The process cannot access the file 'C:\PCLtoMove\print.pcl' because it is being used by another process. Windows service

Question

I have a folder named PCLtoMove. I have applied a filewatcherSystem in this folder to move files from this folder to another folder. first time when I start windows service It works fine but from next time it gives exception-

The process cannot access the file 'C:\PCLtoMove\fileName.pcl' because it is being used by another process.

my code to move file is -

 private void SavionFileWatcher_Created(object sender, System.IO.FileSystemEventArgs e)
    {
        try
        {
            string sourcePath = e.FullPath;
            string destination = ConfigurationManager.AppSettings["destination"] + e.Name;
            File.Move(sourcePath, destination);

        }
        catch (Exception ex)
        {
            this.EventLog.WriteEntry(ex.Message, EventLogEntryType.Information);
        }

    }

please tell me whats wrong I am doing.

Answer 1

I got the solution by adding following code to the above code. Its confirms that the file is completely moved or created.

 FileStream fs = new FileStream(sourcePath, FileMode.Open, FileAccess.ReadWrite);
                    fs.ReadByte();
                    fs.Seek(0, SeekOrigin.Begin);
                    fs.Dispose();
                    File.Move(sourcePath,destination);
                       break;
