Log file availability issue

During the application running the log file is locked. I am trying to email the log file inside the application while the application is running.
Do I have any way to close the log file so it is unlocked, so that I can get the log file and email it?

Thanks

Greg

I am a total idiot. Just noticed this came to the log4net list, not
log4php... :D

Sorry guys.

Regards,
Ivan

You can use a minimal lock on your FileAppender:

<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

but it'll slow things down because it will open and close the file with each write. I've used code like this before to open a locked file:

// from http://www.ericbt.com/Blog/48
using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
  using (StreamReader streamReader = new StreamReader(fileStream))
  {
    logFileText = streamReader.ReadToEnd();
  }
}

Hi Greg,

You should be able to read the file while the program is running. Check out
this quick example:
https://gist.github.com/ihabunek/5765463

It's reading the file contents while logging to it in.

The appender acquires a lock before writing to the file, but releases it
after writing. The log file should not be locked.

Now, I don't know how you're accessing the file, or how you're sending it
via email. Maybe you can send me a code snippet which demonstrates your
problem?

Best regards,
Ivan
