SimpleLog4.NET - Log All The Things

Fast Non-Blocking Zero Allocation Thread Safe Logger for .NET Standard and Greater

All formatting and logging is done in a different thread.


Creating a Simple Log

using SimpleLog4.NET;

Create a new SimpleLog with SimpleLogLevel.Information

SimpleLog Log = new SimpleLog(@"C:\test.txt", logLevel: SimpleLogLevel.Information);

Create a new SimpleLog with SimpleLogLevel.Error that also logs to Console

SimpleLog Log = new SimpleLog(@"C:\loglevelError.txt", true);

Create a new SimpleLog and change the DateFormat

SimpleLog Log = new SimpleLog(@"C:\test.txt", dateFormat: "MM/dd/yyyy HH:mm:ss:fff");

Create a new SimpleLog and change the IFormatProvider

SimpleLog Log = new SimpleLog(@"C:\test.txt", formatProvider: CultureInfo.InvariantCulture);

Write to the Log

Messages

You should always provide the unformatted message to the logging methods

Log.Information("Some Information"); 
// [05/06/24 18:19:19:170][Info] Some Information

Log.Trace();
Log.Debug();
Log.Warning();
Log.Error();
Log.Critical();
Log.Fatal();

Exceptions

Exceptions are specially formatted automatically

Log.Exception(exception); // Exception
// [05/06/24 17:00:27:383][Exception]
// System.ArgumentException | HRESULT: -2147024809
// Message: Invalid Argument
// Stack Trace: 
//    at TestApp.MainContext.TestAll() in C:\Project\Base\MainContext.cs:line 72

WriteExceptionDirect can be used to log Exceptions inside Unhandled Exception Handlers

Log.WriteExceptionDirect(exception); // Skips Queue
