Step 1:
Create a log4net.config file under project root folder .(if desktop app,make it as content and copy always)
Add content like :
(Here the file appender is commented ,and using adonetAppender,you need change to your own username ,password,servername,etc )
<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="false">
<!--
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C://Log4net_LogFile.txt" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<datePattern value=".yyyyMMdd" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="100MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level %logger -%m%n" />
</layout>
</appender>
-->
<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
<param name="BufferSize" value="100" />
<param name="ConnectionType" value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<param name="ConnectionString" value="data source=xxx;initial catalog=xxx;integrated security=false;persist security info=True;User ID=xxx;Password=dxxx" />
<param name="CommandText" value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
<param name="Parameter">
<param name="ParameterName" value="@log_date" />
<param name="DbType" value="DateTime" />
<param name="Layout" type="log4net.Layout.RawTimeStampLayout" />
</param>
<param name="Parameter">
<param name="ParameterName" value="@thread" />
<param name="DbType" value="String" />
<param name="Size" value="255" />
<param name="Layout" type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%t" />
</param>
</param>
<param name="Parameter">
<param name="ParameterName" value="@log_level" />
<param name="DbType" value="String" />
<param name="Size" value="50" />
<param name="Layout" type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%p" />
</param>
</param>
<param name="Parameter">
<param name="ParameterName" value="@logger" />
<param name="DbType" value="String" />
<param name="Size" value="255" />
<param name="Layout" type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%c" />
</param>
</param>
<param name="Parameter">
<param name="ParameterName" value="@message" />
<param name="DbType" value="String" />
<param name="Size" value="4000" />
<param name="Layout" type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%m" />
</param>
</param>
<param name="Parameter">
<param name="ParameterName" value="@exception" />
<param name="DbType" value="String" />
<param name="Size" value="2000" />
<param name="Layout" type="log4net.Layout.ExceptionLayout" />
</param>
</appender>
<root>
<level value="WARN" />
<appender-ref ref="ADONetAppender" />
</root>
</log4net>
Step2
If web app, should add this line in Application_Start method of Global.asax file
log4net.Config.DOMConfigurator.Configure(new System.IO.FileInfo("log4net.config"));
Step3
Add this line in Assembly.cs file
[assembly: log4net.Config.DOMConfigurator(ConfigFile = "log4net.config", Watch = true)]
Now , you can write your code :
this.Logger().Error("My Error");
Here need a ExtensionMethod for easy to use ILog object (Option)
public static class GlobalExtension
{
public static ILog Logger(this object currentView)
{
return LogManager.GetLogger(currentView.GetType());
}
}
