<configSections>

<log4net debug="true">
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\\TestProj\\TestLog.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">

<appSettings>
<add key="log4net.Internal.Debug" value="true" />
</appSettings>Add below lines after system.web section: <system.diagnostics>
<trace autoflush="true">
<listeners>

</listeners>
</trace>
</system.diagnostics>
a. Add namespace
using log4net;
b. Add below declarations within class definition
private static readonly ILog log = LogManager.GetLogger(typeof(TestPage1).Name);OR
private static readonly ILog log = LogManager.GetLogger(
System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
if (log.IsErrorEnabled)
{
log.Error("Page Load failed : " + ex.Message);
}OR if (log.IsDebugEnabled)
{
log.Debug("Application loaded successfully.");
