In C#/.NET (on Windows) is there a way to read a \"growing\" file using a file stream? The length of the file will be very small when the filestream is opened, but the file
The way i solved this is using the DirectoryWatcher / FilesystemWatcher class, and when it triggers on the file you want you open a FileStream and read it to the end. And when im done reading i save the position of the reader, so next time the DirectoryWatcher / FilesystemWatcher triggers i open a stream set the position to where i was last time.
Calling FileStream.length is actualy very slow, i have had no performance issues with my solution ( I was im reading a "log" ranging from 10mb to 50 ish).
To me the solution i describe is very simple and easy to maintain, i would try it and profile it. I dont think your going to get any performance issues based on it. I do this when ppl are playing a multi threaded game, taking their entire CPU and nobody has complained that my parser is more demanding then the competing parsers.
