Hi -
1. I'm using C# and Visual Studio 2008
2. I created a minimal C# that invokes log4net:
using log4net;
using log4net.Config;
...
public class DeleteLogs2 {
private static readonly ILog logger =
LogManager.GetLogger (typeof (DeleteLogs2));
static void Main (string[] args) {
log4net.Util.LogLog.InternalDebugging = true;
logger.Info ("Hello world");
...
3. I have a minimal log4net.xml file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="FileAppender" />
<appender-ref ref="ConsoleAppender" />
</root>
<appender name="FileAppender"
type="log4net.Appender.RollingFileAppender" >
<file value="test-out.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value=".yyyyMMdd" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d{MM/dd/yy HH:mm:ss.SSS} [%C.%M] %-5p %m%n" />
</layout>
</appender>
<appender name="ConsoleAppender"
type="log4net.Appender.ConsoleAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="[%C.%M] %-5p %m%n" />
</layout>
</appender>
</log4net>
</configuration>
4. I downloaded and installed Log4net 1.2.10 (log4net.dll, from log4net-1.2.10\bin\net\2.0\release).
I copied log4net.dll and my log4net.xml into my VS2008 project directory
I added a reference to log4net.dll.
It compiled without error.
VS2008 automagically copied my log4net.xml and log4net.dll into the debug directory, along with TestLog.exe
5. I step through under the VS2008 debugger: I don't see anything written to the console, nor do I get a log file.
6. The only internal debugging output occurs *after* the last line (i.e. during program exit):
"log4net: Hierarchy: Shutdown called on Hierarchy [log4net-default-repository]"
Does anybody have any ideas?

Your log4net.xml configuration should just contain just the log4net node: <?xml version="1.0" encoding="utf-8" ?> <log4net> <root> <level value="DEBUG" /> <appender-ref ref="ConsoleAppender" /> </root> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" > <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="[%C.%M] %-5p %m%n" /> </layout> </appender> </log4net> You have to start log4net by calling one of the Configure methods: static void Main (string[] args) { XmlConfigurator.Configure(new FileInfo("log4net.xml")); logger.Info ("Hello world"); } |

Thank you very much - adding the line you suggested fixed the problem:
XmlConfigurator.Configure(new System.IO.FileInfo("log4net.xml"));: | |
