Simplify.Log 2.0.3

Simplify.Log Documentation

Provides ILogger interface and Logger class for file-based log.

With Logger you can write messages to a text log, including just some strings or exception data with full stack trace, line numbers and inner exceptions stack traces.

Available at NuGet as binary package

Simple string log message example:

[01.03.2014 18:24:11:330] Main : Hello world!!!

Exception log message example:

[26.02.2014 13:39:00:023] NHibernate.Exceptions.GenericADOException : could not execute query

General usage

Logger.Default ambient context provides default logger.

• By default, if no Logger configuration exist in config file, data will be written to Logs.log file in current directory (calling assembly location), or web-site root for APS.NET web-sites and WCF services, If a log file size will exceed a limit of 5 mb, then it will be cleaned.

Writing a simple string to a log:

Logger.Default.Write("Hello world!!!");

Writing an exception to a log:

try
{
	...
}
catch (Exception e)
{
	Logger.Default.Write(e);
}

App.config configuration example:

<?xml version="1.0" encoding="UTF-8"?>

<configuration>
	<configSections>
		<section name="Logger" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
	</configSections>
	
	
	<Logger>
		<add key="FileName" value="MyLog.log"/>
	</Logger>
</configuration>

Custom usage

Custom initialization

Logger can be instantiated with specified settings section in config file. Fo example, from MyLoggerSettings section in config file:

var logger = new Logger("MyLoggerSettings");

<?xml version="1.0" encoding="UTF-8"?>

<configuration>
	<configSections>
		<section name="MyLoggerSettings" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0,Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
	</configSections>
	
	
	<MyLoggerSettings>
		<add key="FileName" value="MyLog.log"/>
	</MyLoggerSettings>
</configuration>

Custom configuration

	<Logger>
		
		<add key="FileName" value="C:\Logs\MyApp.log"/>
		<add key="PathType" value="FullPath"/>

		
		<add key="MaxFileSize" value="5000"/>

		
		<add key="ShowTraceOutput" value="true"/>
	</Logger>
