Newbie help for programatically creating log without a config file

[mhgms2]

Hi:

I am trying to create a test program that configures a logger completely 
from code (I want to avoid a config/xml file for this exercise), but 
although I'm not getting any errors, no log file is created.

Can anyone help?

Regards,
Martin.

Here is my code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace log4net
{
 public partial class FrmMainFormLog4Net : Form
 {
   private enum LogDestination { None, File, Access, MsSql }

   private static LogDestination logDestinationType = LogDestination.None;
   private static readonly log4net.ILog log = log4net.LogManager.GetLogger(
     System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

   public FrmMainFormLog4Net()
   {
     InitializeComponent();
     //log4net.Config.XmlConfigurator.Configure();  //--- Load from 
App.Config file
     //log4net.Config.BasicConfigurator.Configure(); //--- Use Console 
output
     setupLogDestino(LogDestination.File);
   }

   private void button_Click(object sender, EventArgs e)
   {
     if(sender == btnDebug)
       log.Debug("*Debug message");
     else if(sender == btnInfo)
       log.Info("**Information message");
     else if(sender == btnWarn)
       log.Warn("***Warning message");
     else if(sender == btnError)
       log.Error("****Error message");
     else if(sender == btnFatal)
       log.Fatal("*****Fatal message", new Exception("My exception 
message"));
   }

   private void destino_CheckedChanged(object sender, EventArgs e)
   {
     RadioButton rb = sender as RadioButton;
     if(rb != null)
     {
       if(rb == rbFile && rb.Checked)
         setupLogDestino(LogDestination.File);
       else if(rb == rbAccess && rb.Checked)
         setupLogDestino(LogDestination.Access);
       else if(rb == rbMsSql && rb.Checked)
         setupLogDestino(LogDestination.MsSql);
     }
   }

   private static void setupLogDestino(LogDestination destination)
   {
     if(destination != logDestinationType)
     {
       log4net.Layout.PatternLayout layout = new 
log4net.Layout.PatternLayout("%d [%t] %-5p %c [%x] <%X{auth}> - 
%m%n");
       switch(destination)
       {
         case LogDestination.File:
           {
             string logFileName = System.IO.Path.Combine(
               AppDomain.CurrentDomain.BaseDirectory,
               System.IO.Path.ChangeExtension(AppDomain.CurrentDomain.FriendlyName, 
".log"));
             log4net.Appender.FileAppender appender = new 
log4net.Appender.FileAppender
               {
                 AppendToFile = true,
                 File = logFileName,
                 Layout = layout,
                 Threshold = log4net.Core.Level.All
               };
             log4net.Config.BasicConfigurator.Configure(appender);
           }
           break;
         case LogDestination.Access:
           //--To do
           break;
         case LogDestination.MsSql:
           //--To do
           break;
       }
     }
   }
 }
