Example

Logger log = new Logger("mainlog", new LogCSVFileWriter());
log.Start();
// ...
log.Record("a new log entry");			// To default
log.Record("another log entry");		// To default
log.RecordTo("errorlog", "found an error");	// To errorlog
// ...
log.Stop();

CSV Output:

mainlog-2019-06-28.csv
Jun 28, 19 - 11:14:07:157	a new log entry	13	Main	C:\YourApp\Program.cs
Jun 28, 19 - 11:14:07:158	another log entry	14	Main	C:\YourApp\Program.cs

errorlog-2019-06-28.csv
Jun 28, 19 - 11:14:07:158	found an error	15	Main	C:\YourApp\Program.cs

Customization

By default a log entry contains the following information:

• Timestamp
• Text message
• Source line number
• Calling method
• Source file path

You can add extra information by writing extension structs or classes that inherit from ILogEntryExt.
For example, if you want to include a message type, you can do this:

public enum LogType
{ General, Error, Exception };

public struct LogEntryType : ILogEntryExt
{
	public LogType Type;

	public LogEntryType(LogType type) { Type = type; }
	public string ToCSV() {	return (Type.ToString()); }
}

log.Record("connection established", new LogEntryType(LogType.General));
log.Record("access denied", new LogEntryType(LogType.Error));

CSV Output:

mainlog-2019-06-28.csv
Jun 28, 19 - 11:40:02:530	connection established	General	17	Main	C:\YourApp\Program.cs
Jun 28, 19 - 11:40:02:530	access denied	Error	18	Main	C:\YourApp\Program.cs
