Can logging to text file in ASP.net WEb server cause locks
Thi is my code:
var outStream = new FileStream(Server.MapPath("~\\bin\\error.txt"), FileMode.Append, FileAccess.Write, FileShare.ReadWrite);
As you see
FileShare is both read and write.
So far I have not seen any issues. Are you aware of possible issues using this method. (I do not want to log error to windows event)
Best How To :
Not 100% sure I understand what you are asking, but any time something writes to a file, the file is locked by that application for the period of time that it takes to complete the write. If there is another application writing to the same file at times, there will be the potential for conflict. If both applications are coded to handle conflicts of this nature, then all will be fine. So if you are coding to handle this situation, you would put the write method in a TRY block within a WHILE block. If an error occurs writing, then it would stay in the while block and pause for a second or something and then try again. Once the write is successful, break out of the while block. You may also want to put in a counter and limit the number of tries.
Just be aware that if you do this that the thread will sit here until the write is successful, so if you don't want this to hold up your application it needs to be done with another thread.
