Problem with logging exception into txt file

Question

User1594680833 posted

Hi

I am trying to log all my exception  in a txt file on the server. and i am creating a log file for each day,

My problem is i am unable to store two logs of same day in same file,

It always replaces the previous content.

Thanks

 FileStream fs = new FileStream("z:\\Connection_log" + DateTime.Today.ToString("dd-MM-yyyy") + ".txt", FileMode.OpenOrCreate, FileAccess.Write); 
                System.IO.StreamWriter sw = new StreamWriter(fs); 
                try 
                {
                 string logLine = System.String.Format( 
                 "{0:G}: {1}.", System.DateTime.Now, msg); 
                 sw.WriteLine("\r\nLog Entry : "); 
                 sw.WriteLine(logLine);
                 }
                finally 
                {
                sw.Close();
                 }
