Question

I want to make Log4Net to enter logs in MS Sql Server 2005. I am using .NET 2.0.
Here is the code till now I have written:

Web.Config File

<configSections>
  <section  name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<connectionStrings/>
<log4net>
  <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
    <bufferSize value="1" />
    <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <connectionString value="Data Source=XYZ;Initial Catalog=ACC;Integrated Security=True" />
    <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
    <parameter>
      <parameterName value="@log_date" />
      <dbType value="DateTime" />
      <layout type="log4net.Layout.RawTimeStampLayout" />
    </parameter>
    <parameter>
      <parameterName value="@thread" />
      <dbType value="String" />
      <size value="255" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%thread" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@log_level" />
      <dbType value="String" />
      <size value="50" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%level" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@logger" />
      <dbType value="String" />
      <size value="255" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%logger" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@message" />
      <dbType value="String" />
      <size value="4000" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%message" />
      </layout>
    </parameter>
    <parameter>
      <parameterName value="@exception" />
      <dbType value="String" />
      <size value="2000" />
      <layout type="log4net.Layout.ExceptionLayout" />
    </parameter>
  </appender>

</log4net>

Global.asax

<%@ Application Language="C#" %>

<script runat="server">

void Application_Start(object sender, EventArgs e) 
{
    // Code that runs on application startup
    log4net.Config.XmlConfigurator.Configure();

}

Page_load

try
{
    // There is no such Session, this is just to create error
    if (Session["userName"].ToString() == "Admin")
    {

    }
}
catch(Exception ex)
{
    log4net.ILog log =log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); 
    log4net.Config.XmlConfigurator.Configure();  
    log.Debug("log Debug",ex);  
    log.Info("log Info",ex);  
    log.Warn("log Warn",ex);  
    log.Error("log Error",ex);  
    log.Fatal("log Fatal",ex);           
}

Actually I have tried it by storing lod details in Log folder in my directory, which was working fine. But I want to store information in Sql Server 2005.

Am I missing something? or I have to correct some where.

Please help.

Thanks in advance

Answer 1

Unless I made some mistake when I edited your question, then the problem is that you do not reference the appender like this:

<root>
  <level value="ALL" />    
  <appender-ref ref="AdoNetAppender" />
</root>

Some further comments:

• You do not need to call the Configure method twice
• You do not need an exception to test logging
