C#

public void WriteLogFile(string fileName, string methodName, string message)
        {
            try
            {
                if (!string.IsNullOrEmpty(message))
                {
                    //using (FileStream file = new FileStream("ErrorLog.txt", FileMode.OpenOrCreate, FileAccess.Write))
                    //{
                        //StreamWriter streamWriter = new StreamWriter(file);
                        StreamWriter streamWriter = File.AppendText("ErrorLog.txt");

                        streamWriter.WriteLine((((System.DateTime.Now + " - ") + fileName + " - ") + methodName + " - ") + message);
                        streamWriter.Close();
                    //}
                }
