before file is closed and
hence this error is happening. the symptom is that the file is not
copied to destination after the handler is done. Does anybody knwo how
to check to see if the file is closed before takign action on
FileSystemEventHandler is being fired?

here is what I have

protected override void OnStart(string[] args)
       {
           FSW.Changed += new FileSystemEventHandler(FSW_Changed);
           FSW.Created += new FileSystemEventHandler(FSW_Changed);
           FSW.Deleted += new FileSystemEventHandler(FSW_Changed);
           FSW.Renamed += new RenamedEventHandler(FSW_Renamed);
           FSW.Path =
ConfigurationSettings.AppSettings["HostDirectory"].ToString();
           FSW.Filter = "*.*";
           FSW.IncludeSubdirectories = true;
           FSW.NotifyFilter = NotifyFilters.LastAccess |
NotifyFilters.LastWrite
               | NotifyFilters.FileName |
NotifyFilters.DirectoryName;

           //Begin monitoring.
           FSW.EnableRaisingEvents = true;
       }

This is the error I see in the log file
