Log4net not inserting data into table - neither shows any error

Question

I tried using log4net for logging info into db and I stuck with it now.Not sure what I am doing wrong.Whatever message i send its not received in the database,neither shows any error

I have a C# basic WINForm application and I am trying to insert log into db.

My log4net.xml below.

<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <root>
    <level value="DEBUG" />
    <appender-ref ref="ADONetAppender" />
  </root>
  <appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
    <bufferSize value="1" />
    <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <connectionString value="Data Source=CTI-OPT780-06\MSSQL2008; Initial Catalog=MYDB; 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>
    <parameter>
      <parameterName value="@context" />
      <dbType value="String" />
      <size value="512" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%x" />
      </layout>
    </parameter>
  </appender>
</log4net>

C# code to access it :

private ILog logger = LogManager.GetLogger(typeof(DBAccess));

public TestDB()
{
    logger.Debug("Here is a debug log.");
    logger.Info("... and an Info log.");
    logger.Warn("... and a warning.");
    logger.Error("... and an error.");
    logger.Fatal("... and a fatal error.");
}

Create table for Log

CREATE TABLE [dbo].[Log]
(
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [Date] [datetime] NOT NULL,
    [Thread] [varchar](32) NOT NULL,
    [Context] [varchar](512) NULL,
    [Level] [varchar](512) NOT NULL,
    [Logger] [varchar](512) NOT NULL,
    [Message] [varchar](4000) NOT NULL,
    [Exception] [varchar](2000) NULL
)

It would really great if someone points me where I m making mistake . Thanks

Answer 1

thanks for your wonderful help .Its so stupid of me I didnt do "configure" .

Added

log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo(sFIleName + "\\log4net.xml")); 

and everything got fixed..

Using the debug trace as told by @sgmoore also helped to fix the db access rights issue.
