Many users will write to the same logfile, how can I make sure there is no
conflict when there are some concurrent access? I can't find a method to check
if the file is open or not.
Would you please add some sample code based on the following code? Thank you
so much!
StreamWriter sw=File.AppendText (sLogFile);
sw.WriteLine (DateTime.Now.ToLongTimeString ()+" "+sText);
sw.Flush ();
sw.Close ();

open it exclusively for write;
or creating a reader/writer threading model to handle concurrency conflicts...
this is a very typical situation

check
