how do I define log file at run time?
I have just started using log4net and I can write to my c# application.
I'm currently writing to the log file "c:\DeIdentifyDicom.log"
Defined in my .config file, but I would like to set the log file name at
runtime. Can anyone help me with this?
Here would be an example and the name of the log I would need to create
at runtime.
Void SomeMethod()
{
String scanCode = ReadScanCode();
//create log called scancode.log
//Log to scancode.log
}
Here is the .config file info I have so far, but this only creates a
staticly named log file
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net"/>
</configSections>
<log4net>
<appender name="ConsoleAppender"
type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger
[%property{NDC}] - %message%newline" />

RE: how do I define log file at run time?
Posted by "Pareto, Charles" <Ch...@va.gov>.
Hi,
I’m having trouble with your code.
Do you think you could send me a more complete example?
Where do I place
var appender = new log4net.Appender.FileAppender(log4net.Layout.PatternLayout.DetailConversionPattern, scanCode+".log");
log4net.Config.BasicConfigurator.Configure(appender);
What do I do with my old code
private readonly ILog logger = LogManager.GetLogger("DeIdentifyDicom"); //defined at top of class
log4net.Config.XmlConfigurator.Configure(); // defined in constructor
and do I need to change my .config file?
Thanks for any help!

RE: how do I define log file at run time?
Posted by "Pareto, Charles" <Ch...@va.gov>.
Isn’t that what I want.
I was able to figure it out. I had to make a call to both
ILog logger = LogManager.GetLogger("DeIdentifyDicom");
log4net.Config.XmlConfigurator.Configure();
each and every time I wanted to log. So I placed everything into a method like so and it seems to work fine:
private void LogFile(string logFileName, string message, Exception ex)
{
log4net.ThreadContext.Properties["Version"] = "1";
log4net.GlobalContext.Properties["LogName"] = logFileName;
ILog logger = LogManager.GetLogger("DeIdentifyDicom");
log4net.Config.XmlConfigurator.Configure();
if (ex != null)
{
logger.Fatal(message, ex);
}
else
{
logger.Fatal(message);
}
}
Is this the best way to do it?
Now every time I want to create a log file in my application at runtime with a new name I just call this and pass in the new ‘logFileName’

But pattern is what I want. Here is a link I followed for creating a dynamic log file name at runtime.

Subject: how do I define log file at run time?
I have just started using log4net and I can write to my c# application. I’m currently writing to the log file “c:\DeIdentifyDicom.log”
Defined in my .config file, but I would like to set the log file name at runtime. Can anyone help me with this?
Here would be an example and the name of the log I would need to create at runtime.
Void SomeMethod()
{
String scanCode = ReadScanCode();
//create log called scancode.log
//Log to scancode.log
}
Here is the .config file info I have so far, but this only creates a staticly named log file

All this %-stuff works only in pattern. Use my code, Luke.

RE: how do I define log file at run time?
Posted by "Pareto, Charles" <Ch...@va.gov>.
I think I’m close but when I try the code below it writes a log file named ‘(null)’ with a size of 0
Any thoughts?
Here is my code:
private readonly ILog logger = LogManager.GetLogger("DeIdentifyDicom");
log4net.Config.XmlConfigurator.Configure();
log4net.GlobalContext.Properties["LogName"] = "scancode.log";
logger.Fatal("Failed to Open File in Time Limit. Filename - " + filePath);

RE: how do I define log file at run time?

I figured out how to change the name of the log file using a pattern to
set the value of the string property, but how do I change the filename
in my source code.
Here is all my code:

//defined at top of class
log4net.Config.XmlConfigurator.Configure(); // defined in constructor
logger.Fatal("Failed to Open File in Time Limit. Filename - " +
