I'd appreciate some help with this code, either what's wrong with it or even a better way to do it. Here's what I have for writing to the event log: private void WriteToEventLog(string to event log message) { string cs = "QualityDocHandler"; EventLog elog = new EventLog(); if (!EventLog.SourceExists(cs)) { EventLog.CreateEventSource(cs, cs); } elog.Source = cs; elog.EnableRaisingEvents = true; elog.WriteEntry(message); } And here's where I'm trying to call it: private readonly Random _rng = new Random(); private const string _chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; private string RandomString(int size) { try { char[] buffer = new char[size]; for (int i = 0; i < size; i++) { buffer[i] = _chars[_rng.Next(_chars.Length)]; } return new string(buffer); } catch (Exception e) { WriteToEventLog(e.ToString()); return null; } } c# event-log share|improve this question asked Jul 15 '09 at 19:12 PushCode 1,42941726 what line is the error on? –NikolaiDante Jul 15 '09 at 19:13 please provide a stack trace –Brad Barker Jul 15 '09 at 19:16 "Object reference not set to an instance of an object" - means that you are referencing a NULL, it is much more helpful to know the line of code where this happens, because then you can see what it is that is NULL that you're referencing. –Stan R.
